1 Synergetic Effect of MoS 2 and Graphene as Co-catalysts for Enhanced Photocatalytic H 2 -production Activity of TiO 2 Nanoparticles Quanjun Xiang, a Jiaguo Yu, a,* and Mietek Jaroniec b,* a State Key Laboratory of Advanced Technology for Material Synthesis and Processing, Wuhan University of Technology, Luoshi Road 122#, Wuhan , P. R. China b Department of Chemistry, Kent State University, Kent, Ohio, 44242, USA. *Correspondence authors s: jiaguoyu@yahoo.com, jaroniec@kent.edu Experimental Synthesis of layered MoS 2 /graphene hybrids. Layered MoS 2 /graphene hybrids were prepared by a routine hydrothermal method. All of the reagents were of analytical grade and were used without further purification. Distilled water was used in all experiments. Graphene oxide (GO) was synthesized from natural graphite powder (>99.8%, Alfa Aesar) by a modified Hummers method. In a typical synthesis of MoS 2 /graphene (MG) hybrid, 1 mmol of Na 2 MoO 4 2H 2 O and 5 mmol of thiourea were dissolved in 60 ml of distilled water, and then g of the prepared GO were added into the solution. Next, the homogeneous solution was transferred into a 100 ml Teflon-lined autoclave and held at 210 o C for 24 h. After that, the black precipitate was collected by centrifugation, washed three times with distilled water and ethanol, and then dried in an oven at 80 o C for 12 h. In order to investigate the effect of graphene content in the MoS 2 /graphene hybrid co-catalyst on the photocatalytic hydrogen activity of TiO 2, the weight percentages of GO to Na 2 MoO 4 2H 2 O were varied from 0 to 10 (0, 1.0, 5.0, and 10.0 wt %) by varying the weight of GO; the resulting samples were labeled as (100-x)MxG, where M and G refer to MoS 2 and graphene, respectively, and x = 0, 1.0, 5.0, and 10.0, respectively. Synthesis of TiO 2 /MoS 2 /graphene composite photocatalyst. The composite samples were synthesized by a hydrothermal method. TBOT (Ti(OC 4 H 9 ) 4 ) was used as titanium source. Firstly, 8 mg of the prepared MoS 2 /graphene hybrid (95M5.0G) was sonicated thoroughly in a mixed solution containing 35 ml of ethanol and 70 ml of distilled water for 15 min. Then, the titanium source containing 6.8 ml of TBOT and 35 ml of ethanol was added dropwise under magnetic stirring to the mixture containing MoS 2 /graphene hybrid. After stirring for 2 h, the milky mixture was transferred into a 200 ml stainless steel autoclave with a Teflon liner and kept at 180 o C for 10 h. The resulting precipitate was collected, washed thoroughly with distilled water followed by a rinse in ethanol, and then dried in an oven at 80 o C for 12 h. Similarly, a series of the TiO 2 /MoS 2 /graphene composites was prepared by using the S1

2 (100-x)MxG or graphene as co-catalyst under the same conditions but replacing 95M5.0G with (100-x)MxG or GO. Blank TiO 2 was also prepared following the same procedure as above except that the first addition of MoS 2 /graphene hybrid co-catalyst was eliminated. The detailed data are listed in Table S1. Moreover, in order to further investigate the effect of the content of the MoS 2 /graphene (95M5.0G) co-catalyst on the photocatalytic hydrogen activity of TiO 2, the mass ratio of 95M5.0G/TiO 2 was changed from 0.2% to 3.0% (0.2, 0.5, 1.0, and 3.0 wt %) by varying the amount of 95M5.0G (see Table S2). For the purpose of comparison, 0.5%-95M5.0G-TiO 2 mixture was prepared by simple mechanical mixing of the pristine TiO 2 and 0.5 wt % of 95M5.0G without the hydrothermal process. Characterization. Transmission electron microscopy (TEM) analysis was conducted on a JEM-2100F electron microscope (JEOL, Japan), using a 200 kv accelerating voltage. Scanning electron microscopy (SEM) analysis was performed using a S-4800 microscope (Hitachi, Japan). Powder X-ray diffraction (XRD) patterns were obtained on a D/Max-RB X-ray diffractometer (Rigaku, Japan) with Cu K radiation ( = nm) at a scan rate (2 ) of 0.05 o s -1. The accelerating voltage and the applied current were 40 kv and 80 ma, respectively. The Brunauer-Emmett-Teller specific surface areas (S BET ) and porosity of the samples were evaluated on the basis of nitrogen adsorption isotherms measured at -196 o C using a Micromeritics ASAP 2020 gas adsorption apparatus (USA). All the samples were degassed at 180 o C before nitrogen adsorption measurements. The BET surface area was determined using adsorption data in the relative pressure (P/P 0 ) range of The desorption data were used to determine the pore size distribution via the Barret-Joyner-Halender (BJH) method. 1 The nitrogen adsorption volume at the relative pressure (P/P 0 ) of 0.99 was used to determine the single-point pore volume and the average pore size. X-ray photoelectron spectroscopy (XPS) measurements were performed using an ultrahigh vacuum VG ESCALAB 210 electron spectrometer equipped with a multichannel detector. The spectra were excited using Mg K ( ev) radiation (operated at 200 W) of a twin anode in the constant analyzer energy mode with a pass energy of 30 ev. Raman spectra were recorded at room temperature using a micro-raman spectrometer (Renishaw InVia) in the backscattering geometry with a nm Ar + laser as an excitation source. UV-visible absorbance spectra were obtained for the dry-pressed disk samples by a UV-visible spectrophotometer (UV-2550, Shimadzu, Japan). BaSO 4 was used as a reflectance standard in a UV-visible diffuse reflectance experiments. Photocatalytic testing. The photocatalytic H 2 -production experiments were performed in a 100 ml Pyrex flask at ambient temperature and atmospheric pressure, and three openings of the flask were sealed with silicone rubber septum. A 350 W Xe arc lamp was used as light source (20 cm far away from the photocatalytic reactor). The focused intensity on the flask was ca. 20 mw/cm -2. In a typical photocatalytic experiment, 80 mg of TiO 2 /MoS 2 /graphene composite photocatalyst was suspended in 80 ml of aqueous solution containing 25% of ethanol scavenger in volume. Prior to irradiation, the suspension of the catalyst was dispersed in an ultrasonic bath for 10 min, and then bubbled with nitrogen through the reactor for 40 S2

3 min to completely remove the dissolved oxygen and to assure anaerobic conditions. A continuous magnetic stirrer was applied at the bottom of the reactor in order to keep the photocatalyst particles in suspension status during the whole experiment. A 0.4 ml of gas was sampled intermittently through the septum, and hydrogen was analyzed by gas chromatograph (GC-14C, Shimadzu, Japan, TCD, nitrogen as a carrier gas and 5Å molecular sieve column). All glassware was carefully rinsed with deionized water prior to use. The apparent quantum efficiency (QE) was measured under the same photocatalytic reaction conditions. Four low power UV-LEDs (3 W, 365 nm) (Shenzhen LAMPLIC Science Co. Ltd. China), which were positioned 1 cm away from the reactor in four different directions, were used as light sources to trigger the photocatalytic reaction. The focused intensity and areas on the flask for each UV-LED was ca mw/cm 2 and 1 cm 2, respectively. The QE was calculated according to the following equation: number of reacted electrons QE[%] 100 number of incident photons number of evolved H molecules 2 number of incident photons (1) Photoelectrochemical Measurements. Photocurrent was measured on an electrochemical analyzer (CHI660C Instruments) in a standard three-electrode system using the prepared samples as the working electrodes with an active area of ca. 1.0 cm 2, a Pt wire as the counter electrode, and Ag/AgCl (saturated KCl) as a reference electrode. A low power UV-LEDs (3 W, 365 nm) was used as a light source. 0.5 M Na 2 SO 4 aqueous solution was employed as the electrolyte. The working electrodes were prepared as follows: 0.25 g of the sample was grinded with 0.06 g polyethylene glycol (PEG, molecular weight: 20000) and 0.5 ml ethanol to make a slurry. Then, the slurry was coated onto a 2 cm 1.2 cm F-doped SnO 2 -coated glass (FTO glass) electrode by the doctor blade technique. Next, these electrodes were dried in an oven and calcined at 400 o C for 30 min. All investigated electrodes have a similar film thickness (15 m). S3

The TiO 2 /MoS 2 /graphene composite shows the highest photocurrent density, indicating the improved charge transportation from TiO 2 to graphene and/or MoS 2, and then to the working electrode surface. The photocurrent density of TiO 2 /graphene and TiO 2 /MoS 2 is higher than that of pure TiO 2, indicating that CB electrons of TiO 2 can be injected into the graphene sheets of the TiO 2 /graphene system or into the MoS 2 sheet of the TiO 2 /MoS 2 system. Note that MoS 2 /graphene shows a very low photocurrent density, which is possibly caused by the rapid recombination of the photo-generated electrons and holes on MoS 2. S10

Photocatalytic H 2 -production experiments were performed in 25 vol % ethanol aqueous solutions under UV light irradiation using TiO 2 /MoS 2 /graphene composites as photocatalysts with different amount of MoS 2 /graphene hybrid co-catalyst. For the purpose of comparison analogous experiments were performed for pure TiO 2 and a mechanical mixture of 0.5% MoS 2 /graphene hybrid and TiO 2 (denoted 99.5T + 0.5(MG)). The TiO 2 /MoS 2 /graphene composite photocatalyst with 0.5% MoS 2 /graphene hybrid co-catalyst (99.5T/0.5(MG)) showed the highest H 2 -production rate. This fact indicates that the TiO 2 /MoS 2 /graphene composite with an appropriate amount of MoS 2 /graphene hybrid co-catalyst exhibits a significantly enhanced photocatalytic activity. S11

This figure shows that the composite photocatalysts display stronger broad background absorption in the visible-light region with increasing hybrid content, which was in agreement with the color changing from white to grey. The inset shows the colors of the TiO 2 /MoS 2 /graphene composites with different amount of the MoS 2 /graphene hybrid. The color change from white to grey with increasing content of the black hybrid co-catalyst results in the increased opacity of the TiO 2 /MoS 2 /graphene composite. Figure S12.
