1 Supporting Information Pt Nanoparticles Anchored Molecular Self-Assemblies of DNA: An Extremely Stable and Efficient HER Electrocatalyst with Ultra-Low Pt Content Sengeni Anantharaj, $ Pitchiah E. Karthik, # Balasubramanian Subramanian $ and Subrata Kundu $ * $ Electrochemical Materials Science (ECMS) Division, CSIR-Central Electrochemical Research Institute (CECRI), Karaikudi , Tamil Nadu, India. # Department of Chemistry, Indian Institute of Science Education and Research (IISER) Mohali, Punjab, India. * To whom correspondence should be addressed, skundu@cecri.res.in; kundu.subrata@gmail.com, Phone: (+ 91) , FAX: Materials. Platinic acid (H 2 PtCl 4 ), sodium borohydride (NaBH 4 ), sodium salt of DNA from salmon testes, 5 wt. % solution of Nafion in propanol and water mixture and the commercial Pt/C 10 wt. % catalyst were obtained from Sigma Aldrich and used without any further purification. Conc. sulphuric acid was obtained from RANKEM, India. Ultra-pure water (18.2 MΩ.cm) was used throughout the synthesis and in electrochemical studies and other places wherever required. A glassy carbon (GC) disc electrode of geometrical surface area cm 2 was used as substrate for working electrode fabrication. Hg/HgSO 4 reference electrode filled with saturated potassium sulphate (K 2 SO 4 ) was used in 0.5 M H 2 SO 4 electrolyte along with a Pt-foil counter electrode were used in a three electrode electrochemical system taken for the HER performance evaluation of our colloidal Pt@DNA molecular self-assemblies. Instruments Used for Materials Characterizations. The synthesized colloidal Pt@DNA molecular self-assemblies were characterized with HR-TEM, (Tecnai TM G 2 TF20) working at an accelerating voltage of 200 kv. TheEnergy Dispersive X-ray Spectroscopy (EDS) analysis was done with the FE-SEM instrument (Oxford)
2 with a separate EDS detector connected to that instrument and the same instrument was used to study the morphology of the synthesized colloidal Pt@DNA molecular self-assemblies. The XRD analysis was carried out with a scan rate of 5 min -1 in the 2θ range using a Bruker X-ray powder diffractometer (XRD) with Cu K α radiation (λ = nm). X-ray photoelectron spectroscopic (XPS) analysis was performed using a Theta Probe AR-XPS system (Thermo Fisher Scientific, UK). Electrochemical analyzer CHI6084c version was used for the entire HER and related studies. Hg/HgSO 4 reference electrode was used along with a Pt counter electrode while colloidal Pt@DNA molecular self-assemblies modified GC electrodes were used as working electrode. Sample Preparation Methods for Various Characterizations. The synthesized colloidal Pt@DNA molecular self-assemblies were characterized using UV-Vis, TEM, EDS, XRD, XPS and FT-IR analysis studies. The colloidal Pt@DNA molecular self-assemblies were directly used for the absorption measurement in UV-Vis spectrophotometer. The same liquid solution was used for the TEM sample preparation and other thin films preparation. The samples for TEM was prepared by placing a drop of the as synthesized colloidal Pt@DNA molecular self-assemblies onto a carbon coated Cu grid followed by slow evaporation of solvent at ambient conditions. For EDS, XRD, XPS and FT-IR analysis, glass slides were used as substrates for the preparation of thin films. The slides were cleaned thoroughly with acetone and sonicated for about 30 min. The cleaned substrates were covered on one side with the colloidal Pt@DNA molecular self-assemblies and then dried in air. After the deposition of first layer, subsequent layers were deposited by repeatedly adding more colloidal Pt@DNA molecular self-assemblies solution. Final samples were obtained after depositions and then analyzed using the above techniques. Determination of Number of Pt Atoms in both Loaded Pt@DNA and the Pt/C Catalysts. The number Pt atoms in the loaded catalysts is calculated based on Avogadro s method with use of density of the crystal system at which it crystallized during the synthesis and the covalent radii of Ptas follows: For Pt@DNA of loading 15 µg:
3 Wt. of Pt taken=1.5*10-5 g ρ = g/cm 3 V = w/ρ = (1.5*10-5 /21.45)*10 21 = 7*10 14 nm 3 R=139 pm = nm V = 1.33*3.14* = nm 3 N = V/V = 7*10 14 / = 6.2*10 17 Wt. of Pt = W/N -= 1.5*10-5 /6.2*10 17 = 2.4*10-23 g 1NA=195.08g 1g = 1/ *10-23 = 2.4*10-23 *6.023*10 23 / = 0.074atoms/NP No of Pt atoms = 0.074*6.2*10 17 = 4.59*10 16 atoms For Pt/C 10 wt. % of loading 20.5 µg: W=2.05*10-5 g ρ=21.45 g/cm 3 V=w/ρ = (2.05*10-5 /21.45)*10 21 = 9.56*10 14 nm 3 R=139 pm = nm V = 1.33*3.14* = nm 3 N = V/V = 9.56*10 14 / = 8.59*10 16 Wt. of Pt = W/N -= 2.05*10-5 /8.59*10 16 = 2.4*10-22 g 1NA=195.08g 1g = 1/ *10-22 = 2.4*10-22 *6.023*10 23 / = 0.74atoms/NP No of Pt atoms = 0.74*8.59*10 16 = 6.36*10 16 atoms Determination TOF at an Overpotential of 0.02 V for both Pt@DNA-GC Interface without Binder and the Pt/C-GC Interface with Binder. Turnover frequency for oxygen evolution reactions is usually done in more than one way. Here we have made a primary assumption of 100% activity and participation of all the Fe atoms in OER and the calculated Fe atoms as shown above is used here as surface concentration. The
4 following equation is used to calculate the TOF value at an overpotential (ŋ) of 359 mv for both Sn-FeHP and FeHP. TOF= i N A / A F n ᴦ Where, i = current N A = Avogadro number A = Geometrical surface area of the electrode F = Faraday constant n = Number of electrons ᴦ = Surface concentration We have taken the HER current density at the overpotential of 20 mv for both Pt@DNA-GC interface without binder and the Pt/C-GC interface with binder. Hence for Pt@DNA-GC interface without binder; TOF ŋ = 26 mv = [( ) ( )] / [(1) (96485) (2) ( )] TOF ŋ = 26 mv =15.810s -1 Similarly for Pt/C-GC interface with binder; )] TOF ŋ = 26 mv = [( ) ( )] / [(1) (96485) (2) (6.36 TOF ŋ = 26 mv = 0.153s -1
