2 Synthesis of Control Samples Synthesis of bulk MoS2 The bulk MoS2 was prepared with a hydrothermal method. Typically, 22.4 mg of (NH4)2MoS4 was added into 10 ml of DMF solution and sonicated for approximately 20 min at room temperature until a homogeneous solution was achieved. After that, 0.1 ml of N2H4 H 2O was added to the above solution and was further sonicated for 10 min before transferred to a 25 ml Teflon lined autoclave. It was heated in an oven at 220 C for 24 h and cooled down to room temperature naturally. Product was collected by centrifugation at 9000 rpm for 15 min, washed with DI water and ethanol at least three times respectively to remove DMF. Finally, product was re dispersed in DI water with a concentration of 1 mg/ml, and dried with freeze drying equipment, which was donated as bulk MoS2. Preparation of UiO 66 In a typical synthesis, ZrCl4 (149 mg, 0.64 mmol) and Terephthalic acid (TA, 106 mg, 0.64 mmol) were thoroughly dissolved in DMF (18 ml), and were further sonicated for 10 min. It was transferred into a 40 ml Teflon lined stainless steel autoclave, which was then sealed and heated at 100 o C for 24 h. After cooling, the resultant precipitate was collected by centrifugation, and washed with absolute ethanol for several times, followed by drying under vacuum at 80 o C for 10 h. Preparation of molybdenum polysulfide anchored UiO 66 The synthetic procedure of molybdenum polysulfide anchored UiO 66 was similar as the original UiO 66, except for the addition of (NH 4) 2MoS 4 before solvothermal treatment. The obtained sample was denoted as UiO 66 Mo 5 with mole ratio of Mo/Zr=0.5. S2
