Evidence Details
Firstly, 0.170 g of ZnCl2 (1.25 mmol), 0.733 g InCl3•4 H2O (2.50 mmol) and 0.375 g thioacetamide (TAA, 5.0 mmol) were added into a flask containing 50 mL of deionized water and stirred for 60 min. The mixture was heated in a microwave-hydrothermal reaction system in a 100 mL Teflon-lined autoclave at 90 ℃ for 30 min, and then at 120 ℃ for 45 min.
The best performing sample, TpBD COF@ZIS-10 (with a ZIS:TpBD COF mass ratio of 10:1), in the absence of a co-catalyst, achieves a visible-light-driven H2 production rate of 2304 μmol g−1 h−1 with an AQE of 5.02% at 420 nm, and exhibits excellent stability.
50 mL of deionized water was used to disperse 52.8 mg of the prepared TpBD COF. After sonication for 10 min, 1.25 mmol of ZnCl2, 2.50 mmol of InCl3•4 H2O, and 5.0 mmol of TAA were added under magnetic stirring. The following procedures, including microwave-hydrothermal reaction and washing, were similar to the synthesis of ZIS.
TpBD COF@ZIS-10 is still able to maintain a high H2 production rate of 2202 μmol g−1 h−1, even after 8 reaction cycles (of 3 h per cycle).
