Graphdiyne (C n H 2 n ‐2 ) as an “electron transfer bridge” boosting photocatalytic hydrogen evolution over Zn 0.5 Co 0.5 S/MoS 2 S‐scheme heterojunction

Abstract In the process of photocatalytic water cracking, the migration rate and utilization rate of photogenerated charges determine the hydrogen evolution performance of the catalyst. In this paper, a carbon isotope superconducting material graphdiyne (GDY) is prepared by mechanical ball milling and introduced into the S‐scheme heterojunction Zn 0.5 Co 0.5 S/MoS 2 inorganic system. In terms of hydrogen evolution kinetics, GDY acts as an electron bridge, not only accelerating the migration of photogenerated carriers but also improving the utilization of photogenerated charges. Morphologically, the large two‐dimensional layer provides more loading and anchoring points for Zn 0.5 Co 0.5 S/MoS 2 , which…
