Unveiling the Bifunctional Photo/Electrocatalytic Activity of In Situ Grown CdSe QDs on g-C 3 N 4 Nanosheet Z-Scheme Heterostructures for Efficient Hydrogen Generation

The successive ionic layer adsorption and reaction (SILAR) method was used to deposit several CdSe quantum dots (QDs) on the surface of g-C3N4 nanosheets. In comparison to the single moiety of g-C3N4, as-prepared heterostructures displayed an improved bifunctional photo- and electrocatalytic activity for oxygen (OER) and hydrogen evolution reactions (HER). Significantly, the 30 SILAR cycles optimized CdSe QDs/g-C3N4 heterostructure exhibited high performances and stabilities for the OER and HER reaction in alkaline conditions. The as-prepared heterostructure catalyst also exhibited an efficient photocatalytic activity toward the H2 evolution reaction and produced 4306 μmol of H2 gas with 23.8% of apparent…
