In this article, a triple-layer photocathode was fabricated by using a layer-by-layer assembly method for photoelectrochemical hydrogen evolution, and the chemically inert g-C3N4 layer was electrodeposited on the FTO as the active layer for light harvesting.Abstract:
A Cu2O/g-C3N4/WS2 triple-layer photocathode was fabricated by using a layer-by-layer assembly method for photoelectrochemical hydrogen evolution. Cu2O was electrodeposited on the FTO as the active layer for light harvesting. The chemically inert g-C3N4 can protect the unstable Cu2O layer and form a p-n junction with Cu2O to increase the light-to-electricity conversion efficiency. Mixed-phase WS2 nanosheets were obtained through a lithium insertion method and used as an effective hydrogen evolution catalyst for photocurrent-to-hydrogen conversion. This photocathode is effective for photoelectrochemical hydrogen evolution, and a photocurrent of −9.5 mA cm−2 at −0.55 V versus RHE (pH 6.0) can be obtained under visible light (λ≥420 nm, 100 mW cm−2).read more
