Unraveling the role of surface and interfacial defects in hydrogen production to construct an all-in-one broken-gap photocatalyst

Abstract

A rational design of WO3−x/ZnFe2O4−x broken-gap heterojunction achieved higher charge carrier separation, light-harvesting ability, and good surface reaction, as an all-in-one photocatalyst for H2 generation.

A brief review of hydrogen production technologies

“…Li et al [70] conducted a DFT-calculations-supported characterization experiment by locating the broken-gap heterojunction at the interface or surface. The results showed that the broken-gap heterojunction rich in defects had higher carrier separation and light collection ability and good surface reaction.…”
