Photogenerated hole traps in metal-organic-framework photocatalysts for visible-light-driven hydrogen evolution

Abstract

Efficient electron-hole separation and carrier utilization are key factors in photosynthetic systems. Here, the authors achieve efficient charge separation following a photogenerated hole-transfer band-trap pathway in the ternary composite Pt@NH2-UiO-66/CdS, resulting in photocatalytic hydrogen evolution with good stability and a quantum efficiency of 40.3% at 400 nm irradiation.
