Photocatalytic H2 Evolution

Modifying g-C3N4 with covalent organic frameworks (COFs) through imine linkage results in a dramatically enhanced visible-light-driven photocatalytic hydrogen evolution, which reached 10.1 mmol g−1 h−1 when 2 wt% Pt and triethanolamine were used as co-catalyst and sacrificial agent, respectively, corresponding to an apparent quantum efficiency (AQE) of 20.7% at 425 nm.

In this work, a super-paramagnetic nano-architecture, which could be separated and re-dispersed easily for reuse, was designed for effective visible-light-driven H2 evolution. The photo-catalytic performance was remarkably enhanced by the electron-transfer and surface-repair ability of graphene, and the high activity of the exposed Pt(111) facet.
