High alkalinity boosts visible light driven H2 evolution activity of g-C3N4 in aqueous methanol

Author affiliations

Abstract

A high rate of 2.23 mmol h−1 g−1 (quantum efficiency of 6.67% at 400 nm) for visible light driven photocatalytic H2 evolution can be achieved with g-C3N4 by alkalization of the solution to a pH of 13.3, due to accelerated transfer of photoholes to the sacrificial donor.
