Over two-orders of magnitude enhancement of the photocatalytic hydrogen evolution activity of carbon nitride via mediator-free decoration with gold-organic microspheres

Abstract

A mediator and Pt free photocatalytic system is created for H₂ production over AuNPs/g-C₃N₄ hybrids under visible light irradiation. In contrast to pure g-C₃N₄ and state-of-the-art 3 wt% Pt loaded g-C₃N₄, ingeniously decorating minute AuNPs onto g-C₃N₄ can enhance the catalytic activity by about 348 and 25 times, respectively.
