Accelerating photocatalytic hydrogen production by anchoring Pt single atoms on few-layer g-C3N4 nanosheets with Pt–N coordination

Abstract

g-C3N4 nanosheets are modified with Pt single atoms at 1.5 at% through a low-temperature incipient wetness impregnation method followed by high-temperature pyrolysis, increasing the photocatalytic H2 production rate by two orders of magnitude.
