Abstract

Abstract:

Graphite phase carbon nitride(g-C₃N₄), a new type and non-metallic organic semiconductor material has attracted widespread attention in the photocatalysis area. In this paper, we combined a seed-mediated growth way with one pot method to synthesize Au nanorods/g-C₃N₄ composites to improve its photoelectrochemical properties. The results demonstrate that Au nanorods can decrease the recombination rate of photogenerated carriers. Therefore, the composites present excellent photoelectrochemical properties, and the photocurrent density can reach 17.18 μA/cm²(vs RHE)which is 2.5 times higher than that of pristine samples.

Key words: graphite phase carbon nitride, Au nanorods, one pot method, photoelectrochemistry
