摘要：

石墨相氮化碳(g-C₃N₄)作为一种新型的非金属有机半导体材料在光催化领域受到了人们的广泛关注。为进一步改善它的光电化学性能,本文利用种子生长法和一锅法相结合制备了Au纳米棒/g-C₃N₄复合材料。结果表明,金纳米棒降低了载流子的复合率,使复合材料表现出了较好的光电化学性能。该材料光电流密度可达到17.18 μA/cm²(相对于可逆氢电极),是纯的石墨相氮化碳材料的2.5倍。

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
