以石墨化碳氮化物(g-C3N4)为光催化剂，在可见光照射下，超声辅助液体剥离体相g-C3N4对Au(III)进行绿光还原，将Au纳米粒子负载到石墨化碳氮化物(g-C3N4)上。这些纳米杂化材料在可见光照射下对甲基橙的分解表现出了优异的光催化活性，得到了块状g-C3N4、g-C3N4纳米片和AuNP/块状g-C3N4杂化材料。
Au nanoparticles (AuNPs) were loaded on graphitic carbon nitride (g-C3N4) nanosheets prepared by ultrasonication-assisted liquid exfoliation of bulk g-C3N4 via green photoreduction of Au(III) under visible light irradiation using g-C3N4 as an effective photocatalyst. The nanohybrids show superior photocatalytic activities for the decomposition of methyl orange under visible-light irradiation to bulk g-C3N4, g-C3N4 nanosheets, and AuNP/bulk g-C3N4 hybrids.
