摘要/Abstract

摘要： 分别采用溶剂热还原和光还原沉积法制备了石墨烯-TiO₂ 和 Ag(Au)/石墨烯-TiO₂ 复合光催化剂, 并表征了其相结构、形貌、孔隙率、光谱吸收性质以及组成结构. 结果表明, 石墨烯与 TiO₂ 通过 C–O–Ti 共价键相互作用, Ag 或 Au 纳米粒子均匀沉积在石墨烯和 TiO₂ 表面. 在模拟太阳光照射下, 通过对水相中罗丹明 B 和甲基橙的降解, 考察了光催化剂活性的差异, 并研究了其降解动力学. 结果表明, 由于量子效率的提高、带隙能的降低以及织构性质的优化, 复合光催化剂表现出比纯 TiO₂ 更高的光催化活性.

Abstract: To improve the solar utilization efficiency of TiO₂, the graphene-TiO₂ and Ag(Au)/graphene-TiO₂ composite photocatalysts were prepared by solvothermal reduction and photoreduction deposition technique, respectively. The phase structure, morphology, porosity, optical absorption property as well as composition and structure of as-prepared materials were characterized. The results indicated that TiO₂ interacts with graphene via Ti–O–C covalent bonds and Ag or Au nano-particles evenly deposite on the graphene and TiO₂ surface. The photocatalytic activity and degradation kinetics of the as-prepared photocatalysts were studied by the degradation of aqueous rhodamine B and methyl orange under solar simulating Xe lamp irradiation. The results indicated that the composite photocatalysts exhibit higher photocatalytic activity compared with pure TiO₂ due to enhanced quantum efficiency, narrowed band gap, and perfect textural properties.

Key words: graphene, titania, silver, gold, solvothermal reduction, photoreduction, rhodamine B, methyl orange
