摘要
通过一种简便的方法合成了一系列的g-C3N4/Cu5FeS4/RGO纳米复合光催化剂,并通过XRD、TEM、UV-Vis等方法对其进行了表征.通过在可见光(λ＞420 nm)照射下降解甲基橙溶液,研究了所制备的g-C3N4/Cu5FeS4/RGO纳米复合光催化剂的光催化性能.通过分析对比,发现g-C3N4/0.75％Cu5FeS4/0.50％RGO具有最佳的光催化降解活性,经可见光照射60 min后,降解了 91％的甲基橙溶液.RGO作为助催化剂,能够加速电子的传输和转移,从而有效抑制电子-空穴对的复合,使g-C3N4/0.75％Cu5FeS4/0.50％RGO纳米复合光催化剂具有较高的光催化效率和更稳定的光催化活性.
Abstract
A series of g-C3N4/Cu5FeS4/RGO nanocomposite photocatalysts were synthesized by a simple method.The nanocomposite photocatalyst was characterized by XRD,TEM,UV-Vis and other methods.The photocatalytic performance of the prepared g-C3N4/Cu5FeS4/RGO nanocomposite photo-catalyst was studied by degrading the methyl orange solution under visible light(λ＞420 nm)irradiation.Through rigorous analysis and comparison,it was finally found that g-C3N4/0.75％Cu5FeS4/0.50％RGO had the best photocatalytic degradation activity.After 60 minutes of visible light irradiation,91％of the methyl orange solution was degraded.The results show that RGO as a cocatalyst can accelerate the transport and transfer of electrons,thereby effectively inhibiting the recombination of electron-hole pairs,resulting in g-C3N4/0.75％Cu5FeS4/0.50％RGO nanocomposite photocatalyst with relatively high pho-tocatalytic efficiency and more stable photocatalytic activity.
