摘　　要：采用一步热聚合法制备了g-C_(3)N_(4)/CuO复合材料。通过XRD、SEM、FT-IR和UV-Vis DRS等手段,对材料的物相组成、微观形貌和光吸收性能进行了表征,并测试了材料对甲基橙溶液的光催化降解能力。结果表明,相比纯相的g-C_(3)N_(4),g-C_(3)N_(4)/CuO复合材料具有更好的可见光吸收性,其吸收边界有明显红移,复合材料表现出更为优异的光催化降解甲基橙的能力。当复合材料中CuO的含量为4%时,复合材料表现出最佳的可见光吸收效果及光催化降解效果。经过3h的紫外-可见光照射,复合材料对甲基橙溶液的降解率达到60.82%。The g-C_(3)N_(4)/CuO composite materials were prepared by one-step thermal polymerization.The phase composition,morphology and optical absorption properties of the materials were characterized by XRD,SEM,FT-IR and UV-Vis DRS,and the photocatalytic degradation ability of the materials on methyl orange solution was tested.The results showed that the g-C_(3)N_(4)/CuO composite materials had better visible light absorption than pure g-C_(3)N_(4),the absorption boundary of g-C_(3)N_(4)/CuO was obviously redshifted,which led to the composite materials had better photocatalytic degradation ability on methyl orange.When the content of CuO was 4%in the composite materials,the sample showed the best visible light absorption and photocatalytic degradation abilities.When the mixed solution was exposed under the condition of ultraviolet-visible light for 3h,the degradation rate of methyl orange solution reached 60.82%.
