摘　　要：以乙酸锌和尿素作为前驱体,制备不同物质的量比的ZnO/g-C_(3)N_(4)复合材料。对材料进行红外光谱和X射线衍射光谱表征,证明了ZnO/g-C_(3)N_(4)复合材料的成功制备。在500 W Xe灯作为光源的条件下,对亚甲基蓝溶液进行光催化降解研究,根据降解结果发现ZnO/g-C_(3)N_(4)复合物质的量比为1∶1时的降解效果最佳;催化剂用量为5 mg、溶液pH值为7的条件下,展现出最佳的光催化降解性能,在这些最佳条件下,经过120 min的光催化反应,亚甲基蓝的光催化降解率达到了81%。ZnO/g-C_(3)N_(4) composites with different molar ratios were prepared using zinc acetate and urea as precursors.The materials were characterized by infrared spectroscopy and X-ray diffraction,and the preparation of ZnO/g-C_(3)N_(4) composites was proved.Under the condition of 500 W Xe lamp as the light source,the photocatalytic degradation of methylene blue solution was studied.According to the degradation results,it was found that the degradation effect was best when the composite molar ratio of ZnO/g-C_(3)N_(4) was 1∶1.Under the conditions of 5 mg catalyst and pH value of solution 7,the optimal photocatalytic degradation performance was demonstrated.Under these optimal conditions,after 120 minutes of photocatalytic reaction,the photocatalytic degradation rate of methylene blue reached 81%.
