以碳纳米管(CNTs)为载体,分别采用NaBH4、葡萄糖和水合肼3种不同还原剂制备Cu_2O/CNTs复合光催化剂,并表征了不同条件下制备的催化剂,同时考察了其对可溶性染料活性艳红X-3B的光催化活性.结果表明,葡萄糖还原法制备的Cu_2O颗粒均匀,晶型呈完整正八面体型,在可见光、75 min内可使质量浓度为100 mg/L、体积100 mL的X-3B脱色率达到72.4%,COD降解率达到66.7%.

By coating carbon nanotubes surface with Cu_2O three kinds of catalysts are prepared by reduction with hydrazine hydrate,sodium borohydride and glucose,respectively.The morphological structure of the photocatalysts is characterized,and their photocatalytic capabilities are tested by decomposing reactive brilliant red in the aqueous solution.The result shows that the Cu_2O/CNTs which is prepared by glucose has better effect than the other two,and it's a complete octahedral crystal shape with homogeneous granule dispersion and high purity.The photocatalytic degradation rate of reactive brilliant red (100 mg/L in 100 mL) can be 72.4% after 75 minutes,and the COD removal rate can be 66.7%.
