本发明公开了种复合纳米材料MoS/TiO纳米管阵列的制备方法：将TiO纳米管阵列置于30 mL含KCl、(NH)MoS和NHCl的乙二醇溶液中，采用循环伏安的方法将MoS电沉积于TiO纳米管阵列上，得到复合纳米材料MoS/TiO复合纳米管阵列。MoS/TiO纳米管阵列复合材料，由于MoS是种窄带隙半导体，因此将MoS与宽带隙的TiO复合就可以提高TiO对可见光的吸收以及抑制光生电子和空穴复合的。本发明的催化剂可直接用于有机废水(如4-硝基酚)的光催化处理，修饰了MoS半导体颗粒的TiO光催化剂相比于未修饰的，前者的光催化降解速率是后者1.81倍左右。 The invention discloses a preparation method for a composite nanometer material MoS2/TiO2 nanotube array. A TiO2 nanotube array is arranged in 30 mL of ethylene glycol solution containing KCl, (NH4)2MoS4 and NH4Cl; MoS2 is electrically deposited on the TiO2 nanotube array through a cyclic voltammetry method, and the composite nanometer material MoS2/TiO2 nanotube array is obtained. The MoS2/TiO2 nanotube array is made of composite materials, as the MoS2 is a narrow-band semiconductor, by combining the MoS2 with broad-band TiO2, the absorption of TiO2 to visible light is improved, and photo-induced electrons and electron-hole recombination can be suppressed. Catalysts can be directly used for photocatalysis treatment of organic waste wa
