处理亚甲基蓝液相污染物负载型光催化剂及其制备方法和应用方法
摘要：
本发明涉及一种负载型光催化剂及其制备方法和应用方法。技术方案包括处理亚甲基蓝液相污染物的负载型光催化剂以树脂作为粘结剂将纳米二氧化钛粉体固定于活性炭纤维表面，然后于氮气氛下煅烧使残余物作为二者之间的粘结体。二氧化钛的负载量为25－55％，煅烧温度为400－550℃制得的。该催化剂在紫外光照下，可将水溶液中亚甲基蓝等有机污染物消除，降解效率达到99％以上，而且在循环使用的过程中，其效率基本上保持不变。
摘要（英）：

The present invention relates to one kind of supported photocatalyst and its preparation process and application. The technological scheme is that the supported photocatalyst for treating liquid methylene blue pollutant is prepared fixing nanometer TiO2 powder onto the surface of active carbon fiber with resin as adhesive and the subsequent calcining in nitrogen atmosphere to obtain the supported photocatalyst adhered with the residue. The supported photocatalyst has TiO2 supporting amount of 25-55 wt% and calcining temperature of 400-550 deg.c. Under illumination of ultraviolet ray, the supported photocatalyst can eliminate methylene blue and other organic pollutant from water solution in the degradation efficiency up to 99 % and basically unchanged circularly using efficiency.
