摘　　要：以硝酸锆、PVP和聚乙二醇为原料,通过加入乙二胺及HAc作为表面修饰剂,利用沉淀法合成了纳米二氧化锆催化剂。研究了在不同的煅烧温度、不同光源条件下以及作为载体担载Ag+的纳米二氧化锆催化剂对吸附和光催化降解甲基橙溶液的影响。实验结果表明:制备纳米二氧锆催化剂时,加入不同表面修饰剂制备的催化剂,对甲基橙的吸附和光催化降解效果影响很大。加入乙二胺作为表面修饰剂,能明显提高催化剂对甲基橙的吸附和光催化降解效果。Nano - zirconia catalyst was prepared from zirconium nitrate, PVP and polyethylene glycol by adding ethylenediamine and acetic acid as surface modifier. Effects of nano- zirconia catalyst on the adsorption and catalytic degradation of methyl orange solu- tion were studied under different calcining temperatures, different light sources and load of Ag^＋ . The experimental results show flint using nano - zirconia catalyst parepared by adding Ethylenediamine as a surface modifier , effects of the catalyst on adsorption and catalytic degradation of methyl orange solution can be increased obviously.
