中文摘要： 消除各类化学污染、保护生态环境、提供无污染可再生能源是促使当前国民经济可持续发展创建绿色地球的核心问题。光催化氧化法有效利用紫外、可见光等光源降解有机污染物，消除污染危害，提供清洁能源是近几年来备受关注的污染治理绿色新技术。本项目拟以多酸/聚苯胺/氧化物三元微/纳米复合材料为研究对象，以"制备方法-微观结构-协同作用-光催化活性"之间的联系为研究思路，系统研究多酸、聚苯胺的协同作用及氧化物颗粒在聚苯胺基体上表面分散、负载情况对半导体材料光催化活性的影响。探索其内在联系，建立一种多酸/聚苯胺/氧化物三元微/纳米复合材料的制备方法。同时降低产品成本，消除粉体团聚影响，提高氧化物光催化活性，为制备具有自主知识产权、性价比高、催化活性高的聚苯胺/氧化物光催化功能材料提供理论支持。

英文摘要： For the sustainable development of national economy and creat green-earth, the removement of chemical pollution for environment protection and clean energy supplies is a hard poject currently. photocatalysis has emerged as one of the most promising pollution-free technologies because it represents an easy way to utilize the energy of either natural sunlight or UV-light illumination to degrade organic pollutant and offer green energy resources.In this project, polyoxometalates/polyaniline/semiconductor oxide ternary micro/nano-composite as subject and the interrelationship of "approach of synthesis-microstructure-synergetic effect-photocatalytic activity"as train of thought were investigated. The synergetic effects of polyoxometalates (POMs) and polyaniline (PANI) followed with the capacity and dispersion of semiconductor particles on PANI matrix, which has an influence on semiconductor oxide's photocalytic activity will be discussed by the number. In addition, we will grope for the internal logic of structure-property and build an approach for preparation POMs/PANI/oxide ternary composite with micro/nano-structure in low cost, decentralized and high photocatalytic activity. Some valuable theory information of photocatalytic material in high activity and cost performance with self intellectual property right for
