工业排放烟气中的氮氧化物（NOx）及二噁英( PCDD/Fs)作为重要的大气污染物，对人类生态环境构成严重影响。因此，如何有效控制去除烟气中NOx和PCDD/Fs是当今环境领域的重大课题。本申请项目重点以提高同时脱除PCDD/Fs 和NOx光催化效率为研究目标，通在分子水平上构建(bcc, rh)-In2O3/ZnFe2O4 "多重微结"来实现光生载流子的分离和迁移效率的提高，从而促进光催化NOx和PCDD/Fs效率的进一步提高。在此基础上，将采用同位素标记分子探针技术结合多种原位谱学手段深入研究催化反应机理，这对于在分子水平上深入理解光致电荷分离/迁移/复合过程以及污染物分子在催化剂表面-界面的吸附/分解/脱附微观过程机制具有重要的学术参考价值。本项目的实施将深化人们对复合污染物分子在复杂反应条件下光催化分解特性的进一步认识，对该类化合物的生态风险管理和污染防治具有重要的科学意义。

NOx and PCDD/Fs are typical atmosphere pollutants emitted through indusdrial fume, which do harm to human health and ecological environment seriously.Therefore, nowadays how to control and remove the NOx and PCDD/Fs in indusdrial exhaust gases effectively is a great subject in environmental field. The project in application focuses on the aim of promoting the efficiency of simultaneous removal of NOx and PCDD/Fs through photocatalysis. (bcc, rh)-In2O3/ZnFe2O4 Multi-Junctions will be fabricated on the molecular level to realize the enhancement of photoinduced charge carriers separation and their transfer efficiency, which then leads to the further improvement in the photocatalytic removal efficiency of NOx and PCDD/Fs. Furthermore,combined with various in-situ spectroscopies,the use of isotope labelling molecule-probing techniques, will be employed to reveal the insights of the reaction mechanisms, which will provide in-depth understanding on the processes of photo-induced charges separation/transfer/recombination as well as the important evidences on microscopic mehcanisms about the adsorption /decomposition /desorption processes of pollutant molecues at surface-interface on the molecular level with important academic reference value. The executation of the project will advance the people's knowledge about the photocatalytic decomposition of complex pollutant moleculars under complicated conditions, and thus has important scientifc significance on the ecological risk management and pollution prevention & remedy of such chemicals.
