稀土催化材料在工业废气、人居环境净化中的研究与应用综述

阐述了稀土催化材料在工业废气、人居环境净化方面的研究与应用现状,并对稀土催化材料的发展进行了展望,认为将稀土催化材料用于工业有机废气污染治理和人居环境净化,是推动稀土催化应用的动力之一。等离子体辅助的催化技术,可以显著改善低温活性。作为长期去除污染物的有效措施,光催化技术应大力开发。开发联合脱硫脱氮的新方法、新理论、新技术及新设备,将成为烟气净化技术发展的总趋势。作为一种新型催化材料应用,掺杂稀土的ABO3钙钛矿复合氧化物以及TiO2为基础的复合氧化物,在环境净化方面的发展方向是努力降低成本,提高光催化剂活性,尽量多利用太阳光,扩大降解范围。

RESEARCH AND APPLICATION OF THE RARE EARTHS CATALYTIC MATERIALS IN PURIFICATION OF INDUSTRIAL EXHAUST GAS AND LIVING SURROUNDINGS

This paper expatiates on the research and application of the rare earth catalytic materials in purification of industrial exhaust gas and living surroundings and the prospect of the rare earth catalytic material development.The application of the rare earth catalytic materials in these fields pushes progress of the rare earth materials applications.Low temperature activities of catalytic material are observably improved by catalytic technology of plasma assistant.By way of an effective measure to eliminating polluters,photocatalytic technology should be greatly impoldered.A general trend of smog purification technology development is developing new methods,theories and equipments of combined desulfurization and denitrification.The ABO3 perovskite doped by the rare earth and TiO2 based mixed oxides are new catalytic material.The progress direction of environmental purification is reducing cost,increasing activity of photocatalysts,using sunlight to the best of one's abilities and enlarging degradation ranges.
