选择性催化氧化NO的催化剂研究进展

工业生产过程产生的NO对大气环境造成严重污染。选择性催化氧化吸收法（SCO）脱硝是目前较有价值的脱硝技术。选择性催化氧化的关键在于催化剂的选择。目前，用于NO催化氧化的催化剂主要有活性炭类、分子筛类、贵金属类、过渡金属氧化物类催化剂。其中，过渡金属氧化物类催化剂具有良好的催化活性，价格低廉，制作简单等，是目前较有研究前景的催化剂。目前，关于SCO各类催化剂脱硝机理的研究，常温下经济实用且氧化、稳定、抗毒性能优良的催化剂的制备，以及催化氧化工业废气工艺的探索是脱硝催化剂未来的发展方向。

RESEARCH PROGRESS IN CATALYSTS FOR SELECTIVE CATALYTIC OXIDATION OF NITRIC OXIDE

The NO produced in the industrial production process causes serious pollution to the atmospheric environment. Selective catalytic oxidation absorption is the most valuable technology for denitration. The key to selective catalytic oxidation lies in the choice of catalyst. At present, the catalysts for catalytic oxidation of NO mainly include activated carbon catalysts, molecular sieve catalysts, noble metal catalysts and transition metal oxide catalysts. Among them, transition metal oxide catalysts have good catalytic activity, low price, simple preparation, etc., and are currently more promising catalysts. So for now, about the mechanism of the SCO all kinds of denitration catalyst, economic practical and oxidation at room temperature, good stability and resistance to toxicity to the catalyst preparation and catalytic oxidation of industrial waste gas process is the development direction of denitration catalyst in the future.
