摘要

氨选择性催化还原(NH₃-SCR)是最常用的控制氮氧化物排放的有效技术之一,由于水蒸气和二氧化硫的存在,商用脱硝催化剂的活性和使用寿命受到限制。核壳结构脱硝催化剂因具有良好的活性、选择性以及优异的抗水、抗硫性能而受到广泛关注。综述了以锰、铁、铜、铈、钴为核的核壳结构脱硝催化剂的研究进展及抗水、抗硫机理,并对其未来研究方向进行了展望。

Abstract

NH₃ selective catalytic reduction (NH₃-SCR) is one of the most commonly used effective technologies to control NO_x emissions.The activity and service life of commercial denitrification catalysts are limited by the presence of water vapor and sulfur dioxide.Core-shell denitrification catalysts have been widely concerned for their excellent activity and selectivity,water resistance and sulfur resistance.The new progress of core-shell denitrification catalysts with manganese,iron,copper,cerium and cobalt as cores and the mechanism of water resistance and sulfur resistance were reviewed,and also discussed the future research directions.
