摘要
催化剂是选择性催化还原脱硝技术的核心,其催化性能直接关系到脱硝效果的好坏。本文介绍了该领域新开发的贵金属、金属氧化物、分子筛、碳基催化剂等低温脱硝体系及其最新研究进展。对碳纳米材料催化剂和新型杂多酸催化剂等新成果作了介绍,并且对今后的研究方向作了展望。
Catalyst is the key to the selective catalytic reduction (SCR) of NOx, and its catalytic performance directly affects the removal effect of NOx. A review of deNOx catalysts in recent years, including noble metals, metal oxides, molecular sieves, carbon-based catalyst was presented. Several new catalyst, which involve carbon nanometer materials (CNTs) catalysts and solid heteropoly acids catalysts were introduced. The catalysts, which use carbon materials as support and solid heteropoly acids catalyst show outstanding low temperature activity, strong thermal stability and high deNOx efficiency, with promising industrial application. At last, some useful comments about the future directions of research were amde.
