有 NH ₃ 的没有 _x 的选择催化减小(SCR ) 是一种有效技术不把 _x 从静止来源移开，例如开火煤的发电厂和工业锅炉。一些在苍蝇灰的元素撤销催化剂由于活跃地点上的强壮的化学吸着。毒物可以由简单地堵住活跃地点行动或由一个电子相互作用改变反应物和产品的吸附行为。这评论主要集中于在 V ₂ O ₅-based 催化剂，环境良性的催化剂和低温度催化剂。几普通毒物包括 alkali/alkaline 地球金属， ₂ 和重金属等等因此被提交，他们催化剂上的毒害的机制被讨论。毒害的催化剂的新生方法和毒物抵抗催化剂的发展也被比较并且分析。最后，在发展毒害抵抗催化剂的未来研究方向和为 SCR 催化剂的灵巧的有效新生方法被建议。

英文摘要：

Selective catalytic reduction （SCR） of NOx with NH3 is an effective technique to remove NOx from stationary sources, such as coal-fired power plant and industrial boilers. Some of elements in the fly ash deactivate the catalyst due to strong chemisorptions on the active sites. The poisons may act by simply blocking active sites or alter the adsorption behaviors of reactants and products by an electronic interaction. This review is mainly focused on the chemical poisoning on V2O5-based catalysts, environmental-benign catalysts and low temperature catalysts. Several common poisons including alkali/alkaline earth metals, SO2 and heavy metals etc. are referred and their poisoning mechanisms on catalysts are discussed. The regeneration methods of poisoned catalysts and the development of poison-resistance catalysts are also compared and analyzed. Finally, future research directions in developing poisoning resistance catalysts and facile efficient regeneration methods for SCR catalysts are proposed.
