- Selective catalytic reduction (SCR) catalysts are a new class of catalysts for NOx removal from vehicle exhaust in the presence of O2. The Ag/Al2O3 monolith catalyst was prepared and studied with various reductants (ethanol and normal octane). 富氧条件下氮氧化物(NOx)去除是目前机动车尾气净化的研究难点之一。 制备了Ag/Al2O3催化剂,在试验室活性评价的基础上,进行了稀燃汽油机台架上NOx选择性催化还原(selective catalytic reduction,SCR)试验,评价了不同还原剂(乙醇和正辛烷)对NOx去除效率的影响。
