Preparation of Pt/MoO3/ZrO2 Catalyst and its Property of Three-Way Catalysts
Source abstract
Abstract
采用浸渍法制备了MoO3/ZrO2,用低温氮吸附-脱附法和NH3-程序升温脱附法（TPD）分别对其比表面积和酸碱性进行了表征.结果表明,MoO3/ZrO2具有106.8m~2/g的比表面积和超强酸的性能.用等体积浸渍法制备了Pt/MoO3/ZrO2催化剂,在汽车尾气模拟气中考察了其对C3H8、CO和NO的催化活性.与传统三效催化剂Pt/La2O3/Al2O3相比较,Pt/MoO3/ZrO2具有更好的低温起燃性能和更宽的空燃比窗口,并显著地改善了C3H8在富氧状态下的转化效率.通过XRD、H2-TPR对催化剂进行了表征,结果表明,Pt在催化剂载体上具有高度的分散性和优异的氧化还原性能.
