摘要
采用浸渍法制备的以稀散元素Re ,In ,Ge为基的汽车尾气净化催化剂STR/r -Al2 O3 ,对尾气中CH4 的氧化率近 10 0 %,起效温度约 4 0 0℃ .
The purifing automobile exhaust catalysts (STR/r-Al 2O 3), based on scattered elements such as Re, In and Ge, have been prepared by the dipping process. The oxidation rate for CH 4 in exhaust is nearly 100%, and the actuating temperature is about 400℃.
