汽车尾气净化问题一直备受实验和理论研究工作者的关注。如果能将有毒性的CO转化为无毒CO2再排放到空气中去,那么尾气对环境的污染将明显降低,达到环境保护的目的。此前研究发现金-氧化物复合材料具有这样独特的催化性能,并且在室温条件下就可以促进这一反应的进行,因此引起了 Automotive exhaust purification has been the subject of experimental and theoretical research workers attention. If toxic CO can be converted into non-toxic CO2 and then discharged into the air, the pollution of the exhaust gas to the environment will be significantly reduced, thus achieving the goal of environmental protection. Previous studies have found that gold-oxide composite has such a unique catalytic properties, and at room temperature can promote the progress of this reaction, thus causing
