A spinel-alumina inert oxide supported gold catalyst with high Au dispersion and excellent CO oxidation activity was developed by a deposition–precipitation method. The activation atmosphere could tune the reaction pathway by adjusting the amount of surface adsorbed water species, thus transforming the reaction intermediates from HCO₃⁻ or CO₃²⁻ to COOH.

一种用于高效 CO 氧化的新型 Zn-Al 尖晶石-氧化铝复合负载金催化剂

通过沉积-沉淀法开发了具有高Au分散性和优异CO氧化活性的尖晶石-氧化铝惰性氧化物负载金催化剂。活化气氛可以通过调节表面吸附水物质的量来调整反应途径，从而将反应中间体从 HCO ₃^-或 CO ₃^2-转化为 COOH。
