摘要
综述了近年来国内外甲烷燃烧催化剂的研究进展,包括Al2O3负载Pd、有序介孔硅负载Pd、铈基固溶体负载Pd、过渡金属氧化物负载Pd和其他载体负载Pd,负载型Pt、Au和多组分贵金属,非贵金属氧化物,钙钛矿型氧化物,类钙钛矿型氧化物,尖晶石型氧化物,烧绿石型氧化物以及六铝酸盐催化剂。讨论了这些催化剂对甲烷燃烧的活性、水热稳定性和抗硫性能,展望了研发新型高性能甲烷燃烧催化剂的未来发展趋势。
Advancements in the catalysts for the catalytic combustion of natural gas at home and abroad are summarized briefly, including Al2O3 supported Pd, ordered mesoporous silica supported Pd, Ce-based solid solution supported Pd, transition metal oxide-supported Pd, supported Pt, supported Au, supported multiple component noble metals, base metal oxides, perovskite-type oxides, perovskite-like oxides, spinel-type oxides, pyrochlore-type oxides and hexaaluminates. The catalytic activity, hydrothermal stability and SO2 tolerance of these catalysts are discussed. The trend of development for high-performance methane combustion catalysts in future is predicted.
