摘要: 我们报道了一种Pd/Co₃O₄纳米颗粒负载于Al₂O₃纳米片的三元催化剂催化甲烷的高效燃烧。其中，Pd/Co₃O₄负载于碱性氧化铝的复合材料活化甲烷C-H键的能力比SiO₂、ZrO₂和CeO₂以及酸性和中性Al₂O₃为载体时更强，这是因为Pd/Co₃O₄/碱性Al₂O₃拥有更多的氧空穴和吸附氧，对催化剂催化甲烷燃烧有较好的影响。尽管在5%（体积分数）的水蒸气存在下，其催化性能有一定的失活，但在移除水蒸气时，其催化性能可以快速恢复至最佳状态。在模拟真实汽车尾气的氛围下，Pd/Co₃O₄/碱性Al₂O₃依然具有较好的催化甲烷燃烧性能，在400℃时可以催化甲烷完全转化。

Abstract: We report an efficient catalyst composed of ternary components prepared by inlaying Pd/Co₃O₄ nanoparticles in alkaline Al₂O₃ nanosheets for catalytic oxidation of methane. Pd/Co₃O₄ inlaid in alkaline Al₂O₃ exhibited a higher ability to break the C-H bond of methane than Pd/Co₃O₄ supported on SiO₂, ZrO₂, CeO₂, and acidic or neutral Al₂O₃. Our results show more oxygen vacancies and higher amounts of surface adsorbed oxygen on the surface of Pd/Co₃O₄/alkaline Al₂O₃ than on other catalysts, which is responsible for methane activation and conversion. Further, the Pd/Co₃O₄/alkaline Al₂O₃ catalyst can almost restore to its initial value in the absence of water when 5% (volume fraction) vapor water was cut off, although a decrease in activity occurred when water vapor was introduced to the reaction system. Even under a condition similar to the exhaust of a lean-burn natural gas engine, the catalytic performance of the Pd/Co₃O₄/alkaline Al₂O₃ catalyst is excellent, that is, methane could be completely converted when the sample temperature in the reaction atmosphere was ramped to 400℃.
