摘　　要：在“碳中和”和“碳达峰”背景下,甲烷无约束排放问题受到世界各国的极大关注。甲烷催化燃烧可在较低温度下将甲烷完全转化为二氧化碳,是一种高效、环保的净化技术。Pd基催化剂因具有良好的催化性能而应用于甲烷催化燃烧反应,但其催化寿命仍不能满足工业化应用要求。基于目前对甲烷催化燃烧反应的研究,结合2019—2023年发表的以“methanecombustion”为关键词的论文,对目前活性Pd物种(Pd、Pd^(δ+)、PdO和PdO-Pd)、载体种类(Al_(2)O_(3)、CeO_(2)和分子筛)以及催化剂稳定性(抗烧结、抗水蒸气和抗SOx与H_(2)S性能)的研究现状进行了总结,对甲烷催化燃烧的研究前景进行了展望,有助于推进环境的可持续发展和节能减排的目标。In the context of“carbon peak”and“carbon neutral”,methane emission without restriction has received significant attention from countries around the world.Methane catalytic combustion can completely convert methane to carbon dioxide at a low temperature,which is an efficient and environmentally friendly purification technology.Pd-based catalysts are used in methane catalytic combustion due to the excellent catalytic performances,but their catalytic lifetime is still not satisfied with the requirement of industrial implication.Based on current research on methane catalytic combustion reactions,combined with papers published from 2019 to 2023 with the keyword“methane-combustion”,the active Pd species(Pd,Pd^(δ+),PdO and PdO-Pd),support types(Al_(2)O_(3),CeO_(2) and molecular sieves)and catalytic stability(sintering resistance,water vapor resistance and SOx and H_(2)S resistance)were reviewed,and the research prospects of methane catalytic combustion were prospected,which helps to promote sustainable environmental development of environment and the goal of energy conservation and emission reduction.
