摘　　要：助剂的掺杂对甲醇水蒸气重整制氢催化剂的催化性能起到重要的调节作用。对甲醇水蒸气重整制氢技术的机理进行系统总结归纳,并且围绕过渡金属助剂、稀土金属助剂和其他类型助剂3个方面概括总结了近20年来甲醇水蒸气重整制氢催化剂助剂的研究成果。掺杂助剂后催化剂的结构特征发生改变,例如催化剂比表面积、孔容孔径、活性组分分散度等,以掺杂助剂的方式对催化剂结构进行调控,进而提高催化剂的活性和稳定性。最后对未来助剂掺杂研究以及催化剂的制备方法做出展望,希望本文能够为甲醇水蒸气重整制氢催化剂的研发提供可靠的科学依据。The doping of auxiliaries plays an important role in regulating the catalytic performance of methanol steam reforming catalyst for hydrogen production. In this review, the mechanism of methanol steam reforming hydrogen production technology was systematically summarized. And the research achievements of catalyst auxiliaries for hydrogen production by methanol steam reforming in recent 20 years were also summarized form three aspects:transition metal auxiliaries, rare earth metal auxiliaries and other types of auxiliaries. After doping the auxiliaries, the structural characteristics of the catalyst changed, such as catalyst specific surface area, pore volume and pore size,active component dispersion, and so on. The selective doping auxiliaries could regulate the structural characteristics of the catalyst and improve the activity and stability of the catalyst. In the end, the future research on auxiliaries doping and preparation of catalysts were prospected. It was hoped that this paper can provide a reliable scientific basis for the development of catalysts for methanol steam reforming hydrogen production technology.
