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.
