ABSTRACT Methanol steam reforming for hydrogen production is a promising hydrogen production technology that can meet the process or operation of hydrogen preparation, storage, transportation, and downstream utilization, contributing to the achievement of carbon neutrality. In this study, copper‐based catalysts Cu x /MCM‐41/HCOOH (x = 0.10, 0.15, 0.25) and Cu 0.15 X 0.01 /MCM‐41/HCOOH (X = Y, Ga, Zr) were prepared by the modified impregnation method using MCM‐41 as the carrier. In addition, the catalysts were comprehensively characterized using a variety of test methods, and the effects of copper content and type of additives on catalyst performance were investigated. Among the six catalysts, the Cu 0.15 Y 0.01 /MCM‐41/HCOOH catalyst exhibited the lowest reduction temperature for CuO, the most effective dispersion of active metal, and the formation of more Cu 0 /Cu + species, demonstrating outstanding catalytic performance. Specifically, the methanol conversion rate achieved 99.85% with a H 2 selectivity of up to 99.91% and CO selectivity and CO 2 selectivity of 1.55% and 98.45%, respectively, at optimal reaction conditions of 250°C, the S/C molar ratio of 3:2, and the weight hourly space velocity (WHSV) of 0.16 h −1 .
