This study investigated the hydrogenation of carbon dioxide (CO₂) to methanol (CH₃OH) under low-temperature conditions (around 200 ℃) using Pt/MoO_x/TiO₂ catalysts.The effects of the Mo/Pt molar ratio, reduction temperature, catalyst preparation method (co-impregnation and sequential impregnation), and the crystalline structure of the TiO₂ support on catalytic activity and selectivity were systematically evaluated.In addition, the correlation between the electronic and structural properties of Pt and Mo and the catalytic performance was examined, along with a mechanistic consideration of the possible reaction pathways leading to methanol formation.
