Hydrogenation of CO ₂ to Methanol over Amine‐Doped Ordered Mesoporous Polymers Under Dynamic Reaction Conditions

Abstract A one‐step method was developed to synthesize highly ordered, primary amine–functionalized two‐dimensional (2D) hexagonal mesoporous polymers, designed to enhance the density of catalytically active sites for CO 2 capture and subsequent hydrogenation to methanol. Incorporation of Pt nanoparticles generates an ordered bifunctional (base/metal) mesoporous system, enabling efficient CO 2 adsorption and optimal metal utilization for effective methanol synthesis from the captured CO 2 at the amine–metal interface. Compared with silica‐based materials, [1,2] this novel polymer achieves a fourfold increase in methanol yield while maintaining 100% selectivity under mild reaction conditions.
