In CO₂-to-methanol technology, the synergistic efficiency of mass transfer and reaction in three-phase reactors is a key factor restricting conversion performance. Interface enhancement technology can significantly improve the matching between mass transfer rate and reaction activity by optimizing the gas-liquid-solid three-phase interface structure. It enhances the dissolution and diffusion of CO₂ in the liquid phase by regulating bubble dispersion, liquid film thickness, and catalyst surface wettability, while promoting the adsorption and conversion of reaction intermediates on the catalyst surface. Clarifying the synergistic laws of mass transfer and reaction under interface enhancement can provide a theoretical basis for reactor structure design and operating parameter optimization, and is of great significance for improving the conversion rate and selectivity of CO₂ hydrogenation to methanol.
