Technical Field

[0001] This utility model relates to the field of photocatalyst reaction technology, specifically a multifunctional three-phase photocatalyst mounting platform. Background Technology

[0002] The catalyst-carrying platform is an innovative technology platform for the rational control of the photocatalytic reaction interface. By constructing a solid-liquid-gas three-phase reaction system, this platform greatly improves the speed and efficiency of the photocatalytic reaction. Traditional photocatalytic reaction systems often face challenges such as electron-hole recombination and insufficient oxygen supply. However, the three-phase reaction system effectively promotes the separation of electrons and holes and increases the oxygen transport rate by introducing the gas phase, thereby significantly improving the kinetic performance of the catalytic reaction.

[0003] Currently, photocatalytic CO2 reduction devices are mainly used in solid-gas reaction systems and solid-liquid reaction systems. Solid-gas reaction systems improve photocatalytic activity by reducing mass transfer resistance during gas dissolution and increasing the utilization of sunlight. In solid-liquid reaction systems, dissolved gas molecules can more easily reach the catalyst surface and stabilize intermediates in the reaction process. However, in practical applications, both catalytic systems face the problem of large mass transfer resistance, which is reflected in different stages of molecular diffusion, thus affecting the actual reaction.

[0004] Therefore, a multifunctional three-phase photocatalyst mounting platform is proposed. Utility Model Content
