Abstract

The photothermal effect is applied in CO₂ hydrogenation to reduce the reaction temperature under illumination by encapsulating Pt nanocubes and Au nanocages into a zeolitic imidazolate framework (ZIF-8). Under illumination, the heat generated by the photothermal effect of Au nanocages is mainly insulated in the ZIF-8 to form a localized high-temperature region, thereby improving the catalytic activity of Pt nanocubes.

Keywords: Au nanocages; CO2 hydrogenation; Pt nanocubes; heat insulation; photothermal effect.
