The photothermal effect is applied in CO 2 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.
