Abstract

Here, we report the encapsulation of Au₂₅ nanoclusters in a Cu₃(BTC)₂ metal–organic framework (Au₂₅@Cu-BTC), which can achieve CO₂ photoreduction for selective CO production in a gas–solid reaction system at low-concentration CO₂ atmospheres (even to 0.1%), with remarkably enhanced durability up to at least 48 h.
