Abstract

AbstractIt is exceedingly desired yet challenging to steer the photocatalytic overall CO2reduction reaction (CRR) toward high-value liquid products, especially multicarbon products like ethanol. Numerous attempts have been reported such as developing new materials, cocatalyst engineering, etc. Here, we find that by just curling the superhydrophobic Cu2O to create an enclosed Cu2O hollow structure, the selectivity of ethanol (59.59%) is impressively elevated by ~ 9 times higher than that without the enclosed hollow structure. Further investigations indicate that the superhydrophobic hollow structure can efficiently repel water out and thus create an enclosed gas storage space, enabling the high concentration of CO2molecules. With such a strategy, an impressive ethanol generation rate of 996.18 µmol g− 1h− 1is achieved. The mechanism is also investigated based on theoretical calculations and corresponding characterizations. This strategy provides a geometry-modulated method with high compatibility, which is promising to develop more efficient photocatalysts for multicarbon production combined with other traditional methods.
