Congratulations to Hong Wang et al. on their publication in Advanced Science, “Heterostructure Engineering of a Reverse Water Gas Shift Photocatalyst”

The paper describes a heterostructure engineering strategy that enables the gas-phase, photocatalytic, heterogeneous hydrogenation of CO2 to CO with high performance metrics. The catalyst is comprised of indium oxide nanocrystals (In2O3-x(OH)y) nucleated and grown on the surface of niobium pentoxide nanorods. Materials characterization demonstrates that the Nb2O5 support in the In2O3-x(OH)y@Nb2O5 heterostructure increases the number of oxygen vacancies and lengthens the excited state charge carrier lifetimes in the attached In2O3-x(OH)y nanocrystals, which results in a 44-fold higher conversion rate than pristine In2O3-x(OH)y selective conversion of CO2 to CO as well as long-term operational stability. Overall, the results of this study bode well for the general applicability of the heterostructure engineering approach for optimizing the performance of photocatalytic heterogeneous CO2 conversion reactions.
