We are pleased to share that our recent study on the Al-PMOF photocatalyst for NRR was just accepted by the prestigious journal of SMALL. In this study, the Zn ions-inserted Al-PMOF photocatalyst is designed for photocatalytic ammonia synthesis from NRR. The enriched Zn-N4 active sites contribute to the superior adsorption and activation of N2, excellent charge separation and transfer, and strong reduction ability, significantly promoting the photocatalytic NRR performance. In particular, an important contribution of this study is investigating the influence of the level of d-orbital occupation on regulating the charge transportation and band structure of the Al-PMOF.
