Zusammenfassung:Photoelectrocatalytic (PEC) ammonia synthesis from nitrogen and water is a promising approach for energy development and N-neutralization goal under mild conditions. Although significant progress has been made in the past few decades, the mechanisms underlying the synergistic effect between light and electricity are still challenging. One particular line of study is to improve the performances of PEC catalysts, such as selectivity, yield, and stability, etc . Here we review the recent progress in PEC ammonia synthesis. We first provide a systematic description of the driven bias in PEC ammonia processes, involving electrochemical apparatus, photovoltaic voltage, and chemical potential. The various strategies, including vacancy engineering, ion doping, frustrated Lewis pair design, heterojunction construction, cocatalyst loading and single atom synthesis to fabricate new catalysts, are then outlined. The performance and mechanism of PEC N 2 reduction are further summarized, followed by the current challenge and future prospects. This would guide both the productiveness and mechanism of NH 3 synthesis based on advanced PEC systems. Photoelectrocatalytic NH 3 synthesis from N 2 and H 2 O is a promising approach for N-neutralization goal based on catalytic strategies, such as vacancy engineering, ion doping, frustrated Lewis pair design, heterojunction construction, etc .
