Artificial photosynthesis has attracted increasing attention due to recent environmental and energy concerns. Metal halide perovskites (MHPs) demonstrating excellent optoelectronic properties have currently emerged as novel and efficient photocatalytic materials. Herein, the structural features of MHPs that are responsible for the photoinduced charge separation and charge migration properties are briefly introduced, and then important and necessary photophysical and photochemical aspects of MHPs related to photoredox catalysis are summarized. Subsequently, the applications of MHPs for solar energy harvesting and photocatalytic conversion, including H2 evolution, CO2 reduction, degradation of organic pollutants, and photoredox organic synthesis, are extensively demonstrated, with a focus on strategies for improving the performance (e.g., selectivity, activity, stability, recyclability, and environmental compatibility) of these MHP‐based photocatalytic systems. To conclude, existing challenges and prospects on the future development of MHP‐based materials towards photoredox catalysis applications are detailed.

“…Tang et al used density functional theory calculations to elucidate the mechanisms of the reduction of CO 2 to CH 4 using CsPbBr 3 and doped CsPbBr 3 as catalysts. 80 CO 2 was reduced to many intermediates, such as HCOO*, HCO*OH, CO*, and HCO*, before being converted to CH 4 . It can be observed that in the case of Fe-CsPbBr 3 and Co-CsPbBr 3 catalysts, the free energy of intermediates was much lower than in pristine CsPbBr 3 case, as shown in Fig.…”

Organic–inorganic metal halide perovskites (HPs) have emerged as new frontier materials for optoelectronic and energy applications. In addition to various well‐known applications, such as solar cells, light‐emitting diodes, photodetectors, and resistive switching memories, HPs can be utilized as efficient photocatalysts for numerous electrochemical reactions, including carbon dioxide (CO2) reduction reactions, hydrogen evolution reaction, photosynthesis, and wastewater treatment. However, the use of HPs toward photo‐driven catalysis remains a tremendous challenge owing to their poor stability in polar solvents. Nevertheless, huge progress has been made to counter this critical issue for improving the performance of HPs as efficient photocatalysts in a wide range of applications. In this review, we first introduce the structures and properties of HPs. Next, we highlight the recent approaches on the fabrication of HPs, including thin films and nanostructures. Strategies for implementing HPs in catalysis systems and their working mechanisms are thoroughly summarized and discussed. Lastly, the current challenges and prospects of the application of HPs toward photocatalytic reactions are fully addressed. © 2020 Society of Chemical Industry

Doping, introducing impurities in the materials, plays a critical role for junction formation in semiconductor. It directs the flow of charge carriers and improves their transport properties in the thin-film electronic devices including halide perovskite materials based optical-electric devices. Dopants can strongly modify electronic, optical and other properties of materials. Due to the relative smaller size,alkali metals play an important role for halide perovskite materials. In this review, recent research work on the doping of halide perovskite materials byalkali metals, especially the electrochemical doping, have been studied from the view of chemistry and physics.

Design of doped cesium lead halide perovskite as a photo-catalytic CO₂ reduction catalyst

Abstract: The stronger absorption of intermediate molecules, the lower free energy barrier, and the smaller band gap as well as the charge accommodation mechanism compared with the intrinsic case reveal that Co-doped CsPbBr3 could be a promising candidate for CO2 reduction.
