“…By stripping off the I − ions to form I vacancy, the Pb II sites are verified as the effective binding site for this reaction, Therefore, the MAI-terminated surface with I − vacancy shows better activity (Figure 20B). The MA + cations and I − in (PbI 6) octahedron are both proven to be catalytically inert (Dong et al, 2020b).…”

The halide perovskite material has attracted vast attention as a versatile semiconductor in the past decade. With the unique advantages in physical and chemical properties, they have also shown great potential in photocatalytic applications. This review aims at the specific design principles triggered by the unique properties when employing halide-perovskite-based photocatalytic systems from the following perspectives: (I) Design of photoelectrocatalytic device structures including the n-i-p/p-i-n structure, photoelectrode device encapsulation, and electrolyte engineering. (II) The design of heterogeneous photocatalytic systems toward the hydrogen evolution reaction (HER) and CO2 reduction reaction, including the light management, surface/interface engineering, stability improvement, product selectivity engineering, and reaction system engineering. (III) The photocatalysts for the environmental application and organic synthesis. Based on the analyses, the review also suggests the prospective research for the future development of halide-perovskite-based photocatalytic systems.

“…Such types of hybride perovskites show much affectivity in photocatalytic application due to fast electron and hole mobility, high absorption coefficient, suitable bandgap, reduced rate of electron-hole recombination [33,34]. This type of perovskite is also termed as revolutionized photovoltaics due to their 25.2% power conversion efficiency [35]. The perovskite show excellent properties for dye degradation, hydrogen evolution, CO 2 to CO, photo-polymerization reduction through photocatalytic pathway [35,36].…”

Persistent organic substances in wastewater are creating serious problems to the living world as well as to the environment, thereby creating huge detrimental impact on the ecosystem. In view of the grave situation, removal of the persistent organic substances from wastewater effluent holds a great promise to balance the ecosystem and to sustain societal impact value. In this respect, perovskite based photocatalysts have achieved remarkable attention to the scientific community due to their unique structural features and flexibility of composition. Again, surface polarization and electric dipole-dipole interaction in the perovskite material make them attractive for photocatalytic application. This review paper summarized the photocatalytic activity of perovskite materials and their modification to enhance catalytic activity for wastewater treatment. The modification in perovskite has been done to reduce bandgap energy for enhanced visible light activity, separation of charge carriers for their long lifetime, and fast photocatalytic reaction. The recent investigation of ABO 3 type perovskite, layered perovskite, and halide type of perovskite photocatalysts have been discussed detailly. The modification of corresponding perovskites by doped and formation of heterojunction is investigated carefully. The formation and identification of reactive oxygen species (ROS) and their degradation mechanism by trapping experiment and ESR technique has been summarized here. Finally, large scale with energy and environmental related research should be processed for a permanent solution of wastewater problem.

In the past decade, hybrid organic‐inorganic perovskite solar cells (PSCs) have attracted significant attention. Since then, the power conversion efficiency has astonishingly reached to 25.5%, situating perovskites at the forefront of all reported solution‐processed photovoltaic materials. The research of PSCs has reached a stage where efficiency, stability, and cost need to be simultaneously considered before reaching the threshold for large‐scale commercialization. In this article, the recent progress in fabricating high‐quality perovskite thin‐films adopting “anti‐solvent” strategy is reviewed and the established nucleation and crystal growth mechanisms during the treatment process is discussed. In addition, present challenges and further opportunities of the anti‐solvent methodology toward efficient and large‐scale PSCs are highlighted. The continuous efforts dedicated to the development of anti‐solvent treatment for fabricating high‐performance large‐area devices may pave the way toward commercial applications of PSCs in the near future.
