Metal halide perovskites for CO2 photoreduction: recent advances and future perspectives

“…, SiO 2 , TiO 2 , C 60 , r-GO and g-C 3 N 4 ) can be utilized to shield MHPs from the external environment and enhance their stability. 144,145 Specifically, the surface encapsulation prevents MHPs from coming into direct contact with the external environment and acts as a solid barrier to water and other polar solvents. Physical confinement also inhibits anion exchange and ion migration at the MHP surface.…”

Recent advances in organolead halide crystalline materials for photocatalytic H2 evolution and CO2 reduction applications

“…of metal halide perovskites (including all-inorganic and organic-inorganic hybrid materials). [23][24][25][26] A comprehensive, systematic review about the developed approaches to maintain the structural stability while enhancing the photocatalytic efficiency of the most concerned organolead halide perovskites is scarce. In this Frontier, we briefly summarize the structural diversity and excellent optoelectronic properties of organolead halide perovskites in the first section.…”

Understanding the Effect of the Synthetic Method and Surface Chemistry on the Properties of CsPbBr3 Nanoparticles

“…Lead halide perovskites as thin films or nanoparticles (NPs), either organic-inorganic or all-inorganic, are promising materials [ 1 , 2 ] for many applications, as they exhibit outstanding optical properties, including a high extinction coefficient in the visible range, efficient photoluminescence, and narrow emission line widths [ 2 ], which makes them appealing as active components in solar cells [ 3 , 4 , 5 ] in photodetectors [ 6 ] and as photocatalysts [ 7 , 8 , 9 ]. However, the main limitations towards their large-scale production and commercialization have been mainly ascribed to their poor structural and thermal properties as well as poor photo-stability, all of which cause serious issues in material preparation, storage, application, and device fabrication [ 10 , 11 ].…”
