Halide perovskites (HPs), renowned for their intriguing optoelectronic properties, such as robust light absorption coefficient, long charge transfer distance, and tunable band structure, have emerged a focal point in the field of photocatalysis. However, photocatalytic performance HPs is still inhibited by rapid recombination, insufficient potential energy, limited number surface active sites. To overcome these limitations, integration two-dimensional (2D) materials, characterized shortened pathways expansive areas, into HP/2D heterostructures presents promising avenue to achieve exceptional interfacial including extensive absorption, efficient separation transfer, energetic redox capacity, adjustable characteristics. Herein, comprehensive review delving fundamentals, engineering, carrier dynamics material presented. Numerous photocatalysts fabricated through diverse strategies architectures are systematically described categorized. More importantly, enhanced properties thoroughly investigated discussed. Finally, an analysis challenges faced development photocatalysts, alongside insightful recommendations barriers, provided.

Abstract Perovskite quantum dots exhibit a high carrier photogeneration rate upon light absorption but are hindered by rapid recombination and low stability in polar environments. These critical issues limit their large‐scale applications or require additional surface passivation. The situ passivation phase formation during synthesis can develop heterostructure of nanocrystals with moieties while enhancing facilitating photoreduction reactions stabilizing intermediates due to its chemistry. In this study, two structures perovskite dots, CsPbBr 3 embedded Cs 4 PbBr 6 composite structures, prepared through flow chemistry route adjusting operational parameters. nanostructures evaluated atmosphere study for carbon dioxide (CO 2 )photoreduction, where the edge remains relatively unchanged. Ambient Pressure X‐ray Photoelectron Spectroscopy (APXPS) provides direct evidence improved CO adsorption activation, as well alteration intermediate species, highlighting role characteristics promoting reduced products CsPbBr3‐Cs4PbBr6 structure compared individual .
