Application of Metal Halide Perovskites as Photocatalysts in Organic Reactions

Abstract

This review summarizes the current status of the application of metal halide perovskites (MHPs) as photocatalysts in organic syntheses/transformations. It is shown that the optimal and unique electronic properties of MHPs can be advantageously used in several reaction types providing pros with respect to traditional photocatalysts. While still being at infancy, such field of application of MHPs as effective photocatalysts will for sure become a central research topic in the forthcoming years, thanks also to their rich structural and chemical tunability, which may provide tailored materials for most of the envisaged organic reactions.

Anion Exchange in Lead Halide Perovskites: An Overview

“…[93,99] Several organic transformations can be carried out under visible light in presence of lead halide perovskites as photocatalysts. [100,101] Lead halide perovskites also find applications in the field of photocatalytic degradation of persistent toxic organic compounds in polluted water. [91,102] The halide ion vacancy in the surface of the lead halide perovskites are known to enhance the photocatalytic property.…”
