Halide Perovskite Materials for Photo(Electro)Chemical Applications: Dimensionality, Heterojunction, and Performance
ADVANCED ENERGY MATERIALS(2022)
Abstract
In recent years, halide perovskite materials have sparked intensive research, including their burgeoning development in the field of photo(electro)chemical catalysis. Halide perovskite materials are based on abundant and low-cost elements with a rich structural composition and a variety of molecular and morphological dimensionalities. They possess versatile advantages over other photo(electro)catalytic materials owing to the facile adjustment of electronic properties via molecular and compositional engineering. Thus, the rapid development of perovskite photo(electro)catalysts in the past 4-5 years has opened up new opportunities for diverse photo(electro)chemical applications, ranging from photocatalytic organic reactions (e.g., chemical transformations, photopolymerization, and degradation) to solar-to-chemical fuel conversion (e.g., water splitting and CO2 reduction). This review aims to provide an up-to-date discussion on recent applications of halide perovskite photo(electro)catalytic materials, emphasizing their crystal and morphological dimensionality, synthetic methodologies, heterojunction structures, and fundamental structure-activity relationships. Furthermore, current challenges and future research directions for the rational design of halide perovskite materials to boost their overall catalytic performance and stability are identified and envisaged respectively.
