Research progress and perspectives on photocatalysts based on the lead-free double halide perovskite

Abstract

Photocatalytic technology stands as a promising solution to address the current energy and environmental challenges. Halide perovskites, particularly lead-free double halide perovskites, have garnered recognition as next-generation photocatalysts due to their adjustable bandgap, low binding energy, broad visible light absorption range, and efficient charge carrier transfer. In this review, we explore the utilization of lead-free double halide perovskites characterized by their non-toxic attributes and diverse chemical compositions and properties as photocatalysts for both hydrogen production and carbon dioxide reduction. We commence by presenting an overview of lead-free double halide perovskites, followed by a comprehensive analysis of recent research outcomes pertaining to their application as photocatalysts for hydrogen production and carbon dioxide reduction. Lastly, we discuss the challenges and prospects associated with lead-free double halide perovskite photocatalysts. This review is anticipated to serve as a valuable reference for the development of lead-free double halide perovskite-based photocatalysts, addressing critical aspects in the pursuit of achieving high-efficiency hydrogen generation and carbon dioxide reduction, crucial for our future energy and environmental needs.
