Recent Progress and Perspectives on Nonlead Halide Perovskites in Photocatalytic Applications

Abstract

Photocatalysis is a technique and one of the prospective solar-energy-conversion strategies for addressing the current energy and environmental problems. Developing a powerful photocatalyst is the key to achieving a supernal visiblelight-induced catalytic activity. Lead halide perovskites have been broadly utilized in photocatalysis with excellent performance; however, their practical applications and commercial values are extremely limited by intrinsic lead toxicity. Therefore, it is urgent and reasonable to substitute Pb with other harmless elements in halide perovskites, which has recently boomed as an attractive research field. The substitute candidates are Sn (same main group as Pb), Bi (same period as Pb), Sb, and other transition metal elements. In this review, we first give a systematic introduction to the structure and characteristics of nonlead halide perovskites. The following section provides a general description of the preparation methods and photocatalytic performance for nonlead halide perovskites. Finally, the prospects and challenges of nonlead halide perovskites in the photocatalytic field are discussed, which may facilitate and guide the future investigation of this exciting topic.

CO2 to solar fuel: design and reactivity of inorganic perovskites

“…To enhance the photocatalytic activity in the CO 2 reduction reaction and tackle the stability limitations, several synthesis methods have been developed. The most common methods are presented as follow [42,50].…”

“…The temperature and the auto-generated pressure due to the evaporation of the solvent facilitate the crystal nuclei formation. The relatively low temperature (100 • C-180 • C) employed in these methods is a significant advantage against other synthetic processes [50,59]. The morphology of the synthesized material can be easily controlled by modification of the reaction time, temperature or the type of ligand used as the capping agent [60,61].…”

Accordingly, this minireview summarizes the synthesis methods and physical–chemical properties of BHPs, with a focus on the fabrication of BHP nanomaterials with various micro-morphologies, band structures and surface chemical environment.…”

Lead‐Free Halide Perovskite Photocatalysts for Photocatalytic CO2 Reduction: A Review

“…[ 26–32 ] Although there have been some reviews on lead‐free perovskite photocatalysts, however, there is no systematic analysis of photocatalytic CO 2 reduction by lead‐free perovskite. [ 33–35 ] Therefore, this review focuses on the research progress of lead‐free perovskite for photocatalytic CO 2 reduction. The mechanism of the photocatalytic CO 2 reduction system, reaction kinetics, CO 2 adsorption, and the reaction pathway, which affects product selectivity, are introduced at first.…”
