Treffer: High-Entropy Materials for Photocatalysis: A Mini Review.

In recent years, high-entropy materials (HEMs) have emerged as a promising multifunctional material system, garnering significant interest in the field of photocatalysis due to their tunable microstructures, diverse compositions, and unique electronic properties. Owing to their multi-element synergistic effects and abundant active sites, high-entropy photocatalysts enable precise regulation over the separation efficiency of photo-generated charge carriers and surface reaction pathways, thereby significantly enhancing photocatalytic activity and selectivity. The high configurational entropy of these materials also imparts exceptional structural stability, allowing the catalysts to maintain long-term durability under harsh conditions, such as intense light irradiation, extreme pH levels, or redox environments. This provides a potential alternative to common issues faced by traditional photocatalysts, such as rapid deactivation and short lifespans. This review highlights recent advancements in the preparations and applications of HEMs in various photocatalytic processes, including the degradation of organic pollutants, hydrogen production, CO<subscript>2</subscript> reduction and methanation, H<subscript>2</subscript>O<subscript>2</subscript> production, and N<subscript>2</subscript> fixation. The emergence of high-entropy photocatalysts has paved the way for new opportunities in environmental remediation and energy conversion. [ABSTRACT FROM AUTHOR]
