High-entropy materials for photocatalysis

High-entropy materials (HEMs), characterized by their unique compositional diversity and configurational entropy, have emerged as promising candidates in the field of photocatalysis. These materials, typically composed of five or more principal elements, exhibit remarkable structural stability, enhanced electronic properties, and superior resistance to corrosion and oxidation. In the realm of photocatalysis, HEMs offer several advantages, including broad spectral absorption, efficient charge separation, and robust catalytic activity under various environmental conditions. This review summarizes recent advancements in the synthesis, characterization, and application of HEMs for photocatalytic processes, such as H 2 evolution, CO 2 conversion, organic pollutant degradation, and organic conversion. By exploring the intrinsic properties of HEMs and their synergistic effects, we aim to highlight their potential to revolutionize the design and development of next-generation photocatalysts. The integration of HEMs into photocatalytic systems not only paves the way for more efficient and sustainable energy conversion technologies but also opens new avenues for environmental remediation.
