Abstract

This paper provides a comprehensive overview of high-entropy oxides (HEOs) and their applications in photocatalysis. The unique functionality of HEOs stems from their distinct crystal and electronic structures, achieved through the substitution of one cation with multiple cations in the lattice. This structural innovation has attracted significant attention, with increasing studies since 2019. To date, approximately 38 papers on HEOs in photocatalysis have been reported, indicating that this research is still in its early stages. Some HEOs exhibit photocatalytic performance comparable to that of conventional oxides like TiO₂ and SrTiO₃, highlighting their potential. This Perspective discusses the synthesis methods, crystal structures, and photocatalytic properties of HEOs, emphasizing their advantages through specific examples. Additionally, it proposes future research directions, including the development of innovative materials and prediction of properties using first-principles calculations and machine learning, to advance the application of HEOs in photocatalysis.

高熵氧化物光催化研究进展

本文综述了高熵氧化物（HEOs）及其在光催化中的应用。HEOs的独特功能源于其独特的晶体和电子结构，通过在晶格中用多个阳离子取代一个阳离子来实现。自2019年以来，这一结构性创新引起了广泛关注，相关研究越来越多。迄今为止，大约有38篇关于heo光催化的论文被报道，这表明这项研究仍处于早期阶段。一些HEOs表现出与传统氧化物如TiO2和SrTiO3相当的光催化性能，突出了它们的潜力。本展望讨论了氢氧烷的合成方法、晶体结构和光催化性能，并通过具体实例强调了氢氧烷的优点。此外，它提出了未来的研究方向，包括创新材料的开发和使用第一性原理计算和机器学习的性质预测，以推进heo在光催化中的应用。
