摘要：

利用太阳能驱动的光催化技术，有望成为缓解环境和能源压力的可行策略。因此，光催化性能的优异与否取决于光催化剂的合理设计。通过考虑形貌调控、带隙工程、助催化剂修饰以及异质结构建等因素，可以开发出性能优异的光催化剂。基于中空结构光催化剂独特特性的启发，具有中空结构的光催化剂在光催化剂设计中赋予了诸多优势，包括增强光的多重折射和反射、缩短光生载流子的传输距离以及提供丰富的表面反应位点。在此，我们系统地回顾了中空结构光催化剂的最新研究进展，并总结了其几何形貌、内部结构和化学成分的多样性。具体而言，我们重点介绍了中空结构光催化剂的合成策略，包括硬模板法、软模板法和无模板法。此外，还详细总结了一系列中空结构光催化剂，如金属氧化物、金属硫化物、金属有机框架和共价有机框架等。随后，我们概述了中空结构光催化剂在光催化污染物降解、H2生成、H2O2生成、CO2还原和N2固定等领域的潜在应用。同时，深入探讨了中空结构与光催化性能之间的内在关系。最后，我们分析了中空结构光催化剂未来发展方向中的挑战和前景。该综述为更好地设计中空结构光催化剂以满足环境修复和能源转换需求提供了启示。

Abstract:

Photocatalysis technology, utilizing solar-driven reactions, is poised to emerge as a reliable strategy to alleviate environmental and energy pressures. Thus, whether the photocatalytic performance is excellent depends on the reasonable design of photocatalysts. By considering factors such as morphology engineering, band gap engineering, co-catalyst modification, and heterojunction construction, the photocatalysts with superior performance can be developed. Inspired by this unique characteristic, photocatalysts with a hollow structure endow numerous advantages in photocatalyst design, including enhanced multiple refraction and reflection of light, reduced transport distance of photo-induced carriers, and provided plentiful surface reaction sites. Herein, we systematically review the latest progress of hollow structured photocatalysts and summarize the diversity from geometric morphology, internal structure, and chemical composition. Specifically, the synthetic strategies of hollow structured photocatalysts are highlighted, including hard template, soft template, and template free methods. Furthermore, a series of hollow structured photocatalysts have also been described in detail, such as metal oxide, metal sulfide, metal-organic framework, and covalent organic framework. Subsequently, we present the potential applications of hollow structured photocatalysts in photocatalytic pollutant degradation, H2 production, H2O2 production, CO2 reduction, and N2 fixation. Simultaneously, the relevant relationship between hollow structure and photocatalytic performance is deeply discussed. Toward the end of the review, we introduce the challenges and prospects in the future development direction of hollow structured photocatalysts. The review can provide inspiration for better designing hollow structured photocatalysts to meet the needs of environmental remediation and energy conversion.
