摘要

光催化通常被认为是缓解全球能源和环境挑战的最重要的技术。特别是，基于半导体的光催化剂作为一种超越当前传统技术限制的方法而引起了更多的兴趣。这些光催化材料继续遭受高重组率，光吸收，稳定性和耐久性差，这限制了它们的商业可行性。有几种策略用于解决这些问题。其中，通过缺陷工程在光催化材料中制造氧空位（OVs）已成为一种具有成本效益的缩蛋策略，可以增加可见光吸收，并在不重组的情况下分离和转移载流子。本文综述了光催化剂中光阱的概念及其用途。此外，本文还讨论了多种有效地在材料中生产OVs以提高工艺效率的方法。此外，它还涵盖了某些检测技术，以验证特定材料中氧空位的存在。概述了OVs在污染降解、制氢、CO2还原和固氮等方面的应用，为解决环境问题提供了潜在的研究方向。

Engineering the role of oxygen vacancies in photocatalysts for environmental remediation and energy conversion applications: A comprehensive review

Photocatalysis is often regarded as the most significant technology for mitigating global energy and environmental challenges. In particular, semiconductor-based photocatalysts have drawn more interest as a way to get beyond the constraints of the current conventional techniques. These photocatalytic materials continue to suffer from high recombination rates, poor light absorption, stability, and durability, which limit their commercial viability. Several strategies are used to address these problems. Among them, creating oxygen vacancies (OVs) in photocatalytic materials by defect engineering has been appeared as a cost-effective Eg-narrowing strategy for increasing visible light absorption and separating and transferring charge carriers without recombination. The idea of OVs in a photocatalyst and their purposes are highlighted in this review. In addition, it discusses the many methods for effectively producing OVs in a material to improve process efficiency. Additionally, it covers the certain detection techniques to verify the existence of oxygen vacancies in a specific material. Besides, the utilization of OVs in pollution degradation, hydrogen production, CO₂ reduction, and N₂ fixation are outlined to offer potential research direction to address the environmental issues.
