光催化技术因其绿色、可持续和低成本的反应过程被认为是解决能源危机和环境污染的有效方法.光催化技术发展的核心挑战是高性能光催化剂的开发, 因此高效催化材料的设计与制备始终是本领域的研究核心. 截至目前, 研究人员已经开发了不同类型的半导体光催化剂, 如金属氧化物、硫化物、氮化物和铋基材料. 这些材料通常具有独特的电子结构、稳定的性能、简便的制备路线和较低的制备成本. 然而, 未改性的半导体材料普遍面临活性位点不足、可见光捕获能力弱、光生载流子复合严重等瓶颈, 导致光催化活性低下, 从而阻碍了该技术的实际应用.
本文系统地综述了原子空位缺陷在半导体光催化太阳能燃料制备和高价值化学品生产中的关键作用, 包括增强可见光响应能力、调节电子带隙结构、降低活化能、促进反应物分子的吸附和活化以及提高催化剂稳定性. 同时, 详细介绍了目前原子空位缺陷的相关先进表征, 包括电子显微镜、X射线衍射技术、X射线光电子能谱、电子顺磁共振技术、拉曼光谱、同步辐射吸收光谱等. 概括了一些常用的策略(化学合成、物理合成、机械方法、电化学合成法)用于制备原子空位缺陷型光催化剂. 分析对比了这些缺陷合成方法的优势和劣势. 随后, 列举了一系列先进的原子空位缺陷型半导体光催化剂用于水分解以产生绿色氢气和氧气, 以及将二氧化碳还原为增值燃料和化学品, 如一氧化碳、甲烷、甲醇和乙醇等. 这种光催化能源转化技术能够有效地将丰富的太阳能储存在液体燃料和化学品中, 减少二氧化碳排放, 为可再生能源存储技术提供了一种有前景的解决方案. 除了太阳能燃料制备外, 文章还讨论了缺陷光催化剂用于一些高附加值的化学品(如H2O2和NH3)的高效制备. 概述了利用含原子空位光催化剂进行光化学太阳能燃料和增值化学品生产的优势之处. 最后, 对原子空位缺陷型半导体光催化剂的大规模商业化应用前景和关键科学问题进行了展望.
综上, 本综述总结了原子空位缺陷型半导体光催化剂的优势、研究进展、合成策略、表征方法、能源转化应用以及大规模生产存在的挑战, 希望通过推动科研人员进一步思考和探索推动原子空位缺陷半导体光催化在太阳能燃料制备和高价值化学品生产中的实际应用, 为实现双碳目标提供一定的借鉴.
