目前的批判性审查报告了过去 10 年在非均相光催化转化生产高附加值有机产品方面取得的进展，这些产品有可能为许多重要的工业化学品提供绿色合成路线。大多数注意力集中在光催化剂存在下有机化合物的氧化和还原。还考虑了生物质的转化。由于二氧化钛在紫外线照射下具有光活性、在常用反应条件下具有稳定性和高表面积，因此二氧化钛是目前最丰富的光催化材料。尽管在光催化领域取得了明显的成就，但 TiO ₂最显着的局限性是不同晶相的带隙很大，这使得仅使用紫外线照射来启动光催化过程成为可能。为了有效利用太阳能，开发对可见光敏感的新型光催化剂是多相光催化理论和实践的重要方向。在这方面，这篇批判性评论的一个特别重点是金属-有机骨架在光催化反应中的使用，因为它们在组成、结构和功能特性方面具有灵活的可调性，已成为一类有趣的应用于有机光反应的材料。，促进对化学品的吸附和有效的光吸收。

Application of metal–organic frameworks as an alternative to metal oxide-based photocatalysts for the production of industrially important organic chemicals

The present critical review reports progress over the last 10 years in the heterogeneous photocatalytic conversion to produce value-added organic products that have the potential to provide a green synthesis route for a number of industrially important chemicals. Most attention has been paid to the oxidation and reduction of organic compounds in the presence of photocatalysts. There has also been consideration of the conversion of biomass. Nowadays, titanium dioxide is the most abundant photocatalytic material due to its photoactivity under ultraviolet illumination, stability under commonly used reaction conditions and high surface area. Despite obvious achievements in the field of photocatalysis, the most significant limitation of TiO₂ is its large band gap for different crystalline phases, which makes it possible to use only ultraviolet illumination to initiate photocatalytic processes. With a view to efficient solar-energy utilisation, the development of new photocatalysts, which are sensitive to visible light, is an important direction in the theory and practice of heterogeneous photocatalysis. In this regard, a special focus of this critical review is on the use of metal–organic frameworks in photocatalytic reactions because they have emerged as an interesting class of materials for applications in organic photoreactions due to their flexible tunability in composition, structure and functional properties, facilitated adsorption towards chemicals, and efficient light absorption.
