Increasing demand for food due to rapid population growth has exerted unprecedented pressure on the global agricultural industry. Agrochemicals are widely used to ensure productivity, leading to the prevalence of legacy and emerging agricultural chemicals in the environment, most of which are toxic and persistent. Metal–organic frameworks (MOFs) as a group of novel photocatalytic materials with ultrahigh porosity and tunability have demonstrated high potential for efficient removal of these recalcitrant pollutants. This critical review aims to present the potential of MOF-catalyzed photodegradation of pesticides and antibiotics. Initially, the capabilities of different MOF-based composites to harvest visible light are compared. Examples include MOFs combined with bismuth oxyhalides (BiOX) and graphite oxide (GO). Mechanisms involved in MOF-induced photocatalytic processes such as electron–hole (e/h+) separation, generation of reactive species, and degradation pathways of representative pollutants as well as impacts of water chemistry are illustrated in detailed. Research on applying MOF-catalyzed processes is largely in progress, and many more studies with greater mechanistic evaluation are needed to fully assess the potential of such processes to depollute water.

金属有机框架(MOF)作为光催化剂降解水中的农业污染物

由于人口的快速增长,对食品的需求增加对全球农业产生了前所未有的压力。农药广泛用于确保生产率,从而导致环境中遗留的和新兴的农业化学品普遍存在,其中大多数是有毒且持久的。金属有机框架(MOF)作为一组具有超高孔隙率和可调性的新型光催化材料,已显示出有效去除这些难降解污染物的巨大潜力。这项重要的评论旨在介绍MOF催化的农药和抗生素光降解的潜力。最初,比较了基于MOF的不同复合材料收集可见光的能力。示例包括与卤氧化铋(BiOX)和氧化石墨(GO)结合的MOF。 / h +)的分离,反应性物种的产生,代表性污染物的降解途径以及水化学的影响进行了详细说明。应用MOF催化工艺的研究正在进行中,需要进行更多的机械评估研究以充分评估此类工艺对水的去污能力。
