Pesticides and organic waste constitute a group of environmental pollutants that are widely distributed in our environment due to various human activities. Adsorptive removal and photocatalytic degradation of these pollutants from water have emerged as energy and cost-effective technologies. However, advanced oxidation technologies are gaining attention as an effective method for wastewater treatment capable of degrading a diverse spectrum of organic contaminants. Photocatalysis is a promising advanced oxidation technology to alleviate water pollution problems. Titanium dioxide (TiO₂) is the most popular photocatalyst due to its low cost, nontoxicity, high oxidizing abilities, and easy immobilization on various surfaces. The current review aims to highlight recent advancements in photocatalytic degradation of pesticides and major organic pollutants using TiO₂-based photocatalysts. Indeed, most of the methods, which employed potent catalysts, showed and exhibited successful degradation of the pesticides under various conditions. We believe this topic of research is extremely vital and will continue to grow in recent years, reaching ultimate desirable results and find more applications in different fields of study.

农药和有机废物构成了一组环境污染物，由于人类的各种活动而广泛分布在我们的环境中。从水中对这些污染物的吸附去除和光催化降解已经成为能源和具有成本效益的技术。但是，作为一种能够降解多种有机污染物的有效废水处理方法，先进的氧化技术正受到关注。光催化是缓解水污染问题的一种有前途的先进氧化技术。二氧化钛（TiO ₂由于其低成本，无毒，高氧化能力以及易于固定在各种表面上，因此是最受欢迎的光催化剂。本综述旨在突出使用基于TiO ₂的光催化剂在农药和主要有机污染物的光催化降解方面的最新进展。实际上，大多数使用有效催化剂的方法在各种条件下均显示并显示出农药的成功降解。我们认为，这一研究主题至关重要，并将在近年来继续增长，达到最终的理想结果，并在不同的研究领域中找到更多的应用。
