The presence of heavy metal ions and emerging pollutants in water poses a great risk to various biological ecosystems as a result of their high toxicity. Consequently, devising efficient and environmentally friendly methods to decontaminate these waters is of high interest to many researchers around the world. Among the varied water treatment and desalination means, adsorption and photocatalysis have been widely employed. However, the discussion and analysis of the use of zeolite-based composites as adsorbents are somehow minimal. The porous aluminosilicates (zeolites) are excellent candidates in wastewater treatment owing to various mechanisms of pollutants removal that they possess. The purpose of this review is thus to provide a synopsis of the current developments in the fabrication and application of nanocomposites based on zeolite as adsorbents and photocatalysts for the extraction of heavy metals, dyes and emerging pollutants from wastewaters. The review goes on to look into the effect of weight ratio on photocatalyst, photodegradation pathways, and various factors that influence photocatalysis and adsorption.
水中重金属离子和新兴污染物的存在因其高毒性对各种生物生态系统构成了极大的风险。因此，设计高效、环保的方法来净化这些水是全世界许多研究人员的关注重点。在各种水处理和脱盐方法中，吸附和光催化得到了广泛应用。然而，沸石基复合材料作为吸附剂的使用讨论和分析却有些不足。多孔铝硅酸盐（沸石）是废水处理的优良候选材料，因为它们具有多种污染物去除机制。因此，本综述的目的是概述沸石基纳米复合材料作为吸附剂和光催化剂的制备和应用的最新进展，用于从废水中提取重金属、染料和新兴污染物。综述还探讨了重量比对光催化剂、光降解途径的影响，以及影响光催化和吸附的各种因素。
