| Summary: | Over the last few years, the generation of wastewater has been increased due to the growth of industry and population. Wastewater, if not treated properly, can leave a negative impact on the environment and human health. These impacts mainly include adverse effects on aquatic life, wildlife, and contamination of drinking water which can further lead to diseases such as diarrhea, jaundice, and extreme carcinogenic and oncogenic effects. Various chemical, biological, and physical methods, such as adsorption, ultrafiltration, electrodialysis, photocatalysis, and biofiltration, have been used for wastewater treatment. Zeolites have been recognized as a useful adsorbent for wastewater remediation. Though the photocatalytic activity of zeolites has not been much explored yet, however it can be explored as a potential photocatalyst. Incorporating zeolites with various semiconducting nanoparticles, the photocatalytic activity of zeolite-based nanocomposites can be improved. The resulted novel material may possess enhanced photocatalytic and adsorption properties and may prove an efficient photocatalyst for the degradation of organic pollutants from wastewater. This report represents the synthesis and use of zeolites and zeolite-based materials for wastewater treatment which have been demonstrated to date. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.
