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.

This study examines the incorporation of artificial intelligence (AI) technologies in the sectors of tourism and hospitality with the goal of understanding how they influence customer satisfaction and operational effectiveness. To lay the groundwork for a thorough examination of AI-driven developments, the introduction provides an overview of AI technologies and their possible uses in the hospital and tourist industries. The sections that follow focus on particular fields in which artificial intelligence is significantly advancing. Stakeholders in the hospitals and tourist industries may fully utilize AI to produce experiences that are unmatched and have a good social impact by committing to ethical AI deployment, collaborating with partners, and making strategic investments. Achieving remarkable experiences, encouraging sustainability, and propelling industrial expansion are all possible with AI if stakeholders in the hospital and tourist sectors embrace its ethical use, collaborate, and make calculated investments.

Constructing visible-light-active Z-scheme heterojunctions has proven fruitful in enhancing the photocatalytic activity of photocatalysts for superior water clean-up. Herein, we report the fabrication of a CoFe₂O₄@Bi₂O₃/NiO (CBN) Z-scheme nanoheterojunction. The obtained CBN heterojunction was used for visible-light-assisted degradation of ofloxacin (OFL) in water. The OFL degradation efficiency achieved by the CBN heterojunction was 95.2% in 90 min with a rate constant of k_app = 0.03316 min⁻¹, which was about eight times that of NiO and thirty times that of CoFe₂O₄. The photocatalytic activity of a Bi₂O₃/NiO Z-scheme heterojunction was greatly enhanced by the visible activity and redox mediator effect of the cobalt ferrite co-catalyst. Higher charge-carrier separation, more visible-light capture, and the Z-scheme mechanism in the Z-scheme system were the important reasons for the high performance of CBN. The scavenging experiments suggested ^●O₂⁻ as an active species for superior OFL degradation. The possible OFL degradation pathway was predicted based on LC-MS findings of degradation intermediate products. The magnetic nature of the CBN helped in the recovery of the catalyst after reuse for six cycles. This work provides new insights into designing oxide-based heterojunctions with high visible-light activity, magnetic character, and high redox capabilities for potential practical applications in environmental treatment.
