Rational engineering and fabrication of efficient nanophotocatalysts based on ZnO-SrO-CdS for pharmaceutical pollutants based wastewater degradation

Highly Selective Pb(II) Adsorption by DTPA-Functionalized Graphene Oxide/Carboxymethyl Cellulose Aerogel

“…Conventional adsorbents encompass a range of well-established substrates such as activated carbon, zeolite, chitosan, and biochar, each renowned for their distinct sorption properties and applicability. In contrast, emerging materials constitute a diverse array of innovative substrates including nanomaterials and photocatalytic , materials, characterized by their unique physicochemical attributes and promising adsorption capabilities. A layered double hydroxide composite material with a maximum adsorption capacity of 423.73 mg/g for Cr­(VI) and 588.24 mg/g for CR was prepared by Eltaweil et al However, traditional adsorbents are usually in powder or granular form with poor separability and recoverability, making wastewater treatment costly.…”

A Review of Synthesis Methods, Modifications, and Mechanisms of ZnO/TiO2-Based Photocatalysts for Photodegradation of Contaminants

“…General applications of ZnO and TiO 2 are as photocatalysts for the photodegradation of organic and inorganic pollutants, electrodes for water splitting, H 2 production, CO 2 reduction, solar cells, support of drug delivery, sensors, , and energy storage. , These compounds act as n-type semiconductor photocatalysts for the degradation of a wide range of organic pollutants from air to wastewater domains. TiO 2 crystallizes in three structures: (1) anatase, (2) rutile, and (3) brookite, with Ti 4+ in the center and six oxides in an octahedral arrangement.…”
