Zinc oxide (ZnO) photocatalysts have emerged as a promising material for environmental and energy applications due to their exceptional photocatalytic properties. Initially recognized efficiency under ultraviolet (UV) light, recent advancements focused on enhancing ZnO’s visible light activity (VLA) address its inherent limitations. This review provides an overview of structure, electronic properties, mechanisms. Various strategies modifying ZnO harness including metal non-metal doping, dye sensitization, semiconductor coupling, are discussed. Special emphasis is placed the mechanisms behind absorption reactive oxygen species (ROS) generation, deduced through physicochemical photoelectrochemical analyses. The in remediation comprehensively explored, particularly water treatment, disinfection, air purification. degradation pollutants, persistent organic compounds, pharmaceuticals, dyes, pesticides, using reviewed compared with conventional UV-activated materials. underscores potential efficient sustainable solution

In this study, iron oxide biochar nanocomposites made from khat leftover (KL) and coffee husk (CH) are investigated as possibly useful adsorbents for the removal of Cr (VI) water. Biochar-based were synthesized by pretreating 25 g biomass with a 1:1 molar ratio FeS to FeCl3 pyrolyzing at 300 °C 1 h. Pristine biochar, through pyrolysis CH KL °C, removed 74.98% 84.78% aqueous solutions containing 20 mg L−1, respectively. The corresponding showed maximum efficiency 99.83% oxide-coffee nanocomposite (Fe3O4–CHBNC) 99.86% oxide-khat (Fe3O4-KLBNC). A pseudo-second-order model Langmuir isotherm both well-fitted adsorption process, suggesting advantageous monolayer adsorption. Fe3O4–CHBNC Fe3O4-KLBNC demonstrated satisfactory efficiencies even up six cycles, indicating their potential effectiveness large-scale use treating wastewater contaminated (VI).
