Abstract This work describes a new synthetic route for the production of low‐cost and environmentally friendly catalyst: zinc oxide‐based system doped with silver, prepared using novel sol–gel method cassava starch to form gel. The photocatalysts were characterized by different techniques: X‐ray diffraction (XRD), fluorescence spectroscopy (XRF), energy dispersive (EDS), transmission electron microscopy (TEM), photoacoustic (PAS), point zero charge (PZC). XRF EDS results indicated that 2%, 5%, 8%, 10%, silver could be obtained successfully. synthesis employed produced nanoparticles ~30 nm, as confirmed XRD TEM results. band gap values materials (ranging from 1.98 3.05 eV) fall within range suitable catalyst activation under UV radiation. Photocatalytic reactions carried out two emerging pollutants, 2,4‐ d ‐dichlorophenoxyacetic acid (2,4D) caffeine, verify catalytic activity synthesized catalyst. was efficient degradation both pollutants. Tests solar radiation led 100% 2,4D. Cl − ions did not influence process negatively. amount caffeine removed photocatalytic used in ~97% due low material.

Glyphosate, a widely used herbicide, poses significant environmental and health risks due to its persistence in water systems potential carcinogenicity. Effective remediation strategies are critical. This study reviews recent advances the photocatalytic degradation of glyphosate, particularly via use solar visible light-active photocatalysts. These catalysts demonstrate an average efficiency 87.87 %, outperforming UV-active catalysts. Key advancements include hierarchical structures, Z-scheme mechanisms, composite materials, innovations such as doping with transition metals integrating plasmonic materials. approaches have enhanced light absorption, charge separation, overall performance. review also examines reactor designs, immobilized catalyst systems, magnetic photocatalysts, which represent steps toward practical applications. Significant research gaps remain, including need for standardized metrics, comprehensive pathway studies, scalable understanding influence matrix composition on treatment efficiency. The economic feasibility large-scale deployment, stability under real-world conditions, factors performance require further exploration. Future directions optimizing process parameters, exploring hybrid investigating processes natural developing cost-effective synthesis methods. emphasizes importance addressing these challenges develop sustainable efficient glyphosate Comprehensive comparisons between different sources, more studies utilizing real radiation, pilot-scale experiments essential advance application technologies. Furthermore, interdisciplinary collaboration will be key overcoming challenges.
