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.

Tests solar radiation led 100% 2,4D. Cl − ions did not influence process negatively. amount caffeine removed photocatalytic used in ~97% due low material.

Water pollution poses a severe threat to both aquatic ecosystems and human health, highlighting the crucial importance of monitoring regulating its levels in water bodies. In contrast traditional single-treatment approaches, multiple-treatment methods enable simultaneous detection removal pollutants using single material. This innovation not only offers convenience but also fosters more holistic effective approach remediation. Metal–organic frameworks (MOFs) are versatile porous materials that offer significant potential for use wastewater treatment. article examines latest developments application MOFs multifaceted used removal, or degradation contaminants. Some exhibited different functions contaminants, some showed one function (adsorption detection) than contaminant. All multifunctional facilitate multiple treatment real wastewater. Lastly, existing challenges future outlooks concerning MOF addressed this paper.

Abstract The primary objective of this study was to create and analyze a new type LaFeO 3 /methylcellulose/multi-walled carbon nanotubes-NiCu 2 O 4 /Zn nanocomposite, called LFO/MC/MWCNT-NCO/Z, which has multiple functions. Structural investigation using field emission scanning electron microscopy showed that the nanoparticles (40–50 nm) were evenly distributed throughout suggesting they successfully incorporated without any clumping. FTIR research verified existence functional groups facilitate electrostatic interactions with contaminants, hence strengthening catalytic performance improving adsorption efficiency. BET analysis revealed significantly high specific surface area 72.61 m /g, greatly enhances its ability adsorb substances. nanocomposite demonstrated removal efficiency in (74.55%), photocatalysis (68.19%), sonocatalysis (91.22%) procedures, highlighting potential for effectively removing bisphenol A as organic pollutants. synthesized LFO/MC/MWCNT-NCO/Z shows great eliminating contaminants from water solutions. This offers sustainable way address pollution protect human health environment.
