The purpose of this work was to consider the decolorization efficiency reactive yellow 160 (Ry-160) dye utilizing cobalt aluminum oxide (AlCo2O4)-anchored Multi-Walled Carbon Nanotubes (AlCo2O4/MWCNTs) nanocomposites as catalysts for first time in a photocatalytic process under natural sunlight irradiation. compositional, morphological, and functional group analyses AlCo2O4 AlCo2O4/MWCNTs were performed by Energy Dispersive Spectroscopy (EDS), Field Emission Scanning Electron Microscopy (FE-SEM), Fourier Transform Infrared (FTIR) Spectroscopy, respectively. A UV-Vis (UV-Vis) spectrophotometer used investigate degradation efficiency. results exhibited reduction optical bandgap from 1.5 1.3 eV compared with pure spinel nanocomposites. showed excellent behavior, around 96% Ry-160 observed just 20 min sunlight, showing first-order kinetics rate constant 0.151 min−1. outstanding stability reusability maintaining more than 90% even after seven successive operational cycles. betterment behavior owes first-rate storage capacity electrons MWCNTs, due which catalyst became an electron acceptor. Furthermore, permeable structure MWCNTs greater surface area leading onset active sites, and, turn, it also boosts conductivity reduces formation agglomerates on catalysts, inhibits e−/h+ pair recombination. Concisely, synthesis novel fast activity aim study.

Doping-associated surface modification is a powerful strategy to enhance the photocatalytic potential of n-type semiconductor nanomaterials. Silver (Ag) one most effective dopants that can result in retardation electron hole recombination-generating Schottky barrier at TiO 2 interface with simultaneous extension absorption visible region. This work presents study on effect catechin, bioactive principle polyphenol compound found various plants, synthesis, Ag-doping and stabilization nanoparticles (TiO NPs). The were irregular shape sizes ranging from 19 30 nm. Ag-TiO NPs fabricated using as precursor 1%, 3%, 5% AgNO 3 doping agent. average particle size 1%Ag-TiO NPs, 3%Ag-TiO 5%Ag-TiO was 27.3 ± 7.5 nm, 29.8 9.6 25.0 9.0 respectively. High-resolution transmission microscopy (HRTEM) showed lattice fringes an interplanar spacing 0.23 nm corresponding Ag (111) plane addition presence anatase phase . Fourier transform infrared (FTIR) spectra exhibited broad peak around 400–800 cm −1 attributed Ti-O-Ti stretching vibrations which slightly shifted due changes local bonding environment Ti atoms caused by interactions Ag. Catechin loading between 1.55 3.3 wt. %. superior degradation methylene blue dye up 78%, 87%, 91%, 92%, respectively, RhB 94%, 97% 99%, pseudo-first-order reaction kinetics. Furthermore, its recyclability also demonstrated for three cycles. simplicity fabrication performance here make this green route advantageous environmental applications treat contaminated effluent well numerous other applications.
