Mesoporous spongy Ni–Co oxides@wheat straw-derived SiO2 for adsorption and photocatalytic degradation of methylene blue pollutants

The exploitation and employment of agricultural waste in polluted water treatment are one the most important cost-effective approaches. Therefore, a novel mesoporous spongy adsorbent/photocatalyst was successfully synthesised through grafting nickel cobalt oxides nanocomposites with wheat straw-derived SiO2 (WSS). Nickel were added to enhance functionality SiO2. This synthesis methodology presents simplistic, cost-effective, eco-approachable alternative getting an adsorbent photocatalyst for adsorption photocatalytic degradation methylene blue (MB) pollutants from wastewater. modified (MWSS) characterised via XRD, SEM, EDX, TGA, FTIR, nitrogen adsorption. Molecular dynamics computational calculations performed comprehend ability adjust MWSS surface. photodegradation trials optimise pH, contact time, initial MB concentration, temperature parameters. optimum removal conditions as follows: pH 10, dose 50 mg, time 45 min, 25 ± 2 °C, UV lamp (70 W) process. obtained data indicated that provided efficient capability (79%), significant performance (93%), higher solidity during reusability well. Furthermore, kinetics isotherm models checked explain mechanism using MWSS. study suggests composite contributes rid
