ABSTRACT With a wide range of development opportunities, photocatalytic technology provides potent solution to today's energy and environmental issues. In this study, tin‐doped copper oxide nanoparticle loaded on almond shell activated carbon (Sn: CuO/ASAC) were prepared thoroughly examined described using UV‐DRS, XRD, BET, FT‐IR, SEM with EDS, XPS. Band gap was decreased visible absorbance increased as result Sn‐doping ASAC loading. Therefore, by altering batch experimental conditions such starting pH the quantity Sn‐doped CuO composite, all product samples employed for MB dye degradation from aqueous under sunlight. The obtained results revealed that >99.37% removal over composite sample achieved within 90 min 1.2 g L −1 adsorbent dosage, 40‐mg/L at weakly alkaline values. kinetics study accurately describes rates, revealing high rate constant 0.052 compared other samples. mechanism studied radical scavenging tests Sn: CuO/ASAC. These findings suggested could be considered wastewater treatment technique.
