Biosynthesis of CoCrO/ZnO nanocomposites using Basella alba L. leaves extracts with enhanced photocatalytic degradation of malachite green in aqueous media.

The use of chemical materials to tackle environmental concerns has undergone significant evolution, particularly in the pursuit of strategies for removing pollutants from wastewater as part of environmental remediation an increasingly crucial research topic. Employing green photocatalysts stands out as an efficient and cost-effective approach, playing a key role in promoting sustainable environmental remediation. This study introduces the modification of zinc oxide with cobalt chromite (CoCrO/ZnO) through a green synthesis method employing Basella alba L.

SmMnO-decorated ZnO in a hexane-water interface for enhancing visible light-driven photocatalytic degradation of malachite green.

Malachite green (MG) contributes to water contamination because its accumulation adversely impacts aquatic systems. For the first time, we prepare a high photoresponse of ZnO/SmMnO heterojunction via a high-speed stirring method at the nonpolar-polar interface assisted by Alstonia scholaris leaves extract (ASLE) as natural hydrolyzing and stabilizing agents. The heterojunction formation boosts the photocatalytic activity of ZnO up to 91.
