Method & Evidence

AimHow can porous geopolymer spheres with in-situ grown CuO be optimized to enhance peroxymonosulfate activation for the efficient degradation of organic pollutants in water?

MethodExperimental research and chemical analysis

ProcedureResearchers synthesized porous geopolymer spheres and grew copper oxide (CuO) directly onto their surface. They then tested the catalytic performance of these composite spheres in activating peroxymonosulfate (PMS) to degrade Orange I, a model organic pollutant. Various factors influencing the degradation efficiency, such as PMS concentration, catalyst dosage, and the presence of common water impurities, were systematically investigated. Mechanistic studies were conducted to understand the degradation pathways and identify the active species involved.
