Perovskite-based materials have become a new direction for peroxymonosulfate (PMS) activation in pollutants degradation. However, the mechanism towards PMS remains insufficient. In this paper, series of LaMxMn1−xO3 with B-site doping were developed by sol-gel self-propagating combustion method. The prepared LaFe0.3Mn0.7O3/PMS system exhibited desired catalytic activity, almost 100% removal efficiency TC can be achieved within 50 min and 98% initial activity could maintained after 5 cycles. Quenching experiments EPR tests together certified vital roles •O2− 1O2 during degradation procedure. Simultaneously, performance was examined relation to varying pH values, coexisting chemicals, water conditions. DFT calculations demonstrated an increased electron concentration reactive sites Fe doping. addition, LaFexMn1−xO3 at electron-rich state bond strength O atoms encouraged adsorption/desorption intermediates process. aforementioned outcomes showed possibility application intricate, realistic aquatic environments.

Abstract The photocatalytic decomposition rates of a widely used nonsteroidal anti-inflammatory drug naproxen wastewater were assessed using Ca3Co4O9 and Sc-doped /Chitosan nanocomposit films as photocatalyst irradiating with visible light. Chitosan was extracted from shrimp shells an immobilization matrix for the prepared photocatalyst. synthesized Pechini method composites characterized FTIR, XRD, TEM optical properties. Naproxen chosen model compound pharmaceutical to determine performance nanocomposite films. % removal attained 95% chitosan/Ca3Co3.99Sc0.01O9, photodegradation followed pseudo-first-order kinetics. To gain extensive comprehension process, key active species involving (50/50) chitosan/ Ca3Co3.99Sc0.01O9 also investigated. Various scavengers incorporated into degradation process block potential superoxide radicals ( \(\:{O}_{2}^{\cdot\:}\)), photoexcited holes (h+), hydroxyl (⋅OH) fulfill this target. Removal COD, BOD, TOC in real samples exceeded 85%. Even after five cycles, film's reusable properties demonstrated continuous capabilities, only 10% loss. investigation utilized two-level factorial design that included diagnostic plots such perturbations plot, ANOVA, Pareto's chart.
