| چکیده مقاله |
| Advanced oxidation processes (AOPs) effectively degrade and mineralize recalcitrant organic pollutants via in situ generation of powerful ROS, especially SO₄•⁻ and OH•. Sulfate radical-based AOPs using peroxydisulfate (PDS) activation have recently gained prominence due to the higher oxidation potential, longer half-life, and broader pH tolerance of SO₄•⁻ compared to OH• [1]. Integrating biomass derived activated carbon with bimetallic MOFs creates synergistic heterogeneous catalysts that offer excellent MOF dispersion, abundant active sites, efficient PDS activation, superior catalytic performance, high reusability, and enhanced environmental sustainability[2]. In this project, the Co–Fe MOF/biochar nanocomposite was prepared by a two-step co-precipitation method. Initially, pine needle-derived biochar was dispersed in an aqueous K₃[Co(CN)₆] solution. Subsequently, an aqueous solution of Co(NO₃)₂·6H₂O was rapidly added under vigorous stirring. The resulting mixture was further aged, and the obtained precipitate was collected by centrifugation, thoroughly washed several times with deionized water, and finally dried. The as-prepared nanocomposite exhibited excellent catalytic performance in peroxydisulfate-based advanced oxidation reactions due to the synergistic effect between the Co–Fe Prussian blue analogue and the biochar support. |
