Spatial confinement of organic pollutants and reactive oxygen species (e.g., SO4•– •OH) with ultrashort lifetime inside the scale chemical theoretical diffusion could provide a greatly promising strategy to overcome limitation mass transfer in heterogeneous Fenton-like oxidation process. Herein, we first reported spatial cobalt nanoparticles N-doped carbon nanorods (Co-NCNRs), by encapsulating Co into nanorods, activating CaSO3 for antibiotic degradation. Compared Na2SO3 NaHSO3, slowly persistently discharge SO32– due its low solubility, thus avoiding depletion generated SO3•– •OH under high concentration sulfite ions. Fully physical characterizations confirmed that 3D hydrogel was mostly transformed nanorod structure Co-NCNRs at 550 °C. atoms were successfully nanoconfined which contributes prevents agglomeration nanoparticles, enhancing catalytic activity stability water decontamination. The performance, kinetic research, influences inorganic anions, pH, degradation mechanism chlortetracycline catalyzed Co-NCNRs/CaSO3 system have been studied detail. This work not only proposed facile method synthesis catalyst but also provided an excellent wastewater treatment.

One of the most challenging problems for people around world is lack clean water. In past few decades, massive discharge emerging organic pollutants (EOPs) into natural water bodies has exacerbated this crisis. Considerable research efforts have been devoted to removing these EOPs due their biotoxicity at low concentrations. Heterogeneous photocatalysis via coupling clay minerals with nanostructured semiconductors proven be an economical, efficient, and environmentally friendly technology elimination in drinking watershed Natural zeolite (especially clinoptilolites) are regarded as appropriate supports semiconductor-based photocatalysts characteristics having a cost, environmental friendliness, easy availability, co-catalysis, etc. This review summarizes latest on clinoptilolites used prepare binary ternary metal oxide or sulfide hybrid photocatalysts. Various preparation methods composite degradation efficiencies target contaminants introduced. It found that good catalytic activity photocatalyst could attributed synergistic effect combining clinoptilolite adsorbent semiconductor catalyst heterogeneous system, which endow composites excellent adsorption capacity produce more e−/h+ pairs under suitable light irradiation. Finally, we highlight serious threat ecological environment propose current challenges limitations, before putting mineral practice. The present work would provide theoretical basis scientific support application zeolite-based degrading EOPs.
