Special Issue Information

Dear Colleagues,

Global industrialization and urbanization have amplified environmental pollution, posing risks to ecological and human health. As the demand for environmental remediation and the degradation of pollutants in various aquatic systems intensifies, the development of advanced oxidation processes and environmentally friendly catalytic materials has become crucial. These strategies predominantly focus on contaminant removal via oxidation, often necessitating the significant influx of oxidants and the generation of reactive species, such as •OH, SO4, reactive chlorine species, reactive phosphate species, and so on.

Contemporary research encourages the deployment of innovative catalytic processes to mitigate health concerns and curtail the operational expenses associated with chemical additives during aquatic remediation endeavors. Elements, such as inorganic ions, natural organic materials, trace metallic cations, nanoparticles, microplastics, and other inherent environmental substances, can be harnessed to initiate catalytic reactions, targeting the degradation of pollutants, particularly the emerging contaminants. Furthermore, functional materials with expansive surface areas and a good catalytic ability can active oxidants like H2O2, O3, persulfate, peracetic acid, and permanganate with low dosage, and even utilize O2 to decompose pollutants.

This Special Issue aims to cover the reaction mechanisms and the roles of reactive species in novel catalytic processes and materials, with a special focus on the degradation of emergent contaminants and environmental remediation in reused, waste-, surface, and groundwater.

Soil contamination by polycyclic aromatic hydrocarbons (PAHs) has been an environmental issue worldwide, which aggravates the ecological risks faced by animals, plants, and humans. In this work, the composites of nanoscale zero-valent iron supported on carbonylated activated carbon (nZVI-CAC) were prepared and applied to activate persulfate (PS) for the degradation of PAHs in contaminated soil. The prepared nZVI-CAC catalyst was characterized by scanning electron microscopy (SEM), X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS). It was found that the PS/nZVI-CAC system was superior for phenanthrene (PHE) oxidation than other processes using different oxidants (PS/nZVI-CAC > PMS/nZVI-CAC > H2O2/nZVI-CAC) and it was also efficient for the degradation of other six PAHs with different structures and molar weights. Under optimal conditions, the lowest and highest degradation efficiencies for the selected PAHs were 60.8% and 90.7%, respectively. Active SO4−• and HO were found to be generated on the surface of the catalysts, and SO4−• was dominant for PHE oxidation through quenching experiments. The results demonstrated that the heterogeneous process using activated PS with nZVI-CAC was effective for PAH degradation, which could provide a theoretical basis for the remediation of PAH-polluted soil.
