“…As shown in Table 1 and Fig. 4 c, 80-Fe 3 O 4 /S-WO 3 could completely decompose PMS molecular in 5 min, while other Fenton-like catalysts can’t efficiently activate PMS, such as PC-MnO x (55% in 30 min) [35] , Fe 3+ /MgAl-MoS 4 system (81% in 60 min) [33] and CuCo@ZnO (74.7% in 80 min) [34] . Apart from PMS decomposition efficiency, the PMS utilization efficiency is also an important parameter.…”

“…Compared with Fe 3 O 4 (0.029) and S-WO 3 (0.017) alone, the composite 80-Fe 3 O 4 /S-WO 3 exhibited the highest PMS utilization efficiency (0.128). Furthermore, the 80-Fe 3 O 4 /S-WO 3 still showed outstanding PMS utilization efficiency as compared to PC-MnO x (0.049) [35] , Fe 3+ /MgAl-MoS 4 system (0.048) [33] , CuCo@ZnO (0.2) [34] , Fe 3 O 4 @MoS 2 -3 (0.116) [6] and other reported excellent catalysts. Thanks to the interaction between Fe 3 O 4 and S-WO 3 , the catalytic ability of the composite was dramatically enhanced.…”

Sulfate radicals (SO4−) play important biological roles in biomedical and environmental engineering, such as antimicrobial, antitumor, and disinfection. Compared with other common free radicals, it has the advantages of a longer half-life and higher oxidation potential, which could bring unexpected effects. These properties have prompted researchers to make great contributions to biology and environmental engineering by exploiting their properties. Peroxymonosulfate (PMS) and peroxydisulfate (PDS) are the main raw materials for SO4− formation. Due to the remarkable progress in nanotechnology, a large number of nanomaterials have been explored that can efficiently activate PMS/PDS, which have been used to generate SO4−·for biological applications. Based on the superior properties and application potential of SO4−, it is of great significance to review its chemical mechanism, biological effect, and application field. Therefore, in this review, we summarize the latest design of nanomaterials that can effectually activate PMS/PDS to create SO4−, including metal-based nanomaterials, metal-free nanomaterials, and nanocomposites. Furthermore, we discuss the underlying mechanism of the activation of PMS/PDS using these nanomaterials and the application of SO4− in the fields of environmental remediation and biomedicine, liberating the application potential of SO4−. Finally, this review provides the existing problems and prospects of nanomaterials being used to generate SO4−· in the future, providing new ideas and possibilities for the development of biomedicine and environmental remediation.

Selective activation of peroxymonosulfate (PMS) represents an efficient route to generate the reactive oxygen species (ROS) for the degradation and deep mineralization of organic pollutants, but its activity and selectivity are remarkably lower than what is needed. Herein, an S‐scheme heterojunction is developed to effectively modify surface electronic properties and introduce abundant oxygen vacancies, thereby enabling photo‐enhanced PMS activation for selective removal of gaseous toluene. S‐scheme heterojunction is fabricated by in situ growth of ultrathin Co3O4 nanoparticles on g‐C3N4 nanosheets through a rapid plasma treatment. The electronic field at the S‐scheme heterostructure interface of Co3O4/g‐C3N4 (COCN) facilitates charge transfer, selectively removing low‐redox electrons and holes while separating high‐redox ones. Photo‐excited electrons promote the Co3+/Co2+ redox cycle, thereby enhancing ROS generation and creating continuous PMS activation sites. The COCN catalyst demonstrates remarkably high degradation efficiency (90.2%) and mineralization rate (68.5%) for flowing gaseous toluene in aqueous solution. This study thus provides a feasible strategy for plasma‐induced electronic modulation and offers new insights for future heterojunction design aimed at efficient PMS activation.
