Singlet oxygen (1 O2 ) plays a significant role in environmental and biomedical disinfection fields. Electrocatalytic processes hold great potential for 1 generation, but remain challenging. Herein, facile Ni doping converted spin-state transition approach is reported boosting production. Magnetic analysis theoretical calculations reveal that occupied at the octahedral site of Co3 O4 can effectively induce low-to-high transition. The high-spin Ni-Co3 generate appropriate binding strength enhance electron transfer between Co centers with intermediates, thereby improving catalytic activity effective generating . In neutral conditions, 1×106 CFU mL-1 Gram-negative ESBL-producing Escherichia coli (E. coli) could be inactivated by system within 5 min. Further antibacterial mechanisms indicate lead to cell membrane damage DNA degradation so as irreversible death. Additionally, developed inactivate bacteria from wastewater bioaerosols. This work provides an strategy designing electrocatalysis boost generation process.

Abstract The electrocatalytic oxidation of 5‐hydroxymethylfurfural (HMF) provides a feasible way for utilization biomass resources. However, how to regulate the selective synthesis multiple value‐added products is still great challenge. cobalt‐based compound promising catalyst due its direct and indirect properties, but weak adsorption capacity restricts further development. Herein, by constructing Ag─Co(OH) 2 heterogeneous catalyst, efficient 5‐hydroxymethyl‐2‐furanoic acid (HMFCA) 2,5‐furan dicarboxylic (FDCA) at different potential ranges are realized. Based on various physical characterizations, electrochemical measurements, density functional theory calculations, it proved that addition Ag can effectively promote aldehyde group carboxyl group, then generate HMFCA low potential. Moreover, introduction activate compounds, thus strengthening organic molecules OH − species, promoting formation FDCA. This work achieves two chemicals one tandem deeply analyzes enhancement mechanism which powerful guidance development catalysts.
