Advanced oxidation processes (AOPs), based on sulfate radical (SO) produced by peroxymonosulfate (PMS), can effectively mineralize refractory organic pollutants. However, the coexistence of anions and natural organic matters in actual wastewater prevents the application of AOPs. A simple one-step method was used to prepare FeS/FeO co-modified biochar materials (FFB) that could activate PMS to degrade quinclorac (QNC) with a removal rate of 100%, even exhibiting optimum degradation of QNC reached 99.

Herein, biochar with abundant nitro and carboxyl groups is prepared, which can be assembled into self-supporting electrode. Under the catalyzation of electricity, the surface decorated -NO on the biochar can be in situ transformed into -NH.

- - The text discusses the limitations of current photocatalytic materials for controlling food pathogens, which often rely on metals that lack stability and may cause secondary pollution, prompting interest in non-metallic alternatives.
- - A new non-metallic composite called B@RP, made from rice shell biochar and red phosphorus, was created to effectively eliminate bacteria like E. coli through photocatalysis and photothermal effects.
- - B@RP demonstrated impressive performance by completely removing E. coli within 2 hours of exposure to light, maintaining 100% sterilization efficiency after 9 cycles, making it a promising, safe option for the food industry.
