Iron Single-Atom Based Double-Reaction-Center Catalysis Triggers Internal-Driven and External-Driven Pathways for Green Fenton-Like Chemistry.

Double-reaction-centers (DRCs) Fenton-like chemistry with low or zero oxidant addition has garnered increasing attentions due to their alignment with the principles of green and sustainable development. However, the regulation of such processes remains a significant challenge, primarily due to deficiencies in the microscopic interpretation of their electron migration mechanisms operating with low or zero oxidant addition. In this work, iron single-atom DRCs catalyst (Fe/N-SAC) was prepared for internal-driven system (zero oxidant addition) and external-driven system (low peroxymonosulfate [PMS] addition).

Co-catalysis strategy for low-oxidant-consumption Fenton-like chemistry: From theoretical understandings to practical applications and future guiding strategies.

Recently, great effects have been made for the co-catalysis strategy to solve the bottlenecks of Fenton system. A series of co-catalysis strategies using various inorganic metal co-catalysts and organic co-catalysts have been developed in various oxidant (i.e.

Enhanced chlortetracycline removal by iron oxide modified spent coffee grounds biochar and persulfate system.

Chlortetracycline (CTC) is a tetracycline derivative antibiotic that has been widely used in the livestock industry for prophylactic and therapeutic purposes. Effective measures should be taken to decrease the environmental risks associated with CTC-rich waste. Biochar produced by biomass waste showed great potential for organic contaminants removal by adsorption and catalytic degradation.
