Efficient generation of singlet oxygen (1O2) by hollow amorphous Co/C composites for selective degradation of oxytetracycline via Fenton-like process

Peidong Hong et al.

Summary: This study introduces a novel hollow amorphous Co/C composite for efficient generation of 1O2 to degrade oxytetracycline. The optimized samples showed nearly 100% degradation of oxytetracycline under neutral conditions with good reusability and stability, demonstrating high anti-interference capacity in different water qualities. XPS spectra revealed vital electron cycles contributing to the formation of 1O2, while quenching experiments and EPR testing confirmed 1O2 as the dominant oxidative species in the reaction without hydroxyl radicals. Additionally, Fukui function and T.E.S.T analysis provided valuable insights into degradation pathways and ecological risks of oxytetracycline and its intermediates.

Pyrite-activated persulfate for simultaneous 2,4-DCP oxidation and Cr(VI) reduction

Peng He et al.

Summary: Organic pollutants and heavy metals in wastewater were effectively removed simultaneously using pyrite and persulfate system, where SO4 center dot- and (OH)-O-center dot radicals were identified as the oxidative species responsible for degrading 2,4-DCP. Pyrite acted as a catalyst for Cr(VI) reduction, with Fe identified as the main catalytic site, showcasing a new strategy for the simultaneous removal of heavy metals and organic compounds in wastewater treatment.

Catalytic properties of transition metals modified nanoscale zero-valent iron for simultaneous removal of 4-chlorophenol and Cr(VI): Efficacy, descriptor and reductive mechanisms

Jituo Xie et al.

Summary: The study found that transition-metal modified nanoscale zero-valent iron can effectively remove chlorophenols and Cr(VI) pollutants simultaneously, with the Pd/Fe bimetallic system performing the best. The enhanced catalytic activity of transition metal modified nZVI was attributed to the formation of nano-galvanic cells and atomic hydrogen species, which facilitated electron transfer and played a key role in triggering C-Cl bond cleavage.
