Recent advances in oxidative degradation of plastics

Chemical Society Reviews, Journal Year: 2024, Volume and Issue: 53(14), P. 7309 - 7327

Published: Jan. 1, 2024

Oxidative degradation is a powerful method to degrade plastics into oligomers and small oxidized products. While thermal energy has been conventionally employed as an external stimulus, recent advances in photochemistry have enabled photocatalytic oxidative of polymers under mild conditions. This tutorial review presents overview degradation, from its earliest examples emerging strategies. briefly discusses the motivation development with focus on underlying mechanisms. Then, we will examine modern studies primarily relevant catalytic degradation. Lastly, highlight some unique using unconventional approaches for polymer such electrochemistry.

Constructing Stable N-Doped Iron-Based Porous Carbon Nanocatalyst for Antibiotic Degradation and Bactericidal Detoxification

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: March 17, 2025

N-doped iron-based carbon is a promising catalyst to achieve peroxydisulfate (PDS) activation, but constructing efficient and stable catalysts with uniformly distributed firmly anchored nitrogen iron sources remains challenging. Herein, we developed magnetic porous (NMPC) through self-polymerization high-temperature pyrolysis of polydopamine Fe3+ coordination complexes explored it for PDS activation in antibiotic (tetracycline (TC) ciprofloxacin) degradation bactericidal detoxification. The NMPC/PDS system performed both radical nonradical catalytic pathways effective exhibiting 99.8% removal TC. Thanks the strong Fe3+, resulting NMPC could confine species N-carbonaceous matrices efficiently prevent severe leaching, demonstrating good recyclability. It maintain rate as high 92.4% after 5 cycles. After cycling, leaching only 0.026 mg/L, which much lower than WHO guideline value limits drinking water 0.3 mg/L. Moreover, exhibits excellent stability compatibility various conditions, including pH variations (3–9), coexisting substances, different sources. In addition, this an disinfection Escherichia coli Staphylococcus aureus, ratio more 99.9%. Toxic intermediate prediction cell toxicity experiments further prove that TC wastewater significantly reduced treatment system.
