Status and Enhancement Techniques of Plastic Waste Degradation in the Environment: A Review

Sustainability, Journal Year: 2024, Volume and Issue: 16(21), P. 9395 - 9395

Published: Oct. 29, 2024

Plastic waste has been gradually accumulating in the environment due to rapid population growth and increasing consumer demand, posing threats both human health. In this overview, we provide a comprehensive understanding of degradation plastics real environments, such as soil, aquatic environment, landfill, compost. Both conventional biodegradable exhibit limited except for during industrial composting with high thermophilic temperatures. Meanwhile, also review techniques enhanced physical technologies (e.g., photocatalysis, mechanical degradation, pyrolysis), chemical hydrolysis, alcoholysis, ammonia, strong oxidation, supercritical fluids), biotechnologies microorganisms, microfauna, microalgae). The future research directions enhancement plastic are discussed, establishment equivalency standards, adoption internal control techniques, precise recycling products, ecotoxicology their products. Therefore, comprehensively summarizes state environments proposes methods improve providing theoretical basis disposal plastics.

Co single atoms/nanoparticles over carbon nanotubes for synergistic oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid

Chemical Synthesis, Journal Year: 2024, Volume and Issue: 4(4)

Published: Nov. 5, 2024

The preparation of high-value 2,5-furandicarboxylic acid (FDCA) from biomass-based platform compound 5-hydroxymethylfurfural (HMF) is an important synthetic reaction, as the resulting FDCA holds promise to replace terephthalic produce environmentally friendly polyester materials. However, due complex tandem nature oxidation HMF FDCA, which involves several stable intermediates, efficient conversion and achieving a high yield remain challenging. Herein, catalyst Co SAs/NPs@N-CNTs comprising single atoms (Co SAs) alongside nanoparticles NPs) supported on carbon nanotubes (CNTs) was synthesized. exhibited outstanding catalytic activity for selective 100% 94.2% yield. This remarkable performance attributed synergistic effect between SAs NPs. Poisoning treatment experiments indicated that served active sites, while NPs did not directly act sites. Instead, merely assisted sidelines, facilitating into various intermediates promoting further these thereby productivity. strategy offers new insights designing catalysts reactions.
