Single Atom Catalyst in Persulfate Oxidation Reaction: From Atom Species to Substance

Small, Journal Year: 2024, Volume and Issue: 20(30)

Published: March 5, 2024

Abstract With maximum utilization of active metal sites, more and researchers have reported using single atom catalysts (SACs) to activate persulfate (PS) for organic pollutants removal. In SACs, atoms (Fe, Co, Cu, Mn, etc.) different substrates (porous carbon, biochar, graphene oxide, carbon nitride, MOF, MoS 2 , others) are the basic structural. Metal atoms, substances, connected chemical bonds all a great influence on electronic structures that directly affect activation process PS degradation efficiency pollutants. However, there few relevant reviews about interaction between substances during process. this review, SACs with species summarized investigate metal−support evaluate their effects oxidation reaction Furthermore, how reactive pathways also discussed. Finally, challenges prospects in PS‐AOPs proposed.

Mineral-mediated stability of organic carbon in soil and relevant interaction mechanisms

Eco-Environment & Health, Journal Year: 2024, Volume and Issue: 3(1), P. 59 - 76

Published: Jan. 3, 2024

Soil, the largest terrestrial carbon reservoir, is central to climate change and relevant feedback environmental health. Minerals are essential components that contribute over 60% of soil storage. However, how interactions between minerals organic shape transformation stability remains poorly understood. Herein, we critically review primary mechanisms, including sorption, redox reaction, co-precipitation, dissolution, polymerization, catalytic reaction. These interactions, highly complex with combination multiple processes, greatly affect through following processes: (1) formation or deconstruction mineral-organic association; (2) oxidative minerals; (3) polymerization (4) varying association according mineral transformation. Several pieces evidence related turnover during interaction in real eco-environment then demonstrated. We also highlight current research gaps outline priorities, which may map future directions for a deeper mechanisms-based understanding storage capacity considering its minerals.

Copper, Iron, Cadmium, and Arsenic, All Generated in the Universe: Elucidating Their Environmental Impact Risk on Human Health Including Clinical Liver Injury

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(12), P. 6662 - 6662

Published: June 17, 2024

Humans are continuously exposed to various heavy metals including copper, iron, cadmium, and arsenic, which were specifically selected for the current analysis because they among most frequently encountered environmental mankind industrial pollutants potentially causing human health hazards liver injury. So far, these issues poorly assessed remained a matter of debate, also due inconsistent results. The aim actual report is thoroughly analyze positive as well negative effects four on health. Copper iron correctly viewed pollutant elements essential maintaining part important enzymes metabolic pathways. Healthy individuals prepared through genetically based mechanisms maintain cellular copper homeostasis, thereby circumventing or reducing hazardous organ injury excessive amounts entering body.

Recent Advances in Coke Management for Dry Reforming of Methane over Ni-Based Catalysts

Catalysts, Journal Year: 2024, Volume and Issue: 14(3), P. 176 - 176

Published: March 1, 2024

The dry reforming of methane (DRM) is a promising method for controlling greenhouse gas emissions by converting CO2 and CH4 into syngas, mixture CO H2. Ni-based catalysts have been intensively investigated their use in the DRM. However, they are limited formation carbonaceous materials on surfaces. In this review, we explore carbon-induced catalyst deactivation mechanisms summarize recent research progress mitigating carbon deposition developing coke-resistant catalysts. This review emphasizes significance support, alloy, structural strategies, importance comprehending interactions between components to achieve improved catalytic performance stability.
