Metal-Doped Carbon Dots as Fenton-like Catalysts and Their Applications in Pollutant Degradation and Sensing

Sustainability, Journal Year: 2025, Volume and Issue: 17(8), P. 3642 - 3642

Published: April 17, 2025

Metal-doped carbon dots (CDs) have become one of the most popular catalytic materials for Fenton-like reactions, mainly due to their low production cost, minimal toxicity, and high efficiency. Theses reactions not only provide an efficient decontamination method degradation organic pollutants in wastewater but also demonstrate a wide range sensing applications. Metal doping introduces new catalytically active centres, which increase binding selectivity reactants offer additional advantage improved activity. The metal-doped CDs optimise electronic structure pristine CDs, thereby enhancing properties reaction rates. These enhancements make them attractive option water treatment sensor design. objective this review is comprehensive overview current research progress utilisation as catalysts This examines advantages terms efficiency, selectivity, application scope discusses potential challenges future directions. aim promote further sustainable green development CD technology environmental governance analytical chemistry.

Cost-effective synthesis of stable CoxC@few-layered graphene nanostructures embedded in a carbon matrix

Journal of Alloys and Compounds, Journal Year: 2024, Volume and Issue: 995, P. 174799 - 174799

In this study, a two-step surfactant sol-gel strategy is developed to synthesize Co particles with confined sizes in the nanoscale using organic precursors. This approach does not require use of vacuum techniques or strong reducing atmospheres, making it simple economically attractive. The involves generation few-layered graphene shells provide chemical stability, prevent oxidation and aggregation tendencies. Additionally, study investigates precursors based on nitrates acetates, exploring their structural magnetic properties densified samples. Remarkably, are competitive for both approaches, coercivities reaching up 300 Oe saturation magnetization ∼60 ∼80 emu/g samples acetates prepared at 650 °C, respectively. However, observed that smaller more uniformly sized nanoparticles (around ∼10 nm) obtained nitrate-based due an effective ligand decomposition process. Therefore, offers confinement intriguing through cost-effective reproducible synthesis.
