Biochar/metal nanoparticles-based composites for Dye remediation: A review

Hybrid Advances, Journal Year: 2024, Volume and Issue: 6, P. 100254 - 100254

Published: July 24, 2024

Dyes pose a significant environmental hazard due to their widespread use and tenacity in water bodies, resulting adverse ecological health effects. Many strategies have been investigated for the removal of dyes, adsorption has emerged as viable technique. Biochar-based adsorbents provide sustainable alternative because high capacity, variable surface characteristics, availability. Biochar improved properties similar specific area, porosity, total pore volume when mixed with metal nanoparticles synergistic interactions. It is crucial comprehend isotherm kinetic models that control dye onto biochar they insight into mechanism equilibrium behavior, respectively. The process's viability energetics are further clarified by thermodynamic studies. Experiments parameter optimization guided computational studies methods such density functional theory (DFT) response methodology (RSM) optimize processes giving system's relationship between multiple independent variables electron structure. This review also highlights cost-effectiveness sustainability biochar/metal nanoparticle composites discussing techniques regeneration reuse explains composites.

Novel magnetite/persulphate/ozone hybrid system for catalytic degradation/ozonation of sunset yellow dye from wastewater

Nanocomposites, Journal Year: 2024, Volume and Issue: 10(1), P. 122 - 138

Published: April 4, 2024

Food dyes with a diverse set of colorants stimulate appetite and enhance aesthetic charm food on table but at the same time these contaminate aquatic biological ecosystems due to their cytotoxic carcinogenic potentials. Herein, we report magnetite catalyzed removal sunset yellow dye from water through catalytic degradation ozonation. The catalyst revealed about 83% 92% ozonation performance toward 100 25 min, respectively. Furthermore, persulphate/magnetite/O3 hybrid system superior compared persulphate/magnetite under identical conditions. Kinetic studies that data followed second-order kinetics, suggesting process is physicochemical in nature. This study further demonstrates persulfate/magnetite/O3 can efficiently decompose aqueous solution Fenton's reagent simple decomposition processes which attributed its unique structural features.

Photodegradation of Aqueous Tetracycline Using CuS@TiO₂ Composite under Solar-Simulated Light: Complete Mineralization, Catalyst Efficiency, and Reusability

Heliyon, Journal Year: 2025, Volume and Issue: 11(2), P. e41662 - e41662

Published: Jan. 1, 2025

While CuS/TiO₂ has been previously synthesized and employed in a limited number of photodegradation studies, the current study investigated its effectiveness for TC degradation under UV-visible light irradiation. CuS is known to be nontoxic, environmentally friendly material; hence, it great potential as an alternative CdS CdSe, which are used conventionally sensitizers. In this work, photocatalysts achieved maximum 95 % removal at initial concentration 20 ppm, confirming good utilization active sites. Even though efficiency decreased higher concentrations due saturation sites, values quantum yield showed that photon was still effective. Consequently, photocatalyst optimum 0.20 g, further addition increased rather insignificantly. near-complete mineralization by composite with few byproducts, reusability excellent because almost consistent performance successive cycles. These results confirm continuous relevance practical, sustainable solution organic pollutant degradation, reinforcing value environmental remediation applications.
