Green Synthesis of Nanocomposite Catalysts for Environmental Remediation

Abstract

This research explores the effectiveness of environmentally friendly nanocomposite catalysts for cleaning up polluted areas. The results of the characterization showed that nanocomposite A had particles that were 20 nm in size, a surface area of 50 m^2/g, and a pore volume of 0.1 cm^3/g. In contrast, nanocomposite E had particles that were 15 nm in size, a surface area of 45 m^2/g, and a greater pore volume of 0.08 cm^3/g. Evaluations of the effectiveness of the catalysts in removing pollutants showed that nanocomposite E was the most effective, with removal percentages of 95% for Pollutant A, 90% for Pollutant B, and 98% for Pollutant C. Analyses of the reaction kinetics showed that nanocomposite E had the best catalytic kinetics, with a rate constant of 0.08 min^-1 and a turnover frequency of 0.003 mol/g/min. As compared to other catalysts, nanocomposite C had the lowest cost per gram and the highest cost efficiency, making it the most cost-effective alternative. With nanocomposite E showing better efficiency in pollutant removal and catalytic kinetics, the results indicate that catalysts made of nanocomposite materials using green techniques might be used for long-term, effective environmental cleanup. Based on these findings, nanocomposite catalysts have great promise for promoting environmental sustainability and protection.
