Sustainable Photocatalytic Materials for Environmental Remediation

Strategic Insights -

A new study published in Environmental Research reveals the development of photocatalytic materials utilizing biomass-based materials for efficient degradation of organic pollutants. Researchers from Autonomous University San Luis Potosi explored the potential of agave bagasse, a waste product from tequila production in Mexico, as a sustainable catalytic support doped with cerium oxide nanoparticles (CeONP) to degrade methylene blue (MB). The study demonstrated that the hybrid structure achieved over 99.5% degradation of MB under UV light, making it a promising solution for waste management and environmental applications.
