Researchers developed single- and bimetallic carbon xerogels by adding iron and iron-cobalt precursors, testing them in catalytic wet peroxide oxidation (CWPO) to degrade ibuprofen in a simulated environment.
The bimetallic catalyst showed significantly better performance—25% higher than the single metal and 85% higher than non-metallic catalysts—after 360 minutes of reaction at a mild temperature of 30°C.
Further optimization for treating hospital wastewater indicated the bimetallic carbon xerogel could achieve up to 80% chemical oxygen demand (COD) removal and 55% total organic carbon (TOC) mineralization in continuous operation, suggesting its potential for efficient wastewater treatment beyond traditional batch methods
