Niobium oxide dispersed over PET waste activated carbon: an efficient catalyst for oxidation of the fungicide prothioconazole
Composite materials based on Nb 2 O 5 nanoparticles dispersed over activated carbon (Nb/AC) obtained from PET waste were used as catalysts for wastewater treatment. These composites were synthesized by mechanical mixing of AC and commercial Nb 2 O 5 , followed by H 2 O 2 treatment. The methylene blu...
