ChemCatChem, Volume 17, Issue 16, August 18, 2025.This study presents a sustainable approach for synthesizing carbon nanotubes (CNTs) via chemical vapor deposition (CVD) using polyolefins as model plastic waste as the carbon source and Ni─Co ferrite catalysts. The CNTs were applied in catalytic wet peroxide oxidation (CWPO) to degrade bisphenol A (BPA) and sulfamethoxazole (SMX), achieving efficient ...
