Fabrication of a novel Ti3C2-modified Sb-SnO2 porous electrode for electrochemical oxidation of organic pollutants

•Ti3C2 served as a pore-forming agent for preparing porous Sb-SnO2 electrode.•Ti3C2-contained electrolyte could regulate the Sb-Sn alloy nucleation process to decrease its domain size.•High-conductive Ti3C2 improves the metal ions diffusion process to increase the Sb-SnO2 loading amount.•Ti3C2-modified Sb-SnO2 electrode achieved good degradation performance for methylene blue, methylene orange, norfloxacin, and P-phenylenediamine.
