Carbon nanotubes (CNTs)/SnO2 composites were prepared by a simple liquid phase deposition method. The composite electrodes were prepared for electrocatalytic degradation of organic wastewater. Electrocatalytic performance of the CNTs/SnO2 composite electrodes improves remarkably as compared with that of activated carbon composite and graphite composite electrodes, due to the high surface area and excellent conductivity of CNTs as well as the excellent electrocatalytic performance of SnO2. The electrocatalytic capacity of the electrodes of CNTs/SnO2 composites, which were prepared with functional CNTs and 40% SnO2 as well as calcined at 600 ℃, is the double of that of pristine CNTs electrodes.

Key words: carbon nanotube, tin oxide, electrocatalytic oxidation, organic wastewater
