Abstract Nano-Pd catalyst have been synthesized by slow reduction of Pd2+ in a quaternary system of brine-cyclohexane-surfactant-cosurfactant with a hexagonal lyotropic liquid crystal as template in a dark place under soft condition. Then the synthesized Pd nano-particles were characterized by optical microscopy、XRD、TEM、and HRTEM with selected area electron diffraction (SAED). The electrocatalytic properties of the nano-Pd modified glassy carbon electrode (Pd/GCE) for ethanol oxidation had been also investigated by cyclic voltammetry. The results show that the synthesized nano-Pd particles after reaction for 24 h show more or less the same shape with regular morphology with a mean size of (31±1) nm. This material exhibits the excellent electrocatalytic activity and anti-poisoning ability for the ethanol oxidation.
