Abstract
A facile visible-light-assisted method has been demonstrated to synthesize palladium (Pd) nanoparticles (NPs) with single-crystalline multiple-twinned structures by reduction of PdCl2. The structures and electrochemical properties of Pd NPs were investigated by high resolution transmission electron microscopy (HRTEM), UV-visible spectroscopy, and cyclic voltammetry (CV). The results show that the formation of different nanostructures depends on the control of reduction rate. Unlike multiple-twinned Pd NPs, single-crystalline Pd NPs exhibit surface plasmon resonance (SPR) peaks in the visible region. By comparison of the electrochemical parameters in the oxidation process of Pd NPs with single-crystalline and multiple-twinned structures, multiple-twinned Pd NPs exhibit the better electrocatalytic activity and anti-poisoning capability for ethanol oxidation.
