| Abstract: | Using palladium chloride (PdCl2) as the palladium precursor, ethanol as reducing agent and poly (vinyl pyrrolidone) (PVP) as a stabilizer and guiding agent, palladium (Pd) multiply twinned particles (MTPs) were synthesized via photothermally assisted solution approach with visible light from a commercial energy-saving lamp as light source. The morphologies, crystal structure, optical properties and the stability of Pd MTPs were characterized by high resolution transmission electron microscopy (HRTEM), fast Fourier transformation (FFT), powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), UV-Visible spectroscopy and Fourier transform infrared (FT-IR) spectroscopy, respectively. The electrocatalytic properties of the Pd MTPs modified glassy carbon electrode for ethanol oxidation were investigated by cyclic voltammetry. The results showed that the formation of Pd MTPs depends on the coordination interaction of light and thermal effects. Surface plasmon resonance (SPR) peak of Pd MTPs is located at the visible region. This material exhibits remarkable electrocatalytic activity and anti-poisoning faculty for the ethanol oxidation. |
