doi:10.7503/cjcu20190283

Abstract

Abstract:

Zn(MAA)₂ was introduced to accelerate the reduction of Pd ²⁺ into Pd in PdCl₂ solution. The final sample Pd/PdO nanocomposite microspheres were prepared through calcination. Furthermore, the Pd/PdO nanocomposite microspheres were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), X-ray powder diffraction analysis(XRD) and X-ray photoelectron spectroscopy(XPS). Moreover, UV-visible adsorption spectra were recorded to investigate the performance of Pd/PdO nanocatalysts for the reduction reaction of 4-NTP.

Key words: Pd, PdO, Nanocomposite microspheres, Catalytic performance
