摘要
In this paper, the molybdenum phosphide(MoP) catalysts(TPR-MoP and TPR-MoP-Pla) were prepared by the traditional method and the RF(radio frequency) thermal plasma technique respectively and characterized by x-ray diffraction(XRD), x-ray photoelectron spectroscopy(XPS), transmission electron microscope(TEM), hydrogen temperature-programmed desorption(H_2-TPD) and carbon monoxide temperature-programmed desorption(CO-TPD) measurements,and their catalytic performance for HAS was evaluated. The results showed that the total and C_(2+) alcohols selectivity of the catalyst after plasma treatment(TPR-MoP-Pla) were enhanced.The enhanced catalytic performance could be related to more dislocation defects and the synergistic effect between Mo^(0–2+) and Mo^(4+) valence species in the TPR-MoP-Pla catalyst. In addition, this work suggests that thermal plasma treatment can be used as a new preparation technique for the synthesis of materials with rich species.
