A novel synthetic route was developed to prepare nano-sized and well-dispersed phosphides of transition metals (Mo, Ni, Co) from their corresponding oxide precursors. The current approach produced metal in dimethyl ether (DME) using the rapid heating reduction (RHR) method. synthesis DME interesting, since composition gas-phase products predominantly H2, CO CH4 with a minor amount CO2 but without H2O. Based on XRD MS results, formation mechanism proposed. overall process cannot simply be regarded as an precursor decomposition DME. product distribution should ascribed combination other catalytic reactions. In addition, it is noteworthy that compared traditional method, viz. temperature-programmed H2 (TPR-H2), present method used higher rate shorten reaction time can yield more finely dispersed phosphide nanoparticles. good dispersion nanoparticles probably achieved due fact no H2O released RHR-DME process, which avoid strong hydrothermal sintering.
