Notes:
Ti0.6Cr0.4OxNy bimetallic metal oxynitride nano powder was synthesized by ammonolysis ofthe nanosized Cr2O3/TiO2 composite powder with n(Ti):n(Cr)=6:4 at 800oC for 8 h. The precursor and theresulting oxynitride were characterized by Auger electron spectroscope (AES), X-ray diffraction analysis(XRD), electron probe microanalysis (EPMA), transmission electron microscopy (TEM), and BETsurface area techniques. The result indicated that the precursor was homogenous mixture of Cr2O3 andTiO2 with high BET surface area. The as-synthesized oxynitride powder contains only Ti0.6Cr0.4OxNy withcubic structure. The BET surface area of the oxynitride powder is 37.42 m2/g and the particle size is in therange of 20~30 nm
