【Abstract】 Multielemental bimetallic molybdenum-tungsten oxide nanorods were synt hesized under mild hydrothermal conditions with the aid of Na2SO4 salt, using fr eshly prepared molybdic-tungstenic acid precipitate as precursor. The products w ere characterized by TEM, SEM, XRD, EDS and PL. The results show that the stoich iometric relation of as-synthesized molybdenum-tungsten oxide nanorods is Mo1.8W 16.2O49. The formation of molybdenum-tungsten oxide nanorod is related to SO42-.更多还原
