摘 要：<正>Nanometer RuO2-SnO2was synthesized by the citrate-gel method using RuCl3,SnCl4 as cation sources,citric acid as complexing agent and anhydrous ethanol as solvent.The structures of the derived powders were characterized by thermogravimetric and differential thermal analysis,X-ray diffraction,transmission electron microscope,and Brunauer-Emmett-Teller surface area measurement.The pure,fine and amorphous powders was obtained at 160℃.The materials calcined at above 400℃were composed of futile-type oxide phases having particle sizes of fairly narrow distribution and good thermal resistant properties.By adding SnO2 to RuO2,the Ru metallic phase can be effectively controlled under a traditional temperature of preparation for dimensional stable anode.
