摘 要：<正> ZrO2-SnO2 composite nanoparticles were prepared by heating the hydrate precursors synthesized by the chemicalco-precipitation reaction of ZrOCl2 and SnCl4. The precursors were examined by differential thermal analysis （DTA） andthermogravimetric analysis （TGA）. The composite powder was characterized using X-ray diffraction （XRD）, transmissionelectron microscopy （TEM） and desorption isotherm （Barrett-Joyner-Halenda method）. The average crystal size of thenanoparticle ranges from 15 to 30 nm for the sample containing 5%-25% ZrO2 （mass fraction）. Most of the pores in theZrO2-SnO2 nanoparticles are about 10-20 nm in diameter. The composite powder is promising for chemical sensors.
