Abstract

An easy and size controlled solvothermal synthesis of CeO 2 hollow spheres is still a challenge in the area of materials synthesis. Here, CeO 2 hollow spheres have been synthesized using PVA500# as a surfactant via solvothermal reaction followed by calcinations. The size of CeO 2 hollow spheres could be controlled from 500 to 150 nm by changing the amounts of Ce(NO 3) 3·6H 2O and PVA500#. The possible growth mechanism of CeO 2 hollow sphere was explained. The CO oxidation catalytic activity of the CeO 2 hollow spheres were superior to that of the commercial CeO 2 powder due to the high specific surface area and small crystallite size.
