AN IMPROVED SOL-GEL PROCESS FOR THE PREPARATION OF NANOCRYSTALLINE CeTi2O6 POWDER

摘要

The present invention provides an improved sol-gel process for the preparation of nanocrystalline CeTi2O6 compound, which has applications in the area of photocatalytic activity. This compound can be obtained by completely drying the solution, which comprises both titanium and cerium precursors into a xerogel and sintering it at a temperature of 1400 °C for 5 min. in air. The Ce:Ti mole ratio in the precursor sol for the preparation of this compound is identified in the range of 0.33:1 and 0.6:1.
