Bm. Reddy et al., PREPARATION OF MIXED-OXIDE SUPPORTS BY HOMOGENEOUS PRECIPITATION METHOD, INDIAN JOURNAL OF CHEMICAL TECHNOLOGY, 1(1), 1994, pp. 60-62
Preparation of catalytically important TiO2-Al2O3, TiO2-SiO2, TiO2-ZrO
2, TiO2-SiO2-ZrO2 and SiO2-ZrO2 mixed oxides by coprecipitation method
using urea as hydrolysing agent is described. These mixed oxides are
X-ray amorphous and exhibit high N(2)BET surface areas.
