23/6/2000· TiO2 in anatase crystal phase is a very effective alyst in the photoalytic oxidation of organic compounds in water. To improve the recovery rate of TiO2 photoalysts, which in most cases are in fine powder form, the chemical vapor deposition (CVD) method was used to load TiO2 onto a bigger particle support, silica gel. The amount of titania coating was found to depend strongly on the
