Open publisher page 0 citations

Abstract

Phosphoric acid solution was used as the raw material to make TiO2.The effects of adhesive proportion,calcination time,calcination temperature in the preparation process were investigated.The characteristics of the carrier were determined by using X-ray diffraction(XRD),surface detection system(BET) and scanning electron microscopy(SEM).The results showed that the carrier of the catalyst was in the form of anatase under the following conditions:drying temperature at 105 ℃,calcination temperature at 800 ℃,calcination time of 4 h.
