Tio2 powder photocatalyst from sol-gel route and its immobilisation with cement for photocatalytic phenol removal

Two types of TiO2 powders of water-to-TPT ratios (Powder 1: water/TPT = 1 and Powder 2: water/TPT= 2) were synthesized via sol-gel method. The effect of hydrolysis degree on the formation of TiO2 powder particles was investigated using various physical-chemical characterization methods. The synthesi...
