Synthesis of Tio2-Sio2 powder photocatalyst via sol-gel method: Effect of titanium precursor type on powder properties
Radhiyah, Abd Aziz; Nor Asyikin; Iis, Sopyan, Dr. (The Institution of Engineers, Malaysia, 2009-12)TiO2-SiO2 powder photocatalysts with varied SiO2 portion were prepared through sol-gel technique using two types of metal alkoxides: titanium tetraisopropoxide (TPT) and titanium diisopropoxide (PTP). Tetraethoxysilane ... -
TiO2 powder photocatalyst from sol-gel route and its immobilisation with cement for photocatalytic phenol removal
Nor Hafizah; Parveen, Jamal; Mohamed Ismail, Abdul Karim, Prof. Dr.; Iis, Sopyan (The Institution of Engineers, Malaysia, 2009-12)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 ...
