The effect of hydrolysis degree on the formation of TiO2 powder particles was investigated using various physical-chemical characterization methods. The synthesized powders were then immobilised by mixing them with cement to be cement-bonded TiO2 photocatalyst. For photocatalytic measurement, phenol solution was selected as a model of pollutant to be degraded by both cement-bonded TiO2 photocatalysts to analyse their photocatalytic efficiency. The photodegradation of phenol test revealed cement-bonded TiO2 Powder 2 was more efficient than Powder 1 due to its high crystallinity which can lead to faster charge separation and the increased number of phenol molecules adsorbed. 2011-09-07T19:07:47Z 2011-09-07T19:07:47Z 2009-12 Article The Journal of the Institution of Engineers, Malaysia, vol. 70(4), 2009, pages 49-56 0126-513X http://www.myiem.org.my/content/iem_journal_2009-180.aspx http://hdl.handle.net/123456789/13678 en The Institution of Engineers, Malaysia
