Nanocrystalline titanium oxide powder has been synthesized by reactive plasma processing. The precursor powder of TiH2 was oxidized 'in-flight' in a thermal plasma reactor to effect complete conversion of TiH2 to nano-sized TiO2 powder. Characterization of the powder by various analytical tools indicated that the powder consisted of nano-sized titanium dioxide particles consisting predominantly of the anatase phase. Bactericidal action of illuminated TiO2 on pure culture of Escherichia coli was studied. The plasma synthesized TiO2nano powder catalyst was found to be highly effective for the killing of Escherichia coli. The efficiency of photocatalytic disinfection, used to inactivate Escherischia coli as function of time is discussed.
