High temperature stability of nanocrystalline anatase powders prepared by chemical vapour synthesis under varying process parameters

► Nanocrystalline titania synthesised by chemical vapour synthesis process under varying gas flow rates. ► With increasing O2/He flow rate ratio the chemical by product shifted from C3H6 to CO2, which resulted in carbon getting into the structure of Anatase. ► Carbon incorporation into anatase enhanced its stability to higher temperatures.
