Abstract: We report a facile method for the synthesis of Na+/Ca2+ ions modified TiO2 xerogels by coprecipitation followed by calcination process. The resultant materials are well characterized by powder X-ray diffraction, Raman spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy and high resolution transmission electron microscopy. Presence of sodium and calcium ions can influence the crystallinity of rutile TiO2. The photocatalytic performances of bare rutile TiO2 along with modified materials such as Na-TiO2, Ca-TiO2, Na-Ca-TiO2 materials are evaluated by calculating the amount of hydrogen evolved during the photocatalytic decomposition of water under light irradiation.This study will be effective informulating the effect of alkali/alkaline earth metal ions on the photocatalytic activity of rutile TiO2.
