Effect of tantalum addition on anatase phase stability and photoactivity of aqueous sol-gel derived mesoporous titania

Baiju, K V; Shajesh, P; Wunderlich, W; Mukundan, P; Kumar, S R; Warrier, K G K (Elsevier, 2007)

The effect of the addition of tantalum to nanocrystalline titania matrix on the photocatalytic activity is presented. The tantalum addition increases the anatase phase stability to above 1000 degrees C by inhibiting the ...
Enhanced photoactivity and anatase thermal stability of silica-alumina mixed oxide additives on sot-gel nanocrystalline titania

Baiju, K V; Periyat, P; Krishna Pillai, P; Mukundan, P; Warrier, K G K; Wunderlich, W (Elsevier, 2007)

Nanocrystalline titania with silica and silica-alumina mixed oxide as additives has been prepared through a sequential approach sot-gel method starting from titanyl sulphate in aqueous medium. The mixed oxide added titania ...
Enhanced photoactivity of neodymium doped mesoporous titania synthesized through aqueous sol-gel method

Baiju, K V; Periyat, P; Wunderlich, W; Krishna Pillai, P; Mukundan, P; Warrier, K G K (Springer, 2007)

Nanosize neodymium doped titania has been prepared by hydrolysis of titanium oxychloride followed by peptisation under acidic condition. The anatase to rutile phase transformation temperature was found to increase by 150 ...
