Fast and complete degradation of Congo red under visible light with Er3+ and Nd3+ ions doped TiO2 nanocomposites

Narayan, Himanshu; Alemu, Hailemichael; Alotsi, Ntjamang Daniel; Macheli, Lebohang; Thakurdesai, Madhavi; Jaybhaye, Sandesh; Singh, Arvind (PAGEPress, 2012)

We report fast and complete destruction of the dye Congo red (CR) under visible light in the presence of Nd3+ and Er3+ doped TiO2 nanocomposites (NCs). TiO2 NCs with general composition TiO2[R2O3]x, {x=0.1, 0.2; R≡ Nd, ...
Role of particle size in visible light photocatalysis of Congo Red using TiO2⋅[ZnFe2O4]x nanocomposites

Narayan, Himanshu; Alemu, Hailemichael; Macheli, Lebohang; Sekota, 'Mantoa; Thakurdesai, Madhavi; Gundu Rao, T. K. (Springer-Verlag, 2009)

TiO2⋅[ZnFe2O4]x (x = 0⋅0–0⋅5) nanocomposites (NCs) with an average particle size of 72⋅4 nm were synthesized by the method of co-precipitation/hydrolysis (CPH). For the comparison of particle-size dependent effects, a ...
Synthesis and characterization of Y3+-doped TiO2 nanocomposites for photocatalytic applications

Macheli, Lebohang; Narayan, Himanshu; Alemu, Hailemichael; Gundu Rao, T. K.; Thakurdesai, Madhavi (IOP Publishing Ltd, 2009)

The TiO2·[Y2O3]x (x = 0.1–0.4) nanocomposites (NCs) with an average particle size of 74 nm were prepared by the method of chemical co-precipitation followed by hydrolysis (CPH). Their visible light photocatalytic activity ...
