Modification of semiconductor oxides leads to a major development in functional characteristics. Characterisation of Pr6O11-TiO2, fabricated by a cost-effective hydrothermal - decomposition method reveals the nanorod like structure of this catalyst. The XRD pattern definite the formation of face-centred cubic or cubic close-packed structure of Pr(6)O(11)and the high crystallinity indicate the existence of anatase TiO2. XPS analysis indicates the presence of both Pr(3+)and Pr(4+)ions in Pr6O11.Pr6O11-TiO(2)is more photoactive under visible light than Pr6O11, prepared TiO(2)and TiO2-P25 (80% Anatase and 20% Rutile mixture) in the degradation of toxic azo dyes. Pr6O11-TiO(2)is stable and recyclable consecutively. Pr6O11-TiO(2)catalyst shows higher electrocatalytic activity in methanol oxidation than pure TiO2. These results reveal new insights on the efficiency of catalysts in photo- and electrocatalytic applications.
