Photocatalytic water splitting has been considered as one of the most promising methods to produce hydrogen as a source of clean fuel. Use of co-catalysts and elemental doping in TiO 2 has been extensively explored for effective photocatalysis. Here we report the synthesis of visible light responsive and Pt on the N-TiO 2 nanoparticles, showed much higher photocatalytic activity for hydrogen production than that prepared by the one-step method, where Co 3 O 4 is evenly dispersed in N-TiO 2 .The position of the co-catalyst Co 3 O 4 in TiO 2 has a significant effect on the photocatalytic properties of the prepared photocatalysts.
