Summary:The motivation of this work is to develop an efficient and relatively inexpensive material architecture using titanium oxide nanotubes for hydrogen generation. Hydrogen is an environment friendly energy carrier used in the field of transport, power generation, and in various domestic applications. Nano scale materials have many peculiar properties than the bulk ones and have led to break troughs in various fields of science and technology. Titanium oxide nanotubes have attracted much interest in research because of its functional properties such as large surface area. The titanium oxide nanotubes structures are grown and fabricated by electrochemical anodization method at constant DC voltage at different anodization time. Titanium oxide nanotubes formed is characterized by FEG-SEM and the dimensions are analysed. For the first 15 mins of anodization the Nano pores are formed and by increasing the anodization time the size of pores gradually increases. Then finally the titanium oxide nanotubes of 500 nm diameter and length of 50 nm are obtained.
