Nano-sized TiO₂ photo catalytic water-splitting technology has great potential for low-cost, environmentally friendly solar-hydrogen production to support the future hydrogen economy. Presently, the solar-to-hydrogen energy conversion efficiency is too low for the technology to be economically sound. The main barriers are the rapid recombination of photo-generated electron/hole pairs as well as backward reaction and the poor activation of TiO₂ by visible light. In response to these deficiencies, many investigators have been conducting research with focused on the enhancement of photo catalysis by modification of TiO₂. This paper focus on the development of TiO₂ film for water splitting system using nano particle deposition system(NPDS).

Fabrication of Micro/Nanostructures is come into the spotlight because of its potential at healthcare, electronic device and military related applications. However, existing fabrication processes contains limits in terms of rapid prototyping, due to its complicate manufacturing process, difficulties in achieving complex structure and limit of available materials. Herein, we developed novel nanoscale 3D printing system by integrating nanoparticle deposition system and focused ion beam.
