Abstract The demand of energy in Indonesia is still dominated by the use of fossil fuels. In 2013, fossil fuels contributed 94.3 percent of the total energy. However, production of fossil fuels: coal, oil, and gas has been decreasing very significantly. Additionally, high energy requirements has not been matched with an equitable electrification ratio throughout Indonesia. To overcome the above energy problems, hence hydrogen (H2) can be used as an alternative and potential energy supplier because it is an environmentally friendly energy source. An effort to produce H2 is by utilizing water. Water can be converted into H2 through photocatalyst process applying photon energy and using TiO2 semiconductor. The other alternative method to extend the photocatalytic activity of TiO2 to visible light region is to dope this material with zink dioxide. A variety of metals and non-metals have been doped into TiO2 materials. Nowadays special interest has been focused on the preparation of titania mixed Pt and N because they show important photocatalytic properties as well as potential applications in the water splitting. The main of the obtained has been related to the creation of oxygen vacancies in the TiO2 crystalline structure which improve the photocatalytic activity. It is clear that production of hydrogen increases with the increase of Pt and N contents.
