(188ak) Titanium Dioxide Coated Glass Substrates for Efficient Hydrogen Production

Hydrogen production by photodecomposition of water into H₂ and O₂ has very low efficiency due to rapid reverse reaction and usually requires a slurry type of solution. This needs additional processing steps such as filtration and recycling of particles. Therefore, it is important to develop an efficient process for hydrogen production. TiO₂ coated surfaces could be an excellent technological alternative. In the current study, transparent TiO₂ deposited films were prepared on glass substrate via sol-gel method. The TiO₂ deposited film produced is characterized with X-ray diffraction technique, scanning electron microscopy (SEM) and UV-Visible optical fiber spectrophotometer to ensure optimum photocatalysis of TiO₂. Platinum will be deposited on the film by adsorption from aqueous solutions containing Na₂PtCl₄ followed by UV radiation. Hydrogen will be produced by the excitation of the coated film with UV light in a photo reactor with methanol as the reactant.
