Methanation of CO₂ is achieved by using photo generated hydrogen and catalyst particles loaded onto TiO₂ nanotubular template based on a patent pending technology. Our attempt is to:  1.) to evaluate the effectiveness of the ordered nanotubular TiO₂ arrays as a potential support for the catalysts and 2.) to verify that the photo electrochemically generated hydrogen is as effective as the hydrogen derived from any other source for methanation of CO₂.   CO₂ + air mixture is used for methanation reaction. Experiments are carried out at 200 – 350 ºC at different space velocities. The reaction products are analyzed using a gas chromatograph.
