The photocatalytic conversion of carbon dioxide (CO2) to methanol was investigated. The procedure for the carbon dioxide conversion was carried out using a small scale filter type photocatalytic reactor. In conducting the experiments, carbon dioxide mixed with water vapor was discharged into the photocatalytic reactor in the presence of a catalyst and light irradiation from a UV lamp for conversion to methanol. The catalyst that were used for the experiments were titanium dioxide (titania) and copper-loaded titania which were impregnated on a ceramic filter that was initially treated with gamma-alumina which was a good catalyst support for the catalyst. SEM, XRD and particle size analysis was performed as a means of characterization of the catalyst. The effect of the flow rate of carbon dioxide on the conversion process using a UV lamp with a wavelength of 254 nm was studied.
