(537d) CO2 Photo-Electro-Chemical-Conversion- Characterization of Copper/TiO2

It is well known that one of the major options for reducing anthropogenic CO2 emissions in the near-term future is carbon dioxide capture and storage (CCS). The CCS technology includes separation and compression of CO2 from industry and power plants, and transportation of CO2 to a suitable storage site. The disadvantage of this concept is that CO2 compression to 2200 psia and transportation may be very expensive. Moreover, some countries may not have suitable geological formations for storing captured CO2. An interesting option for CO2 storage is its reuse, particularly, the production of ?synthetic fuels? by photo-electrochemical methods. The main challenge in the new approach to convert CO2 to CH4, CO, CH3OH, or formic acid is to increase the reaction yield ?Free? solar energy could drive the reaction to yield valuable synthetic fuels. In summary, Copper-doped-TiO2 was prepared by sol-gel method and characterized by XRD, UV-vis spectroscopy, Cyclo-voltammetry and Temperature programmed reduction. Results will be explained.
