Photocatalytic reduction of carbon dioxide (CO2)

C.S. Jeffrey,     Wu, Department of Chemical Engineering, National Taiwan University, Taiwan

Abstract:

One of the best means of solving the carbon dioxide (CO2) problem is to photocatalytically convert the CO2 to hydrocarbons using solar energy, a process which simultaneously generates renewable energy. This chapter discusses the photocatalytic reduction of CO2 using either artificial light or sunlight and presents the fundamental mechanism of CO2 photoreduction. An optical- fiber reactor has been designed that transmits and spreads light uniformly inside the reactor. Methanol is the main product from Cu- or Ag-loaded TiO2, and methane and ethylene are produced from Cu–Fe- loaded TiO2–SiO ...
