摘要
The large-scale emission of carbon dioxide in to the atmosphere has wrought of the most serious and dangerous problems upon the earth, especially with regard to the devastating consequences of the greenhouse effect. The reduction and/or fixation of carbon dioxide can be said to be one of the most important areas of research in chemistry today, not only for solving the many urgent problems resulting from the pollution of the global environment but also for finding ways to maintain vital carbon resources. One of the best catalysts for photocatalytic reduction of CO2 + H2O to CH4 and CH3OH is TiO2. If some amount of metals (Ru, Rh, Cr, Co, Cu, Ni, Pt and Pd) is supported on TiO2, the selectivity will change. In the photocatalytic Reduction of CO2 with H2O, with addition some of Co, the d-character of the supported metal on TiO2 is decreased and the Fermi-level of the catalyst is raised, therefore production of methanol will increase.
