Deoxygenative Reduction of Carbon Dioxide to Methane, Toluene, and Diphenylmethane with [Et2Al]~+ as Catalyst

摘要

Although nature uses CO2 as its main carbon source, the employment of CO2 as a readily available inexpensive feedstock for commodity chemicals is still in its infancy. Major industrial applications include the synthesis of urea, salicylic acid, and cyclic and polymeric carbonates. The reduction of CO2 to formic acid, methanol, or methane on an industrial scale is much less advanced. For example, there are only few pilot plants that are investigating and optimizing the heterogeneous catalytic reduction of CO2 with H2 to afford methanol.
