Abstract
A process and apparatus for converting metallic elements to metallic oxalates in the presence of carbon dioxide includes two redox couple electrolyte solutions separated by a first membrane having photosensitizers. The carbon dioxide to be reduced is provided to a second membrane which is contiguous to one of the redox couple electrolyte solutions. The second membrane has photosensitizers and a catalyst. A non-aqueous electrolyte slurry, which includes a metal element, solvent and salt, is provided in a manner so that some of the slurry is in contact with the second membrane. Both membranes are illuminated and electrical voltage is provided across the electrolyte solutions and the electrolyte slurry in a manner so that there is one electrode in another electrolyte solution and another electrode in the electrolyte slurry so as to cause a reaction between the carbon dioxide at the second membrane and the electrolyte slurry to produce the metallic oxalate.
