Photoelectrochemical reduction of CO{sub 2} by silicate rock powders
- Mie Univ., Tsu (Japan). Dept. of Chemistry for Materials
The reduction in CO{sub 2} emissions by photoelectrochemical conversion of the CO{sub 2} to formic acid and methanol using silicate rock (andesite) powders suspended in water is presented. For photoelectrochemical reduction of CO{sub 2}, a homemade cell with a platinum and a copper electrode was used. 0.1 M KHCO{sub 3} solution was used as the electrolyte. In the photoelectrochemical reduction of CO{sub 2} with a copper cathode in the catholyte dispersing andesite powder, mainly formic acid, methanol, methane, ethylene, carbon monoxide, and hydrogen were produced. Consequently, it was found that this method using a copper electrode was effective for formic acid and methanol formations from carbon dioxide.
