Abstract:

Electrochemical Reduction of Carbon-Dioxide Using a Novel Electrode System
Newly discovered C60 carbon exhibits unique electrochemical behavior. Its properties
will be investigated to evaluate its ability to reduce CO2 electrochemically and
produce oxygen for air revitalization in manned space stations. Electrolytes appropriate
for the catalytic electrochemical reduction will be investigated. The electrochemical
behavior of C60 electrodes will be established using cyclic voltammetry. A two-ampere
laboratory electrochemical cell will be operated to establish the feasibility of
the concept. Phase I will establish the optimum cathode material, anode efficiency,
cell voltages, operating current density, and material balance by operating a five-ampere
cell for extended time periods. The definition of these variables will lead to the
determination of the economics of the overall process.
A new class of electrochemical reactions made possible by C60 could further expand
to other electrochemical synthesis reactions and fuel cells for power generators.
