The kinetics of electrochemical conversion of carbon dioxide to ethanol at a constant applied potential of -1.7 (Ag/AgCl) was demonstrated in two types of supported copper (I) oxide catalyst; namely (1) Cu2O nanoparticles pasted unto a Toray carbon fiber paper by a nafion binder, (2) electrochemically deposited Cu2O layer on a nafion-coated Toray carbon fiber paper. GC-FID measurements reported average formation rates of 2.5 � 0.2 and 0.9 � 0.2 �mol/cm2*hr with faradaic efficiencies of 5.1 � 0.7 and 2.2 � 0.5 % respectively for t = 110 minutes.
