Abstract

The micro gravity effect on the product selectivity of electrochemical reduction of CCl2 F2 (CFC-12) was studied using the metal supported gas diffusion electrodes (GDEs). Under the micro gravity, the current efficiency for methane formation (the final product) increased, whereas that for CHClF2formation (a intermediate product) decreased at the Cu-supported GDE compared with the result under the normal gravity. This result suggests that the convection has an influence on the product selectivity for electrochemical reaction.
