The anodic oxidation of sulfur dioxide presents much interest in connection with the electrochemical manufacture of sulfuric acid and also with the problem of converting thermal energy into hydrogen chemical energy in a so-called thermoelectrochemical sulfuric acid cycle. The problem of this work was to ascertain the effect of some physicochemical properties of carbonaceous materials on their electrocatalytic properties in the electro-oxidation of sulfur dioxide. As objects of investigation we took carbonaceous materials of various structures: carbon cloths, graphite, and AG-3 activated carbon. The carbon cloths were prepared from viscous fiber and were heat-treated in the temperature range 800-2400/sup 0/. All catalysts were studied in the form of powders having a grain size less than 40 ..mu... The carbon cloths were preliminary ground in a mortar. To compare the electrocatalytic activity of the carbonaceous materials, we used a model floating electrode, in which a kinetic regime of the sulfur dioxide oxidation process is realized in a definite potential region on the disperse carbonaceous materials.
