The reduction of carbon dioxide in aqueous solutions and the formarion of organic materials by means of Co/sup 60/ gamma radiation are reported. The investigation was carried out in a pH region from 2 to 10.9. From that it could be established that the yields of the organic materials such as aldehydes, formic acid, etc. as well as those of H/sub 2/O/sub 2/, H/sub 2/, CO, and O/sub 2/ depend strongly on pH value and radiation dose. The H/sub /2 yield reaches a maximum in the acid region (pH 2 to 4) and a dose of 2.3 x 10/sup 18/ ev/ml. In the presence of ferroions at pH 3.7 no maximurn was observed since it exerts a certain protective effect. The carbon monoxide, often an intermediate product in the reduction process, could be detected in the entire pH region from 2 to 10.9. At pH 7 oxygen was also identified and its yield increased with the pH value. The principal products of the carbon dioxide reduction scheme are CO, CO/sup -/, CO/sub 2/, HCO, and COOH. It was assumed that in the reduction process the lost electrons play a decisive role along with the free radicals and protons. A series of possible reactions in the reduction process are given.
