The effect of nuclear radiation on the chemisorption of oxygen on Cr/sub 2/O/sub 3/, Cr/sub 2/O/sub 3/ - Al/sub 2/O/sub 3/, and Cr/sub 2/O/sub 3/ - SnO/ sub 2/ catalysts was studied. An iodometric method was used to measure the amount of chemisorbed oxygen. Simultaneously the increase in the catalytic activity of the catalyst in the decomposition of H/sub 2/O/sub 2/ was determined, It was found that the radiation present within a nuclear reactor promotes the chemisorption of oxygen on chromia (either pure or supported an Al/sub 2/O/sub 3/ or SnO/sub 2/) at temperatures at which such a chemisorption does not normally occur. The radiochemisorption of oxygen on chromia increases with the degree of dispersion of chromia on Al/sub 2/O/sub 3/ or SnO/sub 2/ and is accompanied by an increased catalytic activity of this catalyst in the decomposition reaction of H/ sub 2/O/sub 2/. It seems that radiochemisorption is largely due to the action of gamma rays and fast neutrons on the gas. (auth)
