Platinum catalyst supported by geopolymer for hydrogen reduction during radioactive waste storage was developed. It was confirmed by EDS measurements that platinum particles were supported on geopolymer matrix. From this results, it was suggested that the geopolymer has a hydrogen reduction capability.
