Abstract
A radioactive catalyst is disclosed which comprises a fine particle of semiconductor and a high radioactive platinum group element deposited on the particle of semiconductor. The radioactive catalyst serves as a source of radiation and also as a catalyst for oxidation-reduction reaction. By bringing the radioactive catalyst into contact with water, the water is decomposed by the oxidation-reduction reaction to produce hydrogen and oxygen.
Claims4
An oxidation-reduction method comprising providing a radioactive catalyst comprising a fine particle of semiconductor having a particle size of 0.1 to 10 .mu.m, and a radioactive platinum group element, which generates radiation energy of about 10.sup.5 to about 10.sup.6 eV, deposited on said particle of semiconductor, whereby said radioactive catalyst can serve as a source of radiation and also as a catalyst for an oxidation-reduction reaction;
- bringing the radioactive catalyst into contact with a fluid to be processed to produce electron-hole pairs in the semiconductor of said catalyst by radiation generated from said radioactive platinum group element deposited on said semiconductor particle;
- and thereby causing an oxidation-reduction reaction.
An oxidation-reduction apparatus comprising a container packed with a radioactive catalyst comprising a fine particle of semiconductor having a particle size of 0.1 to 10 .mu.m, and a radioactive platinum group element, which generates radiation energy of about 10.sup.5 to about 10.sup.6 eV, deposited on said particle of semiconductor, whereby said radioactive catalyst can serve as a source of radiation and also as a catalyst for an oxidation-reduction reaction;
- means for supplying a fluid to be processed into said container;
- and means for discharging products of oxidation-reduction reaction from said container.
