Abstract
Activated carbon is effective as a catalyst for water decomposition when it is coated with a heat-resistant, oxidation-resistant film. The heat-resistant, oxidation-resistant film is formed from an inorganic material such as ceramic or metal, and/or an organic material such as an organic ion-exchange resin, a silicone resin or a fluororesin, and preferably contains oxide capable of decomposing hypohalogenous acid. Water can be chemically decomposed to give hydrogen by the use of the activated carbon.
Claims10
A method of decomposing water to produce a hydrogen halide and oxygen by reacting water with a halogen as represented by the chemical equations:
- H.sub.2 O+X.sub.2 .fwdarw.HX+HXO (1)
- HXO.fwdarw.HX+1/2O.sub.2 ( 2)
- wherein X is a halogen, in the presence of an activated carbon catalyst, and wherein the activated carbon is coated with a heat-resistant, oxidation-resistant film.
