A METHOD FOR PREPARING HYDROGEN THROUGH DECOMPOSING SODIUM BOROHYDRIDE BY CATALYST

摘要

A method for preparing hydrogen through decomposing sodium borohydride by catalyst, comprises: disposing two electrodes in a vessel containing a solution of NaBH4, wherein one of the electrodes is positive electrode and the other is negative electrode; applying a direct current stabilized voltage supply to produce a direct current electric field between the two electrodes; removing sodium metaborate colloid produced from the decomposition of NaBH4, through moving the colloid to the positive electrode by electrophoresis under the effect of the electric field. The method can be applied in convenience, and ensure the decomposing reaction to be carried out in a relatively stable speed.
