Abstract
Official abstract text for this publication.
A catalyst for generating hydrogen containing at least one composite metal selected from the group consisting of a composite metal of platinum and nickel and a composite metal of iridium and nickel, the catalyst being used in a decomposition reaction of at least one compound selected from the group consisting of hydrazine and a hydrate thereof; and a method for generating hydrogen, including contacting the catalyst for generating hydrogen with at least one compound selected from the group consisting of hydrazine and a hydrate thereof. Hydrogen can be efficiently generated with improved selectivity in the method for generating hydrogen that utilizes the decomposition reaction of hydrazine.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for generating hydrogen comprising contacting a catalyst for generating hydrogen with at least one compound selected from the group consisting of hydrazine and a hydrate thereof, wherein the catalyst is an alloy represented by Ni (1-x) Pt x (x=0.07 to 0.55). 2. The method according to claim 1 , wherein the alloy is prepared by adding a reducing agent to an aqueous solution containing a platinum compound, a nickel compound and hexadecyltrimethylammonium bromide to reduce the platinum and nickel ions. 3. The method according to claim 1 , wherein a temperature of the hydrogen generation reaction is 0 to 80° C. 4. A method for supplying hydrogen to a fuel cell, comprising supplying hydrogen generated by the method recited in claim 1 as a hydrogen source to a fuel cell.
