METAL-FOAM CATALYST FOR HYDROGEN GENERATION FROM CHEMICAL HYDRIDE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/018993
Kind Code:
A2
Abstract:
The present invention relates to a method for manufacturing a metal-foam catalyst for hydrogen generation from chemical hydride, and more specifically, to a metal-foam catalyst for hydrogen generation from chemical hydrides, and to a method for manufacturing same. in which the manufacturing process for a metal-foam catalyst is simplified by using nickel (Ni), a constituent of a nickel metal-foam, as a catalytic precursor without using a separate catalytic precursor, which is a substance used prior to a production of a particular substance. The method according to the present invention comprises the steps of: forming nickel, which acts as a precursor, on the surface of the nickel metal-foam, by immersing the nickel metal-foam in an acid solution to use the nickel metal-foam as a support; reducing the nickel formed on the surface of the nickel metal-foam by immersing the nickel metal-foam in an alkaline boron hydride solution; obtaining a nickel-boron (Ni-B) metal-foam catalyst by cleansing the nickel metal-foam with distilled water, the Ni-B metal-foam catalyst being a compound in which nickel and boron from the boron hydride are combined; and dehydrating and calcinating the Ni-B metal-foam catalyst. Additionally, the present invention is characterized in that the metal-foam having a pore structure formed by one or more of shapes among a plurality of holes, open-faced elliptical shapes, crescent moon shapes, tree branch shapes, dumbbell shapes, cross shapes, and arch shapes, and thus the contact area with the catalyst is wide, and the catalyst is uniformly formed. Furthermore, the metal-foam catalyst is interconnected by one or more of the shapes as mentioned above. Accordingly, the present invention makes it possible to simplify the manufacturing process by not using a separate catalytic precursor, and to facilitate mass production, thereby lowering the manufacturing unit cost. Additionally, a large-pore structure of the metal-foam support allows the catalyst to be supported uniformly and stably, thus having the advantage of facilitating the movement of reactants to the surface of the catalyst and minimizing the loss of the catalyst during hydrolysis.
