Abstract
Official abstract text for this publication.
Provided is a method for preparing a catalyst for a dehydrogenation reaction of formate and a hydrogenation reaction of bicarbonate, the method including: adding a silica colloid to a polymerization step of polymerizing aniline and reacting the resulting mixture to form a poly(silica-aniline) composite; carbonizing the corresponding poly(silica-aniline) composite under an atmosphere of an inert gas; removing silica particles from the corresponding poly(silica-aniline) composite to form a polyaniline-based porous carbon support; and fixing palladium particles on the corresponding polyaniline-based porous carbon support to prepare the catalyst.
First claim
Opening claim text (preview).
What is claimed is: 1. A catalyst for a dehydrogenation reaction of formate and a hydrogenation reaction of bicarbonate, the catalyst comprising: a polyaniline-based porous carbon support, in which palladium particles are fixed, wherein the catalyst further comprises a region in which nitrogen is included, and wherein the catalyst has a specific surface area of 500 to 1,200 (m 2 ·g −1 ). 2. The catalyst according to 9, wherein the polyaniline-based porous carbon support is a reaction product of a reaction of removing silica particles from a carbon composite produced via carbonization of a poly(silica-aniline) composite, and wherein the poly(silica-aniline) composite is a reaction product produced by mixing and reacting a silica colloid in a polymerization step of polyaniline. 3. The catalyst according to 9, wherein the catalyst has a spherical structure, and the region in which nitrogen is included has a pyridinized or pyrrolinized structure. 4. A method for releasing and storing hydrogen via a dehydrogenation reaction of formate and a hydrogenation reaction of bicarbonate using the catalyst according to claim 1 .
