Abstract: Provided is a method for generating hydrogen at a desired rate, using a hydrogen storage material that can be stored and transported safely and inexpensively. The method according to the present invention for producing a silanol compound and hydrogen includes subjecting a hydrosilane compound and water to a reaction with each other in the presence of a solid catalyst to give a silanol compound and hydrogen. The solid catalyst includes hydroxyapatite and gold particles supported on the hydroxyapatite, where the gold particles have an average particle size of 2.5 nm or less. The reaction in the method according to the present invention for producing a silanol compound and hydrogen is preferably performed in an air atmosphere. The reaction in the method according to the present invention for producing a silanol compound and hydrogen can be performed with application of substantially no heat and no activated energy rays.

Abstract: Provided is a hydrogenation catalyst for an amide compound, containing hydroxyapatite and platinum and vanadium that are fixed on the hydroxyapatite, 15 to 80% of the surface of the platinum being covered with vanadium. The hydrogenation catalyst can promote a reduction reaction in which an amide compound is converted into an amine compound, can be used under mild conditions, and has such durability that the catalyst can be repeatedly used while retaining a high activity.
