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.
