NOVELTY - A catalyst comprises 0.2-8 pts. wt. component (A) comprising noble metal of group VIII element doped with ferric oxide or cobalt oxide as active metal, and 68-99 pts. wt. component (B) containing boron, nitrogen, sulfur and/or phosphorus modification elements and graphene as carrier. USE - Catalyst for liquid phase dehydrogenation of organic liquid hydrogen storage material (claimed). ADVANTAGE - The catalyst has high stability and dehydrogenation efficiency. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the liquid phase dehydrogenation catalyst, which involves treating graphene with modification elements to obtain component (B) as carrier, contacting salt solution of group VIII noble metal element with ferric oxide or cobalt salt solution to obtain active metal, and subjecting active metal and carrier to saturated impregnation method; and (2) liquid phase dehydrogenation method of organic liquid hydrogen storage material, which involves reacting the catalyst and organic liquid hydrogen storage material at 100-280 degrees C under pressure of 0-10 MPa and mass space velocity of 0.1-10 per hour to produce hydrogen gas and corresponding product.
