NOVELTY - Preparation of encapsulated porous strong acid catalyst comprises dissolving transition metal salt in a polar inert solvent as 5-30 wt.% first solution, dissolving organic ligand in polar inert solvent as 10-50 wt.% second solution, dissolving arylsulfonic acid and co-agent salt in polar inert solvent as 10-30 wt.% third solution; mixing first and second solutions and reacting for 1-3 hours; adding third solution, adjust pH to 7.5-9.0, crystallizing at high temperature, and cooling to room temperature; adding graphene powder and templating agent, mixing, and crystallizing at high temperature; and filtering, washing with ethanol, drying at 100-120 degrees C for 8-12 hours, and shaping. USE - The method is used for preparing encapsulated porous strong acid catalyst. ADVANTAGE - The catalyst has high activity and dibasic selectivity.
