▎ 摘　　要

NOVELTY - A graphene-modified three-dimensional bicontinuous pore catalyst comprises graphene-doped aluminum-vanadium alloy where structure of graphene-modified three-dimensional bicontinuous pore catalyst is three-dimensional double continuous pore structure. The graphene-modified three-dimensional bicontinuous pore catalyst is obtained by mixing micrometer zinc powder modified by electrolysis with aluminum powder and vanadium powder, performing embrittlement and vacuum heating. USE - Graphene-modified three-dimensional bicontinuous pore catalyst used for preparing durene (claimed). ADVANTAGE - The product is stable and efficient and has uniform and wide distribution, high conversion rate, high selectivity and excellent catalytic performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (A) preparation of graphene-modified three-dimensional bicontinuous pore catalyst comprising adding zinc powder to alkali solution, heating, stirring until fully dissolved, adding graphene oxide solution, mixing, applying electrolysis voltage of 4-6 V and current density of 600-1800 A/m2, depositing graphene oxide-modified zinc powder on cathode, dehydrating, drying, placing graphene oxide-modified zinc powder in a ball mill with mixture of aluminum powder and vanadium powder, mixing, crushing, transferring to hydraulic press, rolling at room temperature to obtain graphene oxide-modified aluminum vanadium-based zinc alloy, performing embrittlement in low temperature environment, placing in tube furnace and heating at high temperature; and (B) application of graphene-modified three-dimensional bicontinuous pore catalyst comprising using methanol and 1,2,4-Trimethylbenzene at molar ratio of 1-3 as raw materials and reacting at 350-400 degrees C with flowrate of 25-30 ml/minute under the action of graphene-modified three-dimensional bicontinuous pore catalyst.
