▎ 摘  要

NOVELTY - Preparation of multi-metal oxygen cluster-graphene foam compressible catalyst comprises adding graphene oxide, phosphotungstic acid, and Tween 80 (RTM: polyoxyethylene (20) sorbitan monooleate) into a beaker, vigorously stirring at normal temperature, freeze-drying for 3 days, annealing under argon/hydrogen gas atmosphere, soaking in methanol solution, and drying at 100 degrees C. USE - The method is used for preparation of multi-metal oxygen cluster-graphene foam compressible catalyst for preparing catalytic biodiesel (claimed). ADVANTAGE - The catalyst can effectively absorb the reactant and has quick separation with of reaction product. The method does not need mechanical stirring, saves energy, and reuses compressible catalyst. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of catalytic biodiesel comprising dropwise adding reaction solution into compressible catalyst, absorbing, and reacting at 60 degrees C for 6 hours.
