▎ 摘  要

NOVELTY - Preparing solid catalyst comprises reacting graphene oxide and ammonia at 0-20 degrees C for 1-6 hours, carrying out suction filtration after completion of the reaction, washing the filtrate with deionized water, and drying in a vacuum oven at 4 degrees C for 6 hours with a pressure of 10 Pa for effectively immobilizing ammonium ion on surface of the graphene oxide. USE - The method is useful for preparing a solid catalyst for Knoevenagel reaction (claimed). ADVANTAGE - The method is capable of simply preparing the solid catalyst with high catalytic effect and long service life in an economical and eco-friendly manner.
