NOVELTY - Preparation of lithium ferrite/reduced graphene oxide three-dimensional nano-composite absorbing material comprises adding surfactant to N,N-dimethylformamide, adding lithium ferrite (LiFe5O8) and graphite oxide, ultrasonic mixing, heating at 75-85 degrees C, adding hydrazine hydrate and methyl thioglycolate, reacting for 15-45 minutes, washing, and drying. USE - Method for preparing lithium ferrite/reduced graphene oxide three-dimensional nano-composite absorbing material (claimed). ADVANTAGE - The preparation method is simple, low cost, energy-saving, and has improved absorbing performance.
