▎ 摘　　要

NOVELTY - Reducing graphene oxide comprises adding graphene oxide to natural organic humus solution, ultrasonically dispersing at 20-40 degrees C, subjecting to light source irradiation under an inert gas, continuously stirring until the color of the solution is substantially constant, then centrifugally separating to obtain a product, and then freeze-drying the product to obtain re-dispersion reduced graphene powder. USE - The method is useful for reducing graphene oxide (claimed). ADVANTAGE - The method: has mild reaction condition and low energy consumption effect; can avoid the damage to graphene structure produced by the existing technology due high temperature or high energy ultraviolet ray produce; adds natural organic humus, which is non toxic to environment; promotes graphene dispersion; protects graphene structure; is simple, green and environmentally friendly; has controllable degree of reduction; and produces the product, which is suitable for photoelectric material field.
