NOVELTY - Preparing middle hole of the high ratio surface active graphene, involves peeling off the graphite oxide graphene obtained with phosphoric acid solution impregnation, and then activated to obtain the middle hole of the high ratio surface active graphene through washing, filtering and drying. USE - For preparing middle hole of the high ratio surface active graphene useful for super capacitor, fuel cell, nano-electronic device, high frequency circuit, sensor, electronic gene sequencing and reduce noise. ADVANTAGE - The method has low production cost, simple technical steps, less production equipment corrosion; prepares graphene has high specific activity, good conductivity, good chemical stability and proper hole structure; and remarkably improves the capacitance and cycle performance of the capacitor.
