▎ 摘　　要

NOVELTY - Preparing flexible three-dimensional porous graphene electrode comprises (i) taking a piece of commercial graphene carbon paper, ultrasonic cleaning with acetone, ethanol, and distilled water for 15 minutes, removing and placing in the oven and drying, (ii) taking piece of glass, cut clean carbon paper into appropriate size (for example 1 x 2 cm) on the glass plate, coating commercial acrylic transparent adhesive tape on the carbon paper, push back and forth, and then removing transparent tape, and (iii) trimming non-sticky graphene tape part to obtain final product. USE - The method is useful for preparing flexible three-dimensional porous graphene electrode (claimed). ADVANTAGE - The method is simple and economical, and a large number of flexible three-dimensional porous graphene electrodes can be prepared with a small carbon paper.
