▎ 摘　　要

NOVELTY - Synthesis of honeycomb three-dimensional graphene involves weighing graphene oxide (GO) in a beaker, adding distilled water and ultrasonically dissolving until the GO is completely dissolved, adding aqueous ammonia to adjust the pH, transferring the mixed solution to the reactor, hydrothermally reacting, cooling to room temperature to obtain black reduced graphene oxide (rGO) solid, centrifuging, washing, and freeze-drying. USE - Synthesis of honeycomb three-dimensional graphene in quasi-solid dye-sensitized solar cell (claimed) used in bioenergy, nuclear energy, ocean energy, hydrogen energy and solar energy applications. ADVANTAGE - The method enables synthesis of honeycomb three-dimensional graphene having loose porous structure, expanded specific surface area, and provides more contact area for the contact between the electrolyte and the electrolytic material. The quasi-solid dye-sensitized solar cell has photoelectric efficiency increased by 51.26%, and excellent electrocatalytic activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of honeycomb three-dimensional graphene in a quasi-solid dye-sensitized solar cell.
