▎ 摘　　要

NOVELTY - The method involves preparing a three-dimensional (3D) graphene film on a conductive substrate. Graphene oxide is prepared based on an ultrasonic Hummer improving process. High temperature of a silencer furnace is reduced at 200- 1000 degree Centigrade. Oxidation graphite alkene powder and ethanol solution of mixture are mixed to carry out a milling treatment process. Single-layer graphene powder is mixed into organic solvent. A high-temperature hydro-thermal reaction process is carried out by sample using de-ionized water to obtain a copper-zinc-tin-sulfur/3D graphene composite film. USE - Copper-zinc-tin-sulfur and three-dimensional (3D) graphene composite film preparation method. ADVANTAGE - The method enables manufacturing the copper-zinc-tin-sulfur/3D graphene composite film with high conductivity, high specific surface area and high catalytic properties so as to save dye-sensitized light anode material resources of a solar battery based on topography of experiment and electrochemistry in an effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a copper-zinc-tin-sulfur and 3D graphene composite film.
