▎ 摘　　要

NOVELTY - The material has an electric conduction substrate whose upper surface is arranged with a metal sulfide-graphene composite film. The metal sulfide graphene composite film is dispersed in solution to form a deposition film. A coating film is arranged on the upper surface of the electric conduction substrate by pressing the metal sulfide-graphene composite film. The electric conduction substrate is dried when coating process is completed. The electric conduction substrate is naturally cooled at room temperature to obtain an electrode of a dye-sensitized solar energy battery. USE - 2D metal sulfide graphene composite material for an electrode of a dye-sensitized solar energy battery. ADVANTAGE - The material avoids requirement of a bonding agent so as to prevent a material substrate from high temperature while removing impurity, thus maintaining feature and structure of the material substrate. The material satisfies rich nature and large-scale industrial production requirements. The material is simple to prepare, and has high catalytic property and wide application range. DETAILED DESCRIPTION - The metal sulfide is molybdenum disulfide, tungsten disulfide and tin sulfide. The electric conduction substrate is made of conductive glass, metal, copper and aluminum. An INDEPENDENT CLAIM is also included for a two-dimensional (2D) metal sulfide graphene composite material preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view of a 2D metal sulfide graphene composite material.
