▎ 摘　　要

NOVELTY - The method involves preparing graphene oxide by using a chloroform wet process. Platinum nano particles are deposited on a graphite fiber. The graphite fiber is placed in a glass instrument under room temperature. A molybdenum electrode and a saturated calomel electrode are provided as a counter electrode and a reference electrode. A graphene/platinum nano particles composite fiber is obtained by washing the electrodes with de-ionized water and drying the electrodes under vacuum condition. USE - Method for preparing graphene/platinum nano particles composite fiber electrode material. ADVANTAGE - The method enables achieving 8.45 percent of photo-electric conversion efficiency and providing high tensile strength. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view illustrating a method for preparing graphene/platinum nano particles composite fiber electrode material.'(Drawing includes non-English language text)'
