▎ 摘　　要

NOVELTY - Electrolyte is claimed. The graphene/graphene oxide electrolyte obtained by adding glucose as reducing agent to aqueous graphene oxide solution. USE - The electrolyte is useful for anodizing nickel-titanium alloy (claimed). ADVANTAGE - The electrolyte is environmentally friendly and non-toxic. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing electrolyte, comprising adding glucose as reducing agent into aqueous graphene oxide solution and then perfroming reduction reaction at 80-120 degrees C for 5-12 hours to obtain final product; and (2) anodizing nickel-titanium alloy, comprising taking nickel-titanium alloy as an anode and a stainless steel as a cathode, and then anodizing at room temperature by direct current power supply and selecting the voltage from 40-90 V.
