NOVELTY - Preparing nickel-gold-palladium alloy/graphene nanocatalyst, involves preparing graphene oxide by Hummers method, adding an appropriate amount of sodium dodecylbenzenesulfonate to graphene oxide and then ultrasonically dispersing to obtain dispersed graphene oxide gel, mixing chloroauric acid, palladium tetrachloride and nickel nitrate and then stirring to obtain mixed solution, adding solution to above gel and then adjusting pH, and transferring mixture to reaction kettle and then heating. USE - The method is useful for preparing nickel-gold-palladium alloy/graphene nanocatalyst, which is useful for fuel cell, and producing hydrogen gas from formic acid. ADVANTAGE - The method is capable of easily preparing nickel-gold-palladium alloy/graphene nanocatalyst with improved catalytic activity in an energy-efficient manner. DETAILED DESCRIPTION - Preparing nickel-gold-palladium alloy/graphene nanocatalyst, involves preparing graphene oxide by Hummers method, adding an appropriate amount of sodium dodecylbenzenesulfonate to graphene oxide and then ultrasonically dispersing to obtain dispersed graphene oxide gel, mixing chloroauric acid, palladium tetrachloride and nickel nitrate in a ratio of 0.10-0.50:0.25-0.45:0.25-0.45 and then stirring to obtain mixed solution having concentration of 1 mol/l, adding the solution to the above gel and then adjusting pH to 9-10 using sodium hydroxide, and transferring mixture to reaction kettle and then heating at 100-180 degrees C for 5-8 hours. An INDEPENDENT CLAIM is included for nickel-gold-palladium alloy/graphene nanocatalyst prepared by the method.
