▎ 摘　　要

NOVELTY - A nitrogen-doped nano-supported platinum-ruthenium alloy graphene catalyst comprises 30-50 %mass platinum, 10-30 %mass ruthenium and remainder of nitrogen-doped graphene having high specific surface area, and is prepared by heating graphene oxide in microwave under ammonia atmosphere, obtaining nitrogen-doped graphene having high specific surface area, adding polyol as reducing agent, carrying out microwave reflow process for depositing platinum-ruthenium precursor on nitrogen-doped graphene carrier, and heat-treating. USE - Nitrogen-doped nano-supported platinum-ruthenium alloy graphene catalyst for direct methanol fuel cell. ADVANTAGE - The nitrogen-doped nano-supported platinum-ruthenium alloy graphene catalyst has excellent conductivity and corrosion resistance, and high specific surface area.
