▎ 摘　　要

NOVELTY - Preparing silver/reduced graphene nanocomposite material comprises (i) preparing graphite oxide mixed suspension: ultrasonic dispersing graphite oxide in deionized water/anhydrous alcohol mixed solution to form a suspension; (ii) preparing silver nitrate/graphite oxide mixed solution; and (iii) transferring the mixed solution to a hydrothermal reaction kettle and carrying out hydrothermal reaction. USE - The nanocomposite material is useful as biological antibacterial material, electrode materials and detection material. ADVANTAGE - The method is simple, economical, utilizes low toxicity agent, does not utilize reducing agent, has mild reaction conditions, and is environmentally friendly. DETAILED DESCRIPTION - Preparing silver/reduced graphene nanocomposite material comprises (i) preparing graphite oxide mixed suspension: ultrasonic dispersing graphite oxide in deionized water/anhydrous alcohol mixed solution to form a suspension; (ii) preparing silver nitrate/graphite oxide mixed solution: dropping aqueous ammonia to graphite oxide mixed solution, dissolved solid silver nitrate in the mixed solution, ultrasonic dispersing, forming sodium hydroxide solution, and dropping to silver nitrate/graphite oxide mixed solution to form a mixed solution; and (iii) transferring the mixed solution to a hydrothermal reaction kettle and carrying out hydrothermal reaction.
