NOVELTY - Preparation of silver/graphene nanocomposites comprises weighing silver nitrate and organic fuel according to load quantity silver on graphene and preparation of target product; dissolving silver nitrate and organic fuel in small amount of water to obtain water dispersion containing 0.5-5.0 g/l graphene oxide; stirring for 15-90 minutes to obtain uniform dispersion; concentrating dispersion by heating to certain viscosity; putting concentrated product in heating furnace; and heating at 300-900 degrees C for complete combustion to obtain final product. USE - Preparation of silver/graphene nanocomposites. ADVANTAGE - The method has simple operation, has short reaction time, does not require addition of toxic reducing agent and stabilizer, achieves uniform dispersion of silver nanoparticles in graphene, and is fast and efficient. DETAILED DESCRIPTION - Preparation of silver/graphene nanocomposites comprises weighing silver nitrate and organic fuel according to load quantity silver on graphene and preparation of target product, in which organic fuel comprises glycine, urea and/or ethylene glycol, and number of moles of organic fuel is 0.5-5 times more than number of moles of silver nitrate; dissolving silver nitrate and organic fuel in small amount of water to obtain water dispersion containing 0.5-5.0 g/l graphene oxide; stirring for 15-90 minutes to obtain uniform dispersion, in which 10-100 mass% silver is supported in graphene; concentrating dispersion by heating to certain viscosity; putting concentrated product in heating furnace; and heating at 300-900 degrees C for complete combustion to obtain final product.
