NOVELTY - Preparing graphene/zinc nanoparticle composite material comprises e.g. passing argon, dihydrogen and methane as reaction gas into double temperature zone tube resistance furnace, adding zinc acetate to high-temperature furnace tube furnace area, which is located on air flow direction of reaction gas, adding two-dimensional layered graphene as substrate to horizontal tube furnace low-temperature furnace area, which is located in direction of lower gas flow of reaction gas, reacting, turning off heating device after the reaction and then cooling argon, dihydrogen and methane gas. USE - The method is useful for preparing graphene/zinc nanoparticle composite material (claimed). ADVANTAGE - The material has simple preparation process and low cost, and is easy to operate and suitable for industrial production. DETAILED DESCRIPTION - Preparing graphene/zinc nanoparticle composite material comprises (i) passing argon, dihydrogen and methane as reaction gas into double temperature zone tube resistance furnace at a pressure of 100 Pa, adding 2 g zinc acetate to high-temperature furnace tube furnace area, which is located on air flow direction of reaction gas, adding two-dimensional layered graphene as substrate to horizontal tube furnace low-temperature furnace area, which is located in direction of lower gas flow of reaction gas and then reacting for 15 minutes, and (ii) turning off heating device after the reaction, cooling argon, dihydrogen and methane gas to room temperature to obtain graphene/zinc nanoparticle composite material.
