NOVELTY - Preparing multilayer graphene/titanium dioxide material comprises e.g. washing the collected waste feathers, then rinsing with surfactant and deionized water and removing oil and sand impurities, (ii) preparing buffer solution, (iii) washed feathers cutting and placing coated polytetrafluoroethylene crucible lined, then adding tetrabutyl titanate and buffer solution, (iv) preparing grayish black powdery graphene/titanium dioxide material, and (v) grinding graphene/titanium dioxide material and rinsing with ethanol and deionized water, filtering and drying. USE - The method is useful for preparing multilayer graphene/titanium dioxide material (claimed). ADVANTAGE - The method has simple preparation process, low production cost; and the product has non-toxic, easy recycling and high catalytic efficiency. DETAILED DESCRIPTION - Preparing multilayer graphene/titanium dioxide material comprises (i) washing the collected waste feathers, then rinsing with surfactant and deionized water and removing oil and sand impurities, then placing the feathers at 60 degrees C for 12 hours, (ii) adding the 1 g potassium hydroxide into 100 ml beaker and then adding 50 ml anhydrous ethanol, stirring, dissolving to obtain buffer solution, (iii) 4 g plus minus 0.01 g washed feathers cutting and placing in 20 ml coated polytetrafluoroethylene crucible lined, then adding 2 ml tetrabutyl titanate, 10 ml buffer solution and stirring with rod sealed in the steel crucible, then placing at 220 degrees C, heating for 4 hours, (iv) removing the crucible and cooling the water bath to room temperature., then drying the resulting brown viscous liquid in corundum crucible, then placing in a tubular furnace at a rate of 10 degrees C/minutes under nitrogen atmosphere at 450 degrees C for 1 hours, natural cooling to room temperature, then removing the corundum crucible to obtain grayish black powdery graphene/titanium dioxide material, and (v) grinding the graphene/titanium dioxide material and rinsing with ethanol and deionized water, then filtering and drying at 60 degrees C for 12 hours.
