NOVELTY - Preparing a modified wood loaded with leaf-shaped graphene layer, involves: (i) cutting and processing the natural wood, placing in an alkali solution, heating in a water bath at 40-90°C, washing with water and drying to obtain pre-processed wood; (ii) soaking the pre-treated wood in a metal salt solution, fully combining the pre-treated wood with the metal salt solution, washing with water and drying to obtain wood modified by metal ion; (iii) processing the obtained metal ion modified wood and oxidized graphene aqueous solution by pressure impregnation, fully combining the aqueous solution of graphene oxide with the wood and standing to react and to obtain graphene oxide-modified wood; and (iv) freeze- drying the obtained graphene oxide modified wood to obtain a modified wood loaded with leaf-shaped graphene layer. USE - Method for preparing a modified wood loaded with leaf-shaped graphene layer that is utilized in photo-thermal conversion and photocatalysis field (claimed). ADVANTAGE - The method provides leaf-shaped graphene layer loaded modified wood with excellent light absorption and photothermal conversion efficiency, by a simple and efficient process utilizing wide source of materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the modified wood loaded with leaf-shaped graphene layer, which is prepared by the method.
