Preparation method of tin dioxide@oxidized bacterial cellulose/reduced graphene oxide electrode material

The invention discloses a preparation method of a tin dioxide@oxidized bacterial cellulose/reduced graphene oxide electrode material. The preparation method is characterized by comprising the following steps of: dissolving SnCl2 in concentrated hydrochloric acid to form a stable acidic SnCl2 solution; oxidizing BC slurry into OBC through 2, 2, 6, 6-tetramethylpiperidine oxide, and preparing an OBC solution; mixing the acidic SnCl2 solution, the OBC solution and a GO dispersion liquid in a hydrothermal kettle, performing stirring to form a uniform mixed solution, and carrying out hydrothermal treatment; and after cooling the hydrothermal kettle to room temperature, centrifuging a product, washing the product with water, washing the product with ethanol, and performing freeze-drying. The preparation method provided by the invention is simple to operate, environment-friendly and low in energy consumption; and the prepared SnO2@OBC/rGO nano composite electrode material has excellent electrochemical performance. 本
