Abstract
A method for preparing phosphorus-doped graphene using phosphorus-containing sludge and biomass, belonging to the field of solid waste resource utilization and environmental protection technologies, includes: performing a hydrothermal reaction with the phosphorus-containing sludge and the biomass to obtain a product, washing and drying the product to obtain phosphorus-doped hydrochar, and subjecting the phosphorus-doped hydrochar to a flash Joule heating treatment to obtain the phosphorus-doped graphene. The method for preparing the phosphorus-doped graphene by flash Joule heating is based on cheap and easily available phosphorus containing sludge and corn cobs as precursors. The high-quality phosphorus-doped graphene can be obtained by the flash Joule heating after in-situ phosphorus doping by a hydrothermal carbonization method. The method for preparing the phosphorus-doped graphene is controllable, fast, simple and efficient, which is beneficial to large-scale production and application.
