▎ 摘　　要

NOVELTY - Preparing boron-doped graphene zinc nano composite involves adding 2mg/mL of 20mL oxidized graphene suspension in to the reactor, adding 1M of 0.45ml tetrahydrofuran borane solution, stirring and reacted at 80 degrees C for 4 days. The obtained product is washed with tetrahydrofuran to obtain boron-doped graphene suspension. The 0.744g zinc nitrate and 0.4g sodium hydroxide are added to the boron-doped graphene suspension and subjected to hydrothermal reaction to obtain boron-doped graphene zinc nano composite. USE - Method for preparing boron-doped graphene zinc nano composite for catalyzing and and degrading waste water organic dye (claimed). ADVANTAGE - The method enables to prepare boron-doped graphene zinc nano composite improves light catalytic degradation efficiency, has good p-n heterojunction and high degradation efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for catalyzing and and degrading waste water organic dye, which involves: (A) using boron-doped graphene zinc nano composite as photocatalyst; and (B) catalyzing and degrading waste water organic dye.
