▎ 摘  要

NOVELTY - Ferric nitrate, zinc nitrate and citric acid are added to deionized water, and stirred to obtain a clear solution. Oxidized graphite alkene is weighed, and added to obtained solution, ultrasonically dispersed uniformly, and the obtained solution is added to atomizing device having tubular furnace with nitrogen or argon gas, and reacted to obtain black graphene/ferrite composite micro-spherical photocatalyst. USE - Manufacture of black graphene/ferrite composite micro-spherical photocatalyst used in wastewater treatment. ADVANTAGE - The method efficiently provides black graphene/ferrite composite micro-spherical photocatalyst having excellent adsorption function, by simple method. The black graphene/ferrite composite micro-spherical photocatalyst catalyzes organic molecule in visible light waveband, and can be recycled by means of magnetic separation.
