NOVELTY - Preparing graphene oxide aerogel hollow microsphere comprises (1) preparing graphene oxide solution, adjusting its pH with dilute hydrochloric acid solution, (2) mixing graphene oxide with adjusted pH and oil phase, ultrasonically shaking vigorously to obtain a stable and rich emulsion, adding salt solution of metal ions, shaking well to make it evenly mixed, and allowing to stand until completing reaction, and (3) washing obtained emulsion with deionized water, centrifuging to obtain emulsion balls in upper layer, and drying to remove internal oil phase. USE - The method is useful for preparing graphene oxide aerogel hollow microsphere. ADVANTAGE - The method solves problem that existing preparation method of graphene oxide aerogel hollow microsphere needs high temperature and high pressure, increases cost, needs to add extra surfactant the template to modify or functionalize preparation process is complex.
