The invention provides a preparation method of graphene aerogel, which comprises the following steps: immersing melamine foam into graphene oxide colloid, and drying it to obtain melamine foam material attached with graphene oxide; And carrying out heat treatment on the melamine foam material attached with graphene oxide to obtain graphene aerogel. According to the invention, cheap melamine foam is used as a structural template, and graphene aerogels with excellent performance are prepared by simple heat treatment; and the whole preparation process is short in time consumption, low in energy consumption, non-toxic and harmless, low in cost, suitable for industrial large-scale production, and has good adsorbability for oils.
