Abstract
Provided is a porous graphene preparation method, comprising: under the function of a catalyst, conducting catalytic treatment on a biomass carbon source to obtain a first intermediate product, the catalyst comprising one or more of chlorides of manganese, iron compounds, cobalt compounds and nickel compounds; under protective gas condition, heating the first intermediate product from a first temperature to a second temperature and holding to obtain a second intermediate product; heating the second intermediate product from the second temperature to a third temperature and holding to obtain a third intermediate product; heating the third intermediate product from the third temperature to a fourth temperature and holding to obtain a fourth intermediate product; and cooling the fourth intermediate product from the fourth temperature to a fifth temperature and holding to obtain porous graphene. The porous graphene prepared via the method of the present invention has better electrical conductivity.
