1. the preparation method of a magnetic porous carbon based on native cellulose, it is characterised in that comprise the following steps:

  • (1) native cellulose is placed in strong base solution, soaks 0.5 ~ 24 hour, be then washed to neutrality, filter, be dried,To activated cellulose;

    (2) being placed in the metal salt solution with catalytic action by step (1) gained activated cellulose, stirring reaction 0.5 ~ 24 is littleTime, through filtering, being dried, obtain cellulose/metal salt mixture presoma;

    (3) by step (2) gained cellulose/metal salt mixture presoma under reducing atmosphere 400 ~ 1000 DEG C calcining 0.5 ~12 hours, naturally cool to room temperature, to obtain final product;

    Wherein, the one during described native cellulose is cotton fiber, linen, straw, bagasse and paper.
