description | The invention discloses a method for preparing classification porous carbon materials from fish scales. The method includes thoroughly cleaning the fish scales, then drying the fish scales and carrying out calcium removal treatment; carrying out low-temperature pre-carbonation; carrying out hydrothermal nitrogen doping treatment on pre-carbonated samples; ultimately forming pores by the aid of chemical activation processes and carrying out high-temperature carbonization and heat preservation procedures to obtain classification porous carbon. The classification porous carbon materials preparedby the aid of the method are of classification porous structures and comprise micropores and mesopores, the micropores are smaller than 2 nm, and the mesopores are larger than 2 nm and are smaller than 50 nm. The method has the advantages that the grass carp fish scales which are sold on markets are used as carbon sources, and accordingly the method is low in cost, short in technological period and extremely easy to opera |
