Abstract

The invention discloses a method for preparing a three-dimensional order porous carbon / Prussian blue nanocomposite. Different from conventional reports, the three-dimensional order porous carbon / Prussian blue nanocomposite prepared by the method is based on a natural biomass original structure. The method for preparing the nanocomposite comprises steps of: preparing porous carbon through carbonized natural plants-ambary stems; and chemically synthesizing to obtain the three-dimensional order porous carbon / Prussian blue nanocomposite. The three-dimensional order porous carbon / Prussian blue nanocomposite has the following obvious advantages of simple preparation process, low prices, good catalytic performance and wide application to electrocatalysis.

Description
