▎ 摘  要

NOVELTY - Preparing a honeycomb multi-stage pore nitrogen-sulfur-doped three-dimensional carbon material comprises slowly adding a homogeneous solution containing trimeric thiocyanate to an aqueous solution of graphene oxide in which melamine is dissolved, uniformly dispersing, carryingout the hydrothermal reaction at 120-220 degrees C, and calcining the hydrothermal reaction product at 300-500 degrees C. USE - The method is useful for preparing a honeycomb multi-stage pore nitrogen-sulfur-doped three-dimensional carbon material. ADVANTAGE - The method: produces carbon material having good rate performance as a lithium battery and a sodium battery anode, and a large specific surface area and a multi-stage pore structure are easy to achieve sulfur loading; the method is simple to process, and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for honeycomb multi-stage pore nitrogen-sulfur doped three-dimensional carbon material, is prepared by the above method.
