▎ 摘　　要

NOVELTY - Preparing nitrogen-doped graphene folds, comprises (i) uniformly mixing graphene oxide solution and water-soluble nitrogen-containing compound, to obtain a mixture, and atomizing the mixture, and heating to volatilize solvent, to obtain a mixture of nitrogen-doped graphene oxide powder particles folds, and collecting the resulting graphene oxide powder particles, carrying out heat treatment under inert gas, to obtain the final product, where the heat treatment temperature is 150-1100 degrees C, and the resulting product has nitrogen content of 1-30%. USE - The method is useful for preparing nitrogen-doped graphene folds (claimed). ADVANTAGE - The method produces product having controllable degree of folding; and is simple, and economical.
