▎ 摘 要
NOVELTY - Preparing three-dimensional nitrogen/sulfur double-doped graphene aerogel, comprises subjecting graphene oxide, nitrogen source, sulfur grade alkaline compound to hydrothermal reaction at 120-220 degrees C, washing and carrying out freeze-drying. USE - The aerogel is useful as electrode material for oxygen reduction reaction (ORR) catalysis, photocatalysis, gas sensor or preparing lithium sulfur-battery (claimed). ADVANTAGE - The method has simple operation procedure, can accurately adjust nitrogen/sulfur content, and improves the performance of atom-doped graphene.
