▎ 摘  要

NOVELTY - Cobalt-based oxide loaded double-doped graphene catalyst comprises N, S double-doped graphene as a carrier supporting cobalt tetroxide nanoparticles and two coordination structures of Co-S and Co-N. USE - The catalyst is used as carbon monoxide oxidation catalyst (claimed) and in the fields of automobile exhaust gas treatment, sensors and petrochemicals. ADVANTAGE - The catalyst has excellent carbon monoxide oxidation catalytic performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing double-doped graphene catalyst, comprising soaking nitrogen-doped graphene in a chlorosulfonic acid solution for 1-2 hours, centrifuging the resulting reaction solution and freeze-drying to obtain a double-doped graphene carrier, preparing the cobalt salt solution, adding double-doped graphene into the cobalt salt solution, and carrying out solvothermal reaction at 140-180 degrees C for 6-8 hours, centrifuging, freeze-drying, and calcining under the protection of nitrogen.
