▎ 摘　　要

We report the catalytic property of sulfonated reduced graphene oxide (SO3H-rGO) in the context of the additive esterification between carboxylic acids and olefins. The acid concentration in SO3H-rGO can be modified during preparation, the SO3H-rGO-5 at the optimal concentration of 2.66 mmol/g exhibits the highest catalytic activity in the additive reaction between acetic acid and isobutylene. The SO3H-rGO can exhibit better catalytic activity than two benchmark porous catalysts such as sulfonated activated carbons (SO3H-AC) and sulfonated SBA-15 (SO3H-SBA). Specifically, the superior performance of SO3H-SrGO observed for substrates with large steric hindrance (camphene and acrylic acid) suggests that its 2D sheet-like nanostructure can circumvent the mass transfer issue presented in conventional porous heterogeneous catalysts.
