A sulfonated reduced graphene oxide (RGO-SO3H) nanocatalyst was used to promote the reaction under solvent-free conditions. A range of trisphenol compounds were produced in the presence of this catalyst system in good to excellent yields. In the presence of this catalyst system, a less amount of phenol is required, which improves the environment through its capability in synthesis of trisphenols. The RGO-SO3H catalyst was reusable at least for 8 times in this process without a significant decrease in its catalytic activity.}, number={3}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Zekri, Negar and Fareghi-Alamdari, Reza and Badri, Rashid}, year={2024}, month={Feb.}, keywords={Sulfonated reduced graphene oxide, Solvent-free conditions, Trisphenol, 6-bis(hydroxymethyl) phenols} }
