One-pot synthesis of a highly active single-atom Pd catalyst for the Heck reaction

A two-dimensional nitrogen-doped graphene-supported palladium single-atom catalyst (Pd SACs/NG) was successfully, precisely and concisely synthesized by a one-pot method. We report for the first time that 2D Pd SACs/NG oriented towards the Heck reaction achieved catalytic efficiency with a TON up to 133 256, significantly outperforming the commercial Pd(CH₃COO)₂ and Pd/C catalysts, surpassing previous reports.
