Non‐Carbonized Pd Single‐Atom Catalyst Supported on Lignin‐Functionalized Phenolic Resin for Potent Catalytic Transfer Hydrogenation of Lignin‐Derived Aldehydes

Abstract Single‐atom catalysts (SACs) depend significantly on their support properties, and organic polymers have emerged as promising candidates due to their tunable physicochemical properties and diverse functional groups. However, the high‐temperature carbonization commonly required for conventional organic polymer‐supported SAC fabrication often leads to the loss of these functional groups, thus weakening metal‐support interactions and catalytic performance accordingly. Herein, we report a sustainable strategy to synthesize nitrogen‐functionalized lignin‐based phenolic resin (N‐LPR) supports for stabilizing atomically dispersed palladium (Pd) without carbonization. Using ammonia solution (NH 3 ·H 2 O) as…
