Supported noble metal catalysts have exhibited satisfactory catalytic performance in the dehydrogenation of liquid chemical hydrogen carriers, which supports play a paramount role conditioning nature active center and thus improving overall reactivity. Herein, specially designed nitrogen/amino co-functionalized carbon (NH2-NC) are prepared to load Pd nanoclusters for efficient formic acid (FA). The co-functionalization not only facilitates evenly dispersed with mean size 1.4 nm, but also provides beneficial metal-support interaction promote FA dehydrogenation. as-prepared Pd@NH2-NC discloses 100% conversion into CO2 H2 remarkable initial turnover frequency (TOFinitial) 4,892 h-1 low activation energy (Ea) 28.5 kJ mol-1 without additive at 298 K. work proposes strategy reasonably design heterogeneous may be extended develop other multi-functionalized different compositions nanostructures.
