N ‐heterocyclic carbene (NHC)‐palladium(II) complex (GO@NHC‐Pd) was synthesized on graphene oxide (GO) support via a simple and cost‐effective multistep approach. The spectroscopic, microscopic, thermal, and surface analyses of GO@NHC‐Pd confirmed the successful formation of the catalyst. The investigation of catalytic activity showed that GO@NHC‐Pd was very effective in Suzuki–Miyaura as well as Hiyama cross‐coupling. Being heterogeneous in nature, GO@NHC‐Pd was recovered after each reaction cycle easily and reused for up to nine and six cycles in Suzuki–Miyaura and Hiyama cross‐coupling, respectively, without significant loss of activity. Further exploration of the supercapacitor performance of GO@NHC‐Pd catalyst assembled in a two‐electrode cell configuration shown a maximum attained capacitance of 105.26 F/g at a current density of 0.1 A/g with good cycling stability of 96.89% over 2,500 cycles.
