• Agricultural waste biomass-derived carbon-supported palladium-based (BC-TPEA@Pd) heterogeneous catalyst was newly developed through a green and sustainable approach by utilizing radish leaves as bio-waste resources and explored its catalytic activity in external base free Suzuki-Miyaura cross-coupling and energy storage applications. [Display omitted] •Biomass-derived carbon was prepared by pyrolysis of waste radish leaves and used as sustainable heterogeneous catalyst support.•Phytochemicals extract of radish leaves was used to reduce Pd+2 to Pd nanoparticles.•Basic extract of radish leaves mediated novel reaction protocol for Suzuki-Miyaura cross-coupling reaction was developed.•BC-TPEA@Pd catalyst delivered notable catalytic performance in Suzuki-Miyaura cross-coupling reactions.•BC-TPEA@Pd catalyst exhibited a specific capacitance of 129.36F/g. In the present work, we report the synthesis of low-cost mesoporous biomass carbon (BC) from waste radish leaves for the first time with a specific surface area of 703.99 m2g−1 and was employed as support in the preparation of palladium-based (BC-TPEA@Pd) heterogeneous catalyst. The prepared BC-TPEA@Pd heterogeneous catalyst was fully characterized by numerous analytical techniques. Moreover, we have developed a greener reaction protocol for Suzuki-Miyaura cross-coupling reactions using the basic extract of radish leaves with base/ligand/promoter/additives free reaction conditions. The newly developed reaction protocol offers greener reaction conditions, efficient, economical and highly recyclable methodology for the synthesis of substituted biaryls for commercial applications. Additionally, BC-TPEA@Pd catalyst shows high performance as supercapacitor electrode material in an aqueous electrolyte- based two electrode cell with a specific capacitance of 129.36F/g at a current density of 0.25 A/g and a 96.14 % of original capacitance retention after 2500 GCD cycles.
