Abstract:
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 m2
g− 1 and was employed as support in the
preparation of palladium-based (BC-TPEA@Pd) heterogeneous catalyst. The prepared BC-TPEA@Pd heteroge-
neous 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.
