摘要

The present work reports the synthesis of the BaCu2SnS4 ternary composite by implementing single-source precursor method using diethlydithiocarbamate ligand. BaCu2SnS4 was distinguished by the excellent band gap energy of 2.08 eV with the larger absorption hump at 434 nm. BaCu2SnS4 possessed hexagonal phase with smaller average crystalline size of 18.35 nm. In terms of the vibrational cross-linking, the metal sulfide bonds were confirmed located between 400 and 900 cm−1. BaCu2SnS4 ternary composite appeared as the non-uniform particles with abundant area for electrochemical reactions. The synthesized metallic sulfide has been an exceptional electrode material with the advanced specific capacitance of 807.88 F g−1. It exhibited distinctive redox activity. Minimal series of equivalent resistance (Rs) of 1.32 Ω was obtained for BaCu2SnS4 shown by the impedance data. The synthesized metallic sulfide has been shown to be an exceptional candidate for energy storage devices with specific power density of 601.4 W kg−1.
