A shift to alternate energy sources is needed at the present time to address rising environmental concerns. The current research work aims to use a chemical‐free and green route to synthesize nanocomposite for their application as an electrode in the generation as well as storage of energy. Subsequently, the green synthesis of Bi2O3‐Sb2O3 nanocomposite was carried out using the leaf extract of Amaranthus viridis. The synthesized nanocomposite revealed a well‐arranged pattern of spherical nanoparticles with a crystal size of 29.43 nm and a band gap value of 2.5 eV. The hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) potentials of Bi2O3‐Sb2O3 were studied through linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS), whereas the energy storage studies were performed using cyclic voltammetry (CV) and galvanostatic charge discharge (GCD) techniques. The synthesized nanomaterial showed promising results for HER with an overpotential value of 205 mV as compared with OER, where an overpotential value of 450 mV was observed. However, excellent cyclic stability was witnessed for both reactions up to 1000 cycles. CV studies revealed an outstanding capacitance value of 348 F/g at a scan rate of 2 mV/s, whereas a specific capacitance of 269.5 F/g at a current density of 0.5 A/g was observed using GCD. The 15 h of electrode stability further endorsed the potential of synthesized material for energy‐based applications.

Energy‐efficient semiconducting BaS:MnS:Sb2S5 has been synthesized using a single source precursor method. The resulting dithiocarbamate metallic sulfide has an average crystallite size of 17.77 nm and a small band gap of 3.82 eV. A functional group investigation revealed the presence of several bonds, including the metal sulfide bond. This sulfide exhibited a double‐step thermal breakdown pattern. BaS:MnS:Sb2S5 particles were formed like cubes and tended to form cube‐like formations. The electrochemical charge‐storing behavior of BaS:MnS:Sb2S5 was investigated using a nickel foam electrode and a sulfide slurry. The fabricated electrode demonstrated a satisfactory capacity for charge storage, with a specific capacitance of 762.83 F g−1. This indicates a substantial amount of potential for long‐term energy storage utilizing electrodes. This electrode has a specific power density of 9084.78 W kg−1 and a low series resistance of (Rs) = 0.71 Ω, as per impedance measurements. Electro‐catalysis produced an OER overpotential and a corresponding Tafel slope of 233 mV and 157 mV/dec from the electrode. Conversely, for HER activity, the obtained overpotential and subsequent Tafel slope were 386 mV and 73 mV dec−1, respectively.

The nanocomposite material Sb2S3: SnS:MnS2 was fabricated by single precursor technique by using dithio‐carbamate ligand as Sb2S3:SnS:MnS2 (DDTC) complex. An internal and external look at the anatomy and activity of the substance was obtained by using a variety of analytical techniques like XRD, FTIR, UV‐Vis and SEM. Additionally, various electro‐analytical tools like LSV, CV, GCD and EIS were applied to confirm material's rich electro‐active capability for photoactive electrode. XRD revealed its average crystallite size of 12.33 nm with 82.8 % crystallinity. Optical characteristics represented describe effective semiconducting nature of nanomaterials with optimum band gap of 2.65 eV. By using electrochemical processes, LSV and CV demonstrated fertile opto‐electrical nature of Sb2S3: SnS: MnS2 (DDTC) material with specific capacitance, Csp, of 1080 F/g at scan rate of 2 mV/s. With a high specific power density of 2656 W/kg, the GCD technique attempted to validate the nature of the material as an electrode with a good charge‐discharge mechanism. In EIS, low series resistance, Rs=0.73 Ω, was observed to be very beneficial argument in validating the nanocomposite synthesized in this research project as effective and low‐cost material which can be applied in different energy producing and storing devices like solar system and super‐capacitors etc.
