Abstract In the present study, a novel eco-friendly approach for the synthesis of hierarchically porous Mo 2 S 3 nanoflowers in cooking oil have been developed. This approach enables us to stabilize high temperature phase of Mo 2 S 3 even at 150 °C under hydrothermal condition in the environmentally benign solvent for the first time. The above low temperature approach leads to the formation of Mo 2 S 3 nanoflowers (diameter 0.5–2.0 μm and leaf thickness of ∼10 nm). Further electrochemical studies shows that the as-synthesized Mo 2 S 3 electrode shows high specific capacitance ∼248 F/g at a current density of 1 mA/g in Na 2 SO 4 electrolyte. The Mo 2 S 3 electrode showed high power and energy density of ∼15.98 kWkg −1 and ∼98.7 Whkg −1 respectively. Also, the Mo 2 S 3 electrode shows good electrochemical stability up to 3000 cycles. Thus from the above study, we have shown that the possibility of stabilization of metal chalcogenide in cooking oil and shown its high performance supercapacitors applications.
