h-MoO3/Activated carbon nanocomposites for electrochemical applications.

MoO₃ nanorods were synthesized through the microwave method and the nanocomposites of MoO₃/activated carbon were prepared for supercapacitor and hydrogen evolution reaction (HER). The XRD pattern revealed that the prepared MoO₃ has a hexagonal phase (h-MoO₃). The as-prepared h-MoO₃ was composited with activated carbon (AC) and tested for supercapacitor studies. The fabricated supercapacitor exhibited an appreciable specific capacitance, power density, and energy densities. Further, dedoping of nitrogen in the doped AC creates defects on AC (DAC). These DAC/MoO₃ nanocomposites were prepared and tested for its electrocatalytic activity towards hydrogen evolution reactions. DAC/MoO₃ nanocomposite showed much higher electrocatalytic activity than the neat MoO₃.Microwave synthesized h-MoO₃ and active/defective activated carbon composites for supercapacitor and hydrogen evolution reactions [ABSTRACT FROM AUTHOR]
