Global warming is primarily a problem of excessive carbon dioxide (CO2) in the atmosphere, which acts as
a blanket, trapping heat and warming the planet. One of the inevitable reactions during syngas (SNG)
production by the dry reforming reaction (DRR) of hydrocarbons is the deposition of carbon over the
catalyst which can be eliminated as anthropogenic CO2. This is the main obstacle for SNG production
during the DRR, diminishes the performance of the catalysts and enhances the CO2 formation which
leads to global warming. In this study, for the first time, we present a novel approach to use the carbondeposited
catalyst formed during the DRR as an effective electrode material for supercapacitor
applications. This disposable carbon-deposited catalyst shows 22 times higher capacity than the bare
catalyst and acts as a positive electrode for asymmetric supercapacitors. The fabricated supercapacitor
device works with an extended voltage of 1.6 V and exhibits an excellent electrochemical performance.
Moreover, serially connected supercapacitor devices could power up various types of LEDs and UV light
sensors.
