Abstract
A nanocomposite catalyst for use as an electrode in water electrolysis includes a cobalt triazole (Co-Tri) metal-organic framework (MOF), carbon quantum dots (CQDs), carbon nanosheets (CNs), and an ionically conductive polymer binder. The mass ratio of the nanocomposite catalyst includes cobalt triazole metal-organic framework to the carbon quantum dots is in the range of 1:2 to 1:4, and the mass ratio of the cobalt triazole metal organic framework to the carbon nanosheets mass ratio is in the range of 1:4 to 1:6. The nanocomposite catalyst includes current density less than or equal to (≤) −5 milliampere per centimeter square (mA·cm−2) at an applied potential of −100 millivolts (mV) when catalyzing the hydrogen evolution reaction (HER) in water electrolysis.
