Abstract
Copper based derivatives such as CuO, CuS and CuSe
2
nanostructures were synthesized employing hydrothermal growth for clean energy production. Three different unique morphologies of CuO, CuS and CuSe
2
was observed respectively as hexagonal nanoplates, sharp edge rock like nanostructures and nanoflowers consists of well defined nanorods. Half cell electrochemical compartment was designed with the fabricated electrodes to explore oxygen evolution reaction (OER) activity. The highest electrochemical performance was interestingly achieved from cyclic voltametry (CV) profile for CuSe
2
electrode as 1144 F/g at 10 mV/s which is quite high specific capacitance for metal selenide candidate and also the higher OER activity of CuSe
2
electrode of 735 mA/g current density at 10 mV/s with low overpotential of 252 mV has been attained. The higher electron transportation mechanism and excellent stability was also achieved for copper selenide candidate that could be recommended as efficient OER active catalysts for future clean energy production applications.
