Interface-engineered N-doped carbon dot/CdSe nanoconjugates as efficient Bi-functional electrocatalysts in alkaline media

Key Points

• The aim is to evaluate the performance of a new nanocomposite for electrocatalysis in alkaline conditions.
• Developed a nanocomposite using n-doped carbon dots and CdSe.
• Measured overpotential for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER).
• Assessed stability over a 50-hour period at specified current density.
• Achieved overpotential of 99 mV for HER and 170 mV for OER at 10 mA cm−2.
• Demonstrated prolonged stability for 50 hours.
• Observed a cell potential of 1.77 V at 10 mA cm−2 for overall water splitting.
