Abstract
Ruthenium(0) nanoparticles were successfully prepared on the surface of ceria (Ru0/CeO2) and used as catalysts on glassy carbon electrode (GCE) in oxygen evolution reaction (OER) from water electrolysis at room temperature. Ru0/CeO2 on GCE exhibits high catalytic activity for OER in alkaline solution. It provides a low onset potential of 1.57 V vs. RHE and low overpotential of 420 mV vs. RHE to reach a current density of 10 mA cm?2. Ru0/CeO2 on GCE shows no change in the onset potential value even after 6.1 h electrochemical measurement in OER.
Microsoft is Ending Support for Windows 7
