摘要

Manganese oxide (MnOx) and multiwalled carbon nanotubes (MWCNTs) are intended to modify theGC electrode for oxygen evolution reaction (OER). Optimization of MnOx loading is carried out andthe deposition of 55 cycles was sufficient to obtain the highest activity toward OER. The stability ofthe catalyst is enhanced by the addition of MWCNTs. As a result, an amount of 22 kWh/Kg of O2 ofenergy is saved. Several techniques including cyclic voltammetry, linear sweep voltammetry,chronoamperometry, chronopotentiometry, field-emission scanning electron microscopy, and energydispersive X-ray spectroscopy will be combined to track the catalyst activity and to determine itsmorphology and composition.
