Utilizing a facile and large-scale synthetic method at low temperature, a strong synergy was established between GCN and Co3O4, resulting in excellent performance as a bifunctional catalyst for OER and HER. The hybrid exhibits a low overpotential of 0.12 V and a current density of 147 mA/cm2 for OER, better than benchmarks IrO2 and RuO2. Furthermore, the hybrid demonstrates excellent performance for HER with a much lower onset and overpotentials, and a stable current density.

We report that molecular oxygen (dioxygen) can be activated to a hydroperoxyl (OOH) radical species by abstracting a hydrogen atom from H-containing co-adsorbates on Au nanoparticles. The OOH oxidant formed can undergo oxidation reactions directly through the end-on oxygen atom, or can dissociate into atomic oxygen and hydroxyl species for further oxidation reactions.
