Together with the intrinsic merits of anticorrosion and cheapness of transition metal oxides, this composite system has shown its great potential as a practical photoelectrochemical material28. Discussion For a typical compact n-type semiconductor thin film photo- anode, the magnitude of photocurrent ...
Onset overpotentialPotential determining steprate determining stepEven at the best oxygen reduction reaction (ORR) catalyst, i.e., Pt-based materials, the ORR current is observed only below 1.0 V-RHE, indicating an onset overpotential higher than 0.20 V (0.25 V at pure Pt). Rational design of...
3 To drive high graphite lithiation rates, the requisite reduction overpotentials are sufficiently large to drop the graphite operating potential below 0 V versus Li/Li+, and hence, plating becomes thermodynamically possible. Beyond the kinetic surface overpotential, additional voltage drops due to Li...

Although wide attention has been paid to this topic, the fundamental understanding of Li plating onset is still under debate (concentration control or potential control?) due to overpotential coupling and highly localized deposition in porous electrodes. Here, the Li plating reaction overpotential and ...
Consequently, the CN photoanode exhibits a markedly low overpotential of 0.25?V versus reversible hydrogen electrode (RHE), which is comparable with the state‐of‐the‐art metal‐based photoanodes, an impressive photocurrent density of 116?μA?cm?2 at 1.23?V versus RHE in an alkaline solution ...

Both studies demonstrated that the passivation layer coating shifted the onset potential cathodically and enhanced the photocurrent at lower potentials. Aluminium is a dopant metal that can also act as an oxide passivation overlayer, thereby reducing the overpotential. Recently, Hwang et al. fabricated...
