where η defines the overpotential, which is the difference between the electrode and standard potentials (η = E − E0),jdenotes the current density andbis the Tafel slope. Theoretically,simpleelectrochemical redox reactions can be described by the Butler-Volmer equation52: where α is...
And the cyano group and the vacancies of carbon and nitrogen in the prepared g-C3N4 structure not only can improve the separation efficiency and redox potentials of photogenerated charge carriers but also act as the active sites for the activation of essential reactive radicals [27], [31], [...
The nickel molybdate NiMoO4has gained significant attention in recent years as a proper electrode material for supercapacitor, due to its inexpensive cost, unlimited sources, great redox activity, well-defined redox performance and eco-friendly compatibility (Guo et al.2014; Yin et al.2015a). The...
Although solar-driven water splitting on semiconductor photocatalysts is an attractive route for hydrogen generation, there is a lack of excellent photocatalysts with high visible light activity. Due to their tunable bandgaps suitable for superior visibl
Excitingly, the coplanar oxidation, which has a great impact on the catalytic properties of NRR cata- lysts, can be solved by the potential difference between the redox potential (UR) and the limiting potential (UL) in this work. Among them, W2B2, Mo2B2 and Ta3B4 are ...
for which the flat band always lies 0.1 V below the conduction band (CB)56. Thus, CB and valence band (VB) positions of the Cu0.029-def-WO3vs. NHE (pH = 0) are established as −0.10 and 2.78 V, respectively57,58. Therefore, the potentials of VB and CB positions are...
·t, whereC0is the initial E2 concentration, andCtis the residual E2 concentration at reaction time t. The initial reaction rate constants are linearly correlated to the onset potentials of Mn(IV)/Mn(III) (Fig.7c and d). We also tested the longer-term reaction rate when E2 (10 µ...
If equilibrium exists between electrons and holes, then EF(e) = EF(h) = EF Similarly the electrochemical potential, Pf, of electrons in an electrolytic solution containing a redox system is defined in terms of the difference between the electrochemical potentials of the reduced and oxidized forms...
electrode may be coated, especially when it is ITO, with a thin layer of platinum, e.g. 5 to 50 angstroms for better charge transfer to the solid polymer electrolyte. When ITO is the counter electrode, the platinum is needed because ITO is an insert electrode with the iodine redox couple...
