The effect of the electrode surface roughness at low level of coarseness on the polarization characteristics of electrochemical processes

Influence of magnetic field on hydrogen reduction and co-reduction in the Cu/CuSO4 system

“…This means a reduction in overpotential, with a corresponding reduction in hydrogen reduction current and a change in copper growth mode, since the equilibrium has been moved to a regime where the deposits grow uniformly. Similar effects of convection are found for copper deposition from acid solutions [24,29].…”

“…The importance of this relies on the fact that mass transport-enhanced conditions promoted by magnetoconvection allow the system to operate at significantly lower overpotentials, which in turn leads to smother deposits and diminishes or inhibits hydrogen reduction. Popov et al recently reported, for the acid copper system, that convection induced by pulsed deposition can similarly improve surface roughness and improve current efficiency with view to energy saving [29]. The EQCM measurements also show that the magnetic field increases hydrogen current when the system is under potentiostatic control, reducing plating efficiency in that case.…”

The Cathodic Polarization Curves in Electrodeposition of Metals

“…If ζ different than unity is included in the derivation of the general polarization curve equation, simple analytical solutions are not available and numerical solutions are required. [19] with permission from Elsevier and Ref. [9] with kind permission from Springer)…”

Chemometric study on the electrochemical incineration of nitrilotriacetic acid using platinum and boron-doped diamond anode

“…Several earlier studies of the morphological and structural characterization of electrode material revealed the surface roughness played important roles in determining its electrocatalytic activity (Duo et al, 2003;Guinea et al, 2009;Luo et al, 2009). However, due to the limitations of the traditional roughness analyses, the accurate determination of surface roughness becomes particularly difficult in the case of real electrode materials (Popov et al, 2010). Alternatively, a novel mathematical tool named fractal geometry greatly simplifies the descriptive properties of surface morphology (Yadav et al, 2012).…”
