Effect of sodium dodecyl sulfate on the rate of hydrogen evolution at a cathode

Fabrication and Performance Evaluation of Pd‐Cu Nanoparticles for Hydrogen Evolution Reaction

“…However, a distinct behavior is observed in the presence of surfactants. In these cases, surfactants lower the surface tension and stabilize the gas bubbles and improved the catalytic activity rather than blank solution …”

“…The molecules can be confined on the electrode surface through variety of interactions such as electrostatic, coulombic, hydrogen bonding, or non‐covalent attachments between their hydrophobic tails or hydrophilic head groups . El‐Batouti studied the effect of sodium dodecyl sulfate (SDS) on the mass transfer performance of an H 2 ‐evolving Hg cathode . They found that a decrease in the solution surface tension caused by SDS gives rise to early detachment of small H 2 bubbles from the electrode surface.…”

Electrochemical recovery of copper complexed by DTPA and C12‐DTPA from aqueous solution using a membrane cell

“…Moreover, the hydrogen gas bubble coverage could affect the mass transport of copper complexes negatively via water reduction at the cathode, but is not taken into account in Equation . The bubble coverage is strongly dependent on the solution flow rate, the current density, the nature of the gas, and the material and surface condition of the electrode, as well as solution composition and concentration . However, the gas evolution at the electrode has been found to accelerate mass transfer in several ways, as described in four proposed models: the microconvention model, the penetration model, the hydrodynamic model, and the surface renewal model .…”

However, the gas evolution at the electrode has been found to accelerate mass transfer in several ways, as described in four proposed models: the microconvention model, the penetration model, the hydrodynamic model, and the surface renewal model . In addition, it is widely accepted that the increase of bubble coverage on the cathode gradually shadows the active electrode surface .…”

MEMS electrolytic inchworms for movable neural probe applications

“…The topic of electrogenerated bubbles has been investigated by many researchers, for example [88][89][90][91][92][93][94]. The behavior of bubbles on gas-evolving electrodes is of great interest because it significantly affects the mass transport.…”
