overpotential การใช้

• Water oxidation catalysts minimize the overpotential and increase the reaction rate.
• The value of the charge transfer resistance changes with the overpotential.
• For a well designed cell the largest overpotential is the hydrogenase enzyme.
• The overall overpotential is the summation of many individual losses.
• Reaction overpotential is an activation overpotential that specifically relates to substrate concentration.
• Reaction overpotential is an activation overpotential that specifically relates to substrate concentration.
• Each step is associated with multiple forms of overpotential.
• The upper graph shows the current density as function of the overpotential ?.
• Significant charge overpotential indicates the presence of secondary reactions.
• "Voltage efficiency " describes the fraction of energy lost through overpotential.
• Platinum can be used as a catalyst to reduce the overpotential required for hydrogen production.
• In current cell designs, the charge overpotential is much higher than the discharge overpotential.
• In current cell designs, the charge overpotential is much higher than the discharge overpotential.
• Researchers demonstrated a potassium-air ( K " O2 ) battery with low overpotential.
• In a galvanic cell the existence of overpotential means less energy is recovered than thermodynamics predicts.
• This reaction requires some form of catalyst to avoid a large overpotential in the delivery of electrons.
• The exchange current density is the current in the absence of net electrolysis and at zero overpotential.
• Low overpotential and high catalytic activity of [ FeFe ] hydrogenases are accompanied by high O 2 sensitivity.
