Investigation Of Underpotential Deposition Of Copper At Heated Gold Loop Screen-Printed Electrodes In A Variety Of Water Samples, Eun-Ju Lee
Legacy Theses & Dissertations (2009 - 2024)
To study the underpotential deposition (UPD) of copper, three different types of water samples (TraceSelect® Ultra-pure water, Indian pond water at University at Albany and tap water) are used at a heated gold loop screen-printed electrode (GLE), which is a new type of heated working electrode for voltammetry measurements that is able to directly detect the copper content in the water samples. The anodic stripping analysis of copper is performed with these gold loop electrodes at room temperature of 25 °C and electrode temperature of 80 °C at two different deposition potentials, -0.20 V and +0.10 V. Furthermore, the concentration …

Hydrogen fuel can provide an ideal carbon-free energy carrier wherever water is available, be that on Earth or throughout the solar system. The use of water electrolysis to split water molecules into contaminant-free hydrogen gas, suitable for use in fuel cells, and oxygen gas allows also for storage of excess electrical energy during periods of high production and low demand, and an easy path to release that stored energy when demand is high and active supply is low. However, liberating hydrogen from water is an energy-intensive process, and effective electrocatalysts that reduce the amount of energy wasted by the reaction …
