Silver Oxide-Graphene Sensor For Hydrogen Peroxide, Austin D. Scherbarth, L Stanciu
Silver Oxide-Graphene Sensor For Hydrogen Peroxide, Austin D. Scherbarth, L Stanciu
The Summer Undergraduate Research Fellowship (SURF) Symposium
A nonenzymatic, amperometric sensor for Hydrogen Peroxide (H2O2) was designed by drop coating glassy carbon electrodes (GCEs) with Silver Oxide (Ag2O). Combining Ag2O with Graphene Oxide and a polymer, PEDOT, was also attempted in order to increase stability and electrochemical properties. Using metal oxides along with Graphene Oxide for sensors has been done quite a bit, but Ag2O itself has not been research extensively. So, in order to produce the best H2O2 sensor, the configuration of all components had to be optimized. Three different Ag2O …

The Summer Undergraduate Research Fellowship (SURF) Symposium
The effective sensing of hydrogen peroxide is important for a variety of reasons. It can be utilized as a diagnostic tool for diseases like asthma; also, the sensing can be utilized in pharmaceutical and food production for quality control. The use of silver oxide nanoparticles with varying morphologies has not been investigated as a sensing agent for hydrogen peroxide in the past. The particles’ properties and ability to oxidize and reduce hydrogen peroxide suggest that they will be effective to create a sensitive sensor. The silver oxide particles were prepared through chemical reduction using varying molar ratios of reactants. The …
