• Project: Identifying Intermediates in the Water Oxidation Cycle using FTIR
• PI: Dr. Dunwei Wang
• Summary: My project deals with the water oxidation cycle, specifically the oxygen-oxygen bond forming step. During this step, there are two proposed mechanisms: an intramolecular oxygen coupling reaction to form a bridged peroxide between two cobalt(III) atoms, the other a water hydrogen atom abstraction to form a cobalt hydroxide and a cobalt (oxy)hydroxide. Results from previous studies suggested that the mechanism of this step was dependent on the overpotential of the cell leading to the intramolecular oxygen coupling reaction to be favored at low overpotential, and the water hydrogen atom abstraction reaction to be favored at higher overpotentials. The goal of my research is to study the intermediates in these steps to identify the mechanics of this step.
• Created CoO_x films using galvanostatic electrodeposition
• Studied film stability and characteristics using cyclic voltammetry
• Ran in operando FTIR studies of electrode under various potentials to view potential-dependence of the O-O bond formation step

Events

Bettendorf Jr. High School STEM Expo:

• Setup 3D printers(Ceramic, FDM, and SLA) to demonstrate the creation of 3D elements
• This also inlcuded a Coffee station, 2D to 3D paper folding station, and a drone station

Setting Up the Raspberry Pi

• The operating system of the RPi(Raspbian) was setup and the instruction can be found at the following link:
