REU (Research Experience for Undergraduates): Boston College

Summer 2019

• Project: Mechanistic Study of Intermediates in the Water Oxidation Pathway
• PI: Dr. Dunwei Wang
• Created heterogeneous CoO_x catalyst films using galvanostatic electrodeposition
• Determined a potential-dependent mechanism switch of the cobalt catalyst under steady-state conditions
• Analyzed intermediates in the water oxidation cycle on the cobalt catalyst in operando using FTIR at various potentials
• Used quartz crystal microbalance to study the potential-dependent effects of water adhesion onto the catalyst
• Final Presentation:
• Material and Methods: Materials and Methods Summary
• Important Research Articles:
  • Mechanistic Studies of the Oxygen Evolution Reaction by a Cobalt-Phosphate catalyst at neutral pH
  • EPR evidence for co(IV) species produced during water oxidation at neutral pH

Classes

Advanced Physical Chemistry

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:
