The Reduction of Carbon Dioxide through Electrochemical Reactions at the Plasma-Liquid Interface
Rebecca O’Toole
Global Market Demand
Greenhouse gases at high levels Global community taking steps to reduce carbon emissions Transportation contributes 14% of overall carbon emissions Demonstrates need for alternative energy sources
Issue of energy storage in automobiles?

Battery Technology
Heavily researched Major concerns: energy
density, safety, cost, charge-discharge rate lifetime
NiMH – Typically used in hybrid vehicles
Li Ion – Greater energy storage, safety and cost concerns http://www.theguardian.com/environment/2009/jun/10/prius-cars-solar
Charge Transfer Reactions
Reaction type occurring in batteries Movement of charged particles between
different materials Interface between different phases Typically solid-liquid Interface

Plasma Technology
Ionized gas that carry charge Usually operated at sub atmospheric pressures Limited applicability in charge transfer process
Mircoplasma operated at atmospheric pressure broaden research opportunities in charge transfer reactions
Plasma-liquid interface could replace solid-liquid interface Cost effective
Previous Research
Successful reduction of Ferricyanide to Ferrocyanide and hydrolysis of water at plasma-liquid interface
Conducted in chemical engineering department at Case Western Reserve University
Nature of reactions is still unclear More research is necessary for better understanding
Proposed Research
Reduction of carbon dioxide at plasma-liquid interface
Experimental set up based off previous research
Argon microplasma operated at atmospheric pressure
Expand understanding of charge transfer reactions
Increase development in battery technology
