Abstract

The aim of our research is to convert CO2 into useful low-carbon fuels and industrial products such as CO, CH4, ethanol, and formate. We do this by using a nanostructured bimetallic catalyst as a working electrode. A three-electrode cell with a homemade cavity microelectrode is used to carry out electrochemical measurements with a potentiostat. A Pt wire serves as a counter electrode, an Ag/AgCl electrode acts as a reference electrode, and a Cu-Zn working electrode is where the electrochemical reaction occurs. If we change the concentration of the working electrode solution, it changes the selectivity of the products. During the electrochemical run, online Gas Chromatography was used to analyze the gas and the presence of CO and H2 was confirmed. After the potential (in the range of –2.2 V) was applied for 15, 30, 45, and 60 minutes, the electrolyte solution was analyzed using NMR. FTIR studies were performed to check the intermediate product formation for the used electrode and electrolytes. We are currently working on the characterization and quantification of the products. When we are able to increase the production of desired products, we will be able to reduce carbon emissions. The potential impact of our successful research on the world also includes improved air quality and stabilization of the currently rising temperatures.
