Nanoparticle-Ligand Composite Catalyst Containing a Pseudocapacitive Interface for Carbon Dioxide Electrolysis (2020-042)
This invention is a nanoparticle-ligand composite catalyst that shows nearly unit CO selectivity (~99%) at lower overpotentials and achieves two orders of magnitude enhancement in CO production rate per catalyst surface area, making it ideal for companies generating large CO2 waste streams hoping to efficiently convert them into a potentially useful feedstock CO using renewables with minimal costs of materials and for product separation.
