Ionic Liquid–Mediated Selective Conversion of CO2 to CO at ...

Electroreduction of carbon dioxide (CO 2)—a key component of artificial photosynthesis—has largely been stymied by the impractically high overpotentials necessary to drive the report an electrocatalytic system that reduces CO 2 to carbon monoxide (CO) at overpotentials below volt. The system relies on an ionic liquid electrolyte to lower the energy of the (CO 2 ...


Potentiometric CO2 Sensor Using Li+ Ion Conducting Li3PO4 ...

Nov 16, 2005· Experimental. Planar type CO 2 sensors were fabricated by using thick film process for sensing and reference materials and thin film process for solid electrolytes. Li 3 PO 4 (Aldrich, %) thin films of 300 nm, 650 nm and μm thickness were deposited on Al 2 O 3 substrate by thermal evaporation. During deposition, the applied chamber pressure was 106 Torr and power was 10 A.
