The Department of Energy is seeking sensors for energy-related pollutant gases in the atmosphere. This project will adapt amperometric gas sensors to make sensitive and selective measurements of these gases. The amperometric gas sensors will be built with new catalysts, and their controlled-potential operation will be demonstrated. Phase I will survey a series of electrode catalysts and measure gases using cyclic voltammetry and square-wave voltammetry of low-capacitance sensors. These sensors will result in pollution monitoring equipment that is less expensive and more portable than currently available options.
Commercial Applications and Other Benefits as described by the awardee: Less expensive methods of making air pollution measurement instruments, including hand held, portable devices should result.
