  • Publication number: 20200300806
    Abstract: Disclosed are improved micro-electrochemical sensor structures that uses cyclic voltammetry (CV) to perform electrochemical measurements on gaseous volatile organic compounds (VOC). The improved sensor structures include a Ag reference electrode layer and an adhesion SU-8 layer. Operationally, the oxidation of the Ag layer provides a reference potential that is used to determine the redox reactions occurring on the surface of Pt electrodes exposed to a flow of gaseous VOC. Experimentally, our improved sensor was used to detect methane dissolved in N2. The results show clear and reproducible oxidation signals that were attributed to the presence of methane in the gas flow. The position of this signal for methane was compared to CO, and was found to be clearly separated from it, proving the speciation capabilities of the sensor. In addition, our experiments showed that it is possible to use the current value to quantify the detected molecule in the gas flow.

  • Publication number: 20200127300
    Abstract: A catalyst structure includes: (1) a substrate; (2) a catalyst layer on the substrate; and (3) an adhesion layer disposed between the substrate and the catalyst layer. In some implementations, an average thickness of the adhesion layer is about 1 nm or less. In some implementations, a material of the catalyst layer at least partially extends into a region of the adhesion layer. In some implementations, the catalyst layer is characterized by a lattice strain imparted by the adhesion layer.
