  • Zinc oxide sulfur sensors and method of using said sensors
    Patent number: 8653839
    Abstract: A sensor is disclosed for determining a sulfur concentration in a liquid, such as a liquid fuel. The sensor includes a substrate that is at least partially coated with zinc oxide and, more specifically, zinc oxide microstructures. The zinc oxide microstructures have a crystal lattice structure that is oriented in the (002) plane, are oxygen-deficient and have a rod-like microstructure. If the substrate is conductive, it may be connected directly to a working electrode which is connected to a potentiometer which, in turn, is connected to a reference electrode. If the substrate is non-conductive, the conductive layer can be deposited on the substrate prior to deposition of the zinc oxide to form a working electrode. An application of a constant current (or voltage) to either electrode will result in a voltage across (or current flow between) the working and reference electrodes.
