A sensor comprising:
- a conductive region in electrical communication with at least two electrodes, the conductive region including a conductive material and a palladium-based catalyst material in contact with the conductive material, wherein the palladium-based catalyst includes a Pd(II) salt and a nitrite salt, a Pd(II) salt with a Cu(II) salt and a nitrite salt, and/or a Pd—Cu heterobimetallic complex and a nitrite salt.
A method of sensing an analyte, comprising:
- exposing a sensor to a sample, the sensor including:
- a conductive region in electrical communication with at least two electrodes, the conductive region including a conductive material and a palladium-based catalyst material in contact with the conductive material, wherein the palladium-based catalyst includes a Pd(II) salt and a nitrite salt, a Pd(II) salt with a Cu(II) salt and a nitrite salt, and/or a Pd—Cu heterobimetallic complex and a nitrite salt;
- and
- measuring an electrical property at the electrodes.
