  • Cyclic voltammetry (CV) measurements at room temperature to assess methanol concentration.
  • Comparative analysis of Pt/CNTs electrodes against Pt wire electrodes.
  • Investigation of methanol and formic acid mixtures in water for sensing.

    • Main Results:

    • The Pt/CNTs array electrode demonstrated high sensitivity for methanol detection in water.
    • The sensor successfully detected methanol concentrations in the range of 0.04 M to 0.10 M.
    • Incorporating formic acid as a co-electrolyte significantly enhanced the detection range, enabling measurements up to 1.0 M methanol concentration.

    Conclusions:

    • Vertically grown MWNTs micro-array with Pt/CNTs electrodes is a promising platform for sensitive methanol detection.
    • The developed sensor exhibits potential for integration into portable direct methanol fuel cell systems.
    • The use of formic acid as an electrolyte broadens the operational range of the methanol sensor.
