1. Method of producing a gas sensor comprising the steps ofa. Positioning a sensor substrate (7) in a flame spray pyrolysis apparatus (1);

  • b. Generating an aerosol phase comprising sensing material nanoparticles by flame spray pyrolysis (FSP) of a precursor substance;

    c. Depositing the sensing material particles contained in the aerosol, in particular nanoparticles of the sensing material, onto the sensor substrate (7) directly from the aerosol phase to form a porous sensing layer (15) on the sensor substrate (7).
