Characterization of the H2 sensing mechanism of Pd-promoted SnO2 by XAS in operando conditions.
The effect of Pd nanoparticles on the H2 sensitivity of SnO2 thin films was studied in real working conditions using X-ray Absorption Spectroscopy (XAS), electrical conductivity measurements and mass-spectrometry.
