Fig. 2: Correlation between structural dynamics and catalytic activity.
From: Redox dynamics and surface structures of an active palladium catalyst during methane oxidation
In situ observation of the catalyst dynamics at 350 °C (a, b) and 550 °C (e, f) in the reactive atmosphere (p(CH4) = 39.5 mbar, p(O2) = 8.8 mbar and p(He) = 131.7 mbar). c Difference between images on (a, b). g Difference between images on (e, f). d, h Electron diffraction patterns recorded at 350 °C and 550 °C, respectively. (i–l) Particle dynamics observed at a medium magnification at 550 °C. m MS data recorded during operando TEM experiments. Electron dose rates for (a, b), (e, f), and (i–l) were 250, 700, and 700 e·nm−2 s−1, respectively.
