Fig. 2: Phase analysis based on in situ SAED.
From: Operando TEM study of a working copper catalyst during ethylene oxidation
a–f In situ recorded SAED patterns and (g–l) azimuthal average (100 frames, 10 s) and time-integrated 2D diffraction patterns of Cu particles recorded at different temperatures in the gas mixture of C2H4, O2 and He (total pressure: 708 mbar; pO2 = 4.27 mbar, pC2H4 = 170.6 mbar).
