Fig. 4: In situ nano-BCDI for strain analysis on individual NPs during eCO2RR using coherent X-rays at the P10 beamline (PETRA III) at Deutsches Elektronen-Synchrotron (DESY, Germany).

Representative diffraction patterns acquired at varying potentials on an individual Cu0.88Ag0.12 NP are illustrated. Red arrows highlight slight changes in the acquired fringe patterns observed under more negative potentials. Rocking curve (RC) parameters are given in the SI. Axis1 and axis2 correspond to the horizontal and vertical axes of the bi-dimensional detector, respectively. Note that all potentials were converted to the RHE scale and 100% iR-corrected.
