Figure 2. Experimental approach used to estimate the catalysts structural disorder through the extraction of microstrain from the synchrotron WAXS patterns.

Figure 2

a) Typical experimental WAXS patterns measured on structurally-disordered and structurally-ordered catalysts (here, Hollow PtNi/C and Cube Pt/C, respectively). The patterns are plotted as a function of the momentum transfer Q and b) possible sources of microstrain in bimetallic nanocatalysts (grain boundaries, inhomogeneous alloying or (electro)chemical surface destruction). The insert in a) shows the influence of macrostrain and microstrain on the position and the broadening of the WAXS reflections.
