abstract = {The intermetallic compound ZnPd has demonstrated excellent
catalytic properties in methanol steam reforming. While it
is known that defects and microstructures influence the
catalytic properties, little is known about the defects
occurring in ZnPd. Due to recent advances in synthetic
methods, coarse-grained ZnPd samples are accessible. This
enables the detection and investigation of twinning in ZnPd
by studying the twinned regions from the macroscopic scale
by polarised light and electron backscattering diffraction
(EBSD) down to the atomic scale by high-resolution
transmission electron microscopy (HR-TEM). Twinning occurs
in {101} and is coupled with a change in the c/a ratio in
the vicinity of the twin boundary. Quantum chemical
calculations result in only very small energy differences
between the ideal and the twinned structure, explaining the
experimentally observed thermal stability of the latter. The
chemical bonding was investigated by the electron
localizability indicator (ELI) and compared to the one in
the ideal structure. The results confirm twinning along the
{101} plane and demonstrate the high stability of the twin
boundaries after formation.},
