Our news journalists obtained a quote from the research from Max-Planck-Institute for Chemistry, "A disordered over-layer decorating the surface of the nanoparticles was studied in a spatially resolved manner using ADF imaging and electron energy-loss spectroscopy. The analysis corroborated a partial decomposition of the intermetallic surface and formation of oxidic islands following exposure of the nanoparticles to ambient conditions. The direct imaging of the nanoparticles, the size of which predominantly falls into the sub-10nm range, revealed their morphologies and significant crystalline defects, including five-fold twinning."
According to the news editors, the research concluded: "The manifestation of the intermetallic compound in the nano-sized catalysts is intriguing from a crystallographic perspective and the observed deviations from the bulk crystal structure are of catalytic significance."
