Figure 7.
System with a coronene unit with atom numbering at the central hexagon. Structures with optimized geometries for a coronene unit with C–Pt and Pt–Pt bond lengths: (a) 1Pt/CNOs, (b) 2Pt/CNOs, and (c) 3Pt/CNOs. (d, left) ADF STEM image of a cluster of three Pt atoms with distances in angstroms. The STEM data was filtered using the Richardson–Lucy algorithm implemented by Ichizuka to increase the accuracy in the measurement of the position of the atoms. DeConvHAADF is commercially available from HREM Research Inc. (www.hremresearch.com).
