The nature of rhenium in silica-supported Pt-Re clusters : synchrotron X-ray diffraction studies
Using synchrotron anomalous x-ray diffraction, the authors studied the structure of bimetallic Pt-Re catalysts with SiO[sub 2] as a support. The results reveal the presence of Re with a face-centered cubic structure in these catalysts. The authors propose that this form of Re is grown on Pt by an ep...

Summary: | Using synchrotron anomalous x-ray diffraction, the authors studied the structure of bimetallic Pt-Re catalysts with SiO[sub 2] as a support. The results reveal the presence of Re with a face-centered cubic structure in these catalysts. The authors propose that this form of Re is grown on Pt by an epitaxial effect. |
