Relation between Crystallite Size and Dispersion on Supported Metal Catalysts
Abstract
Universal mathematical relations between the mean relative size of metallic crystallites ( d rel(VS) ) and their dispersion (FE) in supported metal catalysts have been developed. The relations are: d rel(VS) = 5.01/FE for FE < 0.2, and d rel(VS) = 3.32/FE 1.23 for 0.2 ≤ FE ≤ 0.92, where d rel(VS) = d VS / d at, ( d VS ) is the volume-surface mean diameter of an assembly of particles of different sizes, and d at is the atomic diameter of a given metal. It is shown that for FE > 0.2 the commonly used definition of d VS should be modified. The developed relations apply well to various thermodynamically probable crystallite shapes including fcc cubooctahedra of varying geometry, icosahedra, surface-reconstructed cubooctahedra, bcc rhombic dodecahedra, and hcp truncated bipyramids. The new relations are more precise than the commonly used equation d VS = a /FE, where a is a constant specific to a given metal.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
