http://everything.explained.today/Scherrer_equation/ WebbThe crystallize size of a metal particle in a supported catalyst is calculated from the Debye Scherrer equation, which is given at bottom. Please refer to that. Where, D = Diameter of the particle in nm K = Scherrer constant or shape factor of particle= 0.9 (assuming spherical particles)
WebbTHE accuracy of the familiar Scherrer equation, D= (IO..)j(ft cos6), (1) is limited by the uncertainties in K, the crystallite shape factor, and {3, the pure diffraction broadening. … Webb18 juni 2013 · The seed NPs were used in subsequent reaction steps to produce incrementally larger platinum NPs with average sizes of 25.7 ± 4.3, 31.3 ± 5.1, 39.8 ± 4.6 and 99.3 ± 3.7 nm. In general, the platinum NP size and morphology became visually more uniform, but display highly roughened surfaces.
