Comment on "Extension of Rietveld Refinement for Benchtop Powder XRD Analysis of Ultrasmall Supported Nanoparticles" by J. Lipp et al. (Chem. Mater. 2022, 34, 18, 8091-8111)
Zbigniew Kaszkur
TL;DR
This paper critically evaluates and disputes the claims of a previous study on Rietveld refinement extension for nanoparticle analysis, providing principal arguments and atomistic simulation as evidence.
Contribution
It offers a critical analysis challenging the validity of prior claims about Rietveld refinement for ultrasmall supported nanoparticles.
Findings
The original claims are fundamentally flawed.
Atomistic simulation demonstrates the issues.
The critique questions the applicability of the method.
Abstract
The comment gives principal arguments proving that the claims given in the title of the commented paper and some its conclusions have to be wrong for principal reasons. An example illustrating the arguments is provided via atomistic simulation.
