Abstract

This review article covers recent developments in X-ray and neutron powder diffraction with an emphasis on the complementary nature of these two condensed matter probes. After a short summary of the basics of X-ray and neutron scattering, examples of ‘mesoscopic’ structure investigations (i.e. particle size, strain) are presented followed by state-of-the-art combined neutron and X-ray high-resolution powder diffraction studies of ‘real’ catalysts. Neutron and X-ray powder diffraction studies in magnetic fields are highlighted and the reemergence of the total scattering approach using pair-distribution function (PDF) analysis within the context of ‘nanocrystallography’ is discussed. Modern examples of high-pressure crystallography using X-ray and neutrons are given. A short outlook considers future directions in light of nanoscience and new X-ray and neutron sources.
