A new method for determining the concentration of internal defects in powder catalysts has been developed at Novosibirsk State University (NSU). This was reported by the university's press service.
As part of my project, we proposed a method that allows us to analyze the number of defects in the sample itself based on the diffraction data obtained during the study. It is very important for chemical researchers, since the number of defects in the structure of the sample significantly affects its catalytic activity.
The chemical structures under study are of interest to specialists due to their potential use as superconductors, catalysts, and thermoelectrics. The content of defects in these materials can become a key parameter for "tuning" their functional properties.
The main feature of the new method is the study of the structure using X-ray radiation. It is expected that the research results may find application at the station of the under-construction synchrotron "Siberian Ring Source of Photons" (CSCP SKIF).
And if in laboratory conditions it takes about an hour to take just one X-ray, then at SKIF this manipulation, together with the analysis of the data obtained, will take only a few minutes, which will facilitate the work of scientists in finding new effective materials.
The new method will allow determining the presence and structure of defects for catalyst samples obtained in different ways.
