Реферат:
This study is a continuation of the work on the use of dynamic light scattering (DLS) for the analysis of active component particle sizes in supported catalysts. It was shown that the proposed STS (from solid to sol) approach is also applicable to supported catalysts based on sparingly soluble supports and nanocomposites. It was found that partial dissolution or destruction of a support with the formation of solution containing the desired nanoparticles is sufficient for effective DLS analysis. It was found that, under certain conditions, the effect of secondary aggregation of nanoparticles in solution can be observed in the course of catalyst dissolution, and this effect can prevent correct measurements. A method was proposed to avoid the secondary aggregation of particles in the course of the selective dissolution of a support. A good agreement between the results obtained by the new (DLS) method and traditional (TEM and XRD) methods was demonstrated.
