Step-by-Step Modeling and Experimental Study on the Sol–Gel Porous Structure of Percolation Nanoclusters

Non-conventional crystallization techniques have been developed in recent years. use primary structural elements (for example, clusters) rather than atoms and molecules. Modern nanomaterial science is going through great changes as an entirely new approach of non-conventional growth mechanisms emerging due to cluster coupling, catalyzing interest physics. The formation fractal percolation clusters has increased. We carried out step-by-step modeling experimental study the based on tin dioxide silicon formed by sol–gel technology. In this paper, aggregates (clusters) from sol particles SnO2 SiO2 modified models diffusion-limited cluster–cluster aggregation discussed. A model using simulated proposed. Experimental data structure porous nanocomposites are presented. particles, which also consist (the next step hierarchy), shown. propose a generalized hierarchical three-dimensional that allows calculating surface area, knowing sizes macropores taking into account micro- mesopores (sizes less few nanometers).
