Development of Approaches to the Formation of Platinum Sites with Desired Properties Using Layer-Structured Supports

Specific properties of layered double hydroxides (LDHs), directions of their use as supports and support precursors for synthesis of catalysts, and advantages of using such catalysts for various reactions were considered. The possibility to vary the chemical composition of LDHs (cationic layers, interlayer space) without destroying the structure of the material allows tuning their adsorption and acid-base properties and selectively realizing various mechanisms of anchoring the active component precursor toward preparing highly dispersed and stable supported catalysts. Approaches to the formation of supported platinum particles with desired properties through changing the anionic and cationic compositions of LDHs were proposed for the Pt/MgAl(M)-LDH system taken as an example.
