The dehydrogenation of propanol 2 on sodium zirconium phosphates (NZP) with the composi tion Na 1 ⎯ 2x M x Zr 2 (PO 4 ) 3 (x = 0.125 and 0.25) in which Na + ions were replaced by M 2+ = Co 2+ , Ni 2+ , and Cu 2+ ions was studied. The experimental reaction activation energy E a decreased while transition through the T* = 310-340°C temperature; above this temperature, the electrophysical and crystallographic properties of the material changed. These changes were explained by the reversible transfer of Me 2+ ions from position M1 to M2 in the NZP lattice. Me 2+ centers with different alcohol adsorption forms at T < T* (one point) and T > T* (two point) participated in the dehydrogenation reaction. For the first form, E a and the logarithm of the preexponential factor linearly correlated with the ionic radius of M 2+ . The activity of M NZP catalysts altered in repeated experiments and in cases when the direction of temperature variations changed.

The catalytic activity of solid electrolytes from the family of complex bismuth vanadates Bi 4 V 2 -2x M 2x O 11 -δ (BIMEVOX) with V 5+ ions partially substituted by 3d metal cations was studied. In the transformations of isobutanol, it was found to depend on the crystal structure (α, β, γ Aurivillius phases), which changes at increased dopant ion contents (х М ). The highly conductive tetragonal γ phase was most active for all BIMEVOX oxides. The activation energy of the dehydrogenation of isobutanol Е increased linearly with the charge of the M n+ ion and activation energy of conductivity of the γ phase of BIMEVOX in the series Cu 2+ → Fe 3+ → Zr 4+ .

The catalytic properties of plasma-chemically and thermally treated Bi4V2-2xCu2xO11-δ with х= 0.00-0.16 (BICUVOX) in the transformation of isobutanol are studied. Plasma treatments lead to the total deactivation of the active sites of dehydration reaction, and the alcohol is converted with 100% selectivity into aldehyde. Activity of the dehydrogenation of alcohol after PCT increases in ~ 1.7 times on samples with xCu=0.04-0.06 (. phases) compared to the initial samples. Similar values which were found for the samples with xCu=0.0-0.06, including the double vanadate, suggests that PCT affects the ceramic matrix with Bi, O and V elements. Addition of small amounts of copper does not change this effect. Keywords: new materials, nano-design, perovskite, plasma-chemical treatment IntroductionLayered materials, with their structure consisting of stacked sheets, represent an interesting opportunity for developing new materials with a tailored nano-design, controlled accessibility to the sites and properties, tuneable pore size and volume, and high surface area. The use of layered materials (layered perovskite, anionic clays, pillared clays) in catalytic reactions is reviewed with emphasis on the possibilities offered from these catalysts to develop new processes for environmental protection, selective oxidation and refinery/biorefinery [1]. Of a great interest are bismuth vanadates belonging to the BIMEVOX family, for which oxygen-ionic conductivity is typical. In the crystal structure of bismuth vanadate Bi4V2O11-δ, cations Bi 3+ are in tetrahedral coordination; V 5+ cations, in octahedral coordination. Bismuth vanadates exist in several polymorphic modifications (α-, or monoclinic; β-, or orthorhombic; and γ-, or tetragonal). The tetragonal modification occupies a special place among bismuth vanadate polymorphic modifications due to its high transport characteristics. It is the γ-phase that has the highest conductivity and the lowest activation energy value [2,3], since all oxygen atoms in vanadium octahedra are involved in the diffusion processes. In polymorphic perovskites, α ↔ β and β ↔ γ phase transitions are observed as abrupt changes in the total conductivity with rising temperature. The catalytic activity of polymorphic copper-containing BICUVOX perovskites with the composition Bi4V22xCu2xO11-δ (х =0.00-0.16) in isobutanol transformations was studied in [4]. Plasma-chemical treatment (PCT) allows us to obtain completely new materials with widely varied surface properties, while preserving most properties of the original materials. This
