Comparative Analysis of Physicochemical Properties of Rutile TiO2 with Hierarchical 3D Architecture Prepared by Liquid Hydrolysis of TiCl4 and Hydrothermal Method

Autor: N. V. Shikina, S. A. Yashnik, A. V. Toktarev, A. V. Ishchenko, V. A. Ushakov, M. S. Mel’gunov, Z. A. Mansurov, Z. R. Ismagilov

Publikováno v: Eurasian Chemico-Technological Journal, Vol 22, Iss 3 (2020)

TiO2 (rutile) samples with a hierarchical 3D nanostructure of the particles were synthesized by two methods: liquid hydrolysis of TiCl4 at 90 °С and atmospheric pressure; hydrothermal synthesis from TiCl4 at 160 °С and different [H2O]/[Ti] ratios

Development of Highly Efficient Hydroisodeparaffinization Catalysts Based on Micro-Mesoporous SAPO-31: New Approaches in the Synthesis of SAPO-31 and the Preparation of Bifunctional Catalysts

Autor: Gennady V. Echevsky, Aleksander V. Toktarev, Evgeny G. Kodenev, Dmitry G. Aksenov

Publikováno v: Catalysts; Volume 13; Issue 5; Pages: 810

A method is proposed for the synthesis of micro-mesoporous SAPO-31 with a high external surface area and large mesopore volume using tetraethoxysilane as a source of silicon. The synthesis of SAPO-31 is based on the principles underlying the Stöber

n-Butane transformation on Zn/H-BEA. The effect of different Zn species (Zn2+ and ZnO) on the reaction performance

Autor: Sergei S. Arzumanov, Alexander V. Toktarev, Dieter Freude, Zoya N. Lashchinskaya, Jürgen Haase, Alexander G. Stepanov, Anton A. Gabrienko

Publikováno v: Journal of Catalysis. 391:69-79

Using solid-state 1H and 13C MAS NMR spectroscopy, the performance of H-BEA zeolite, modified with either Zn2+ cations (Zn2+/H-BEA) or ZnO clusters (ZnO/H-BEA), has been investigated with respect to n-butane transformation by aromatization and hydrog

Mechanism of H/D Hydrogen Exchange of n-Butane with Brønsted Acid Sites on Zn-Modified Zeolite: The Effect of Different Zn Species (Zn2+ and ZnO) on the Activation of Alkane C–H Bonds

Autor: Anton A. Gabrienko, Alexander G. Stepanov, Jürgen Haase, Sergei S. Arzumanov, Alexander V. Toktarev, Dieter Freude

Publikováno v: The Journal of Physical Chemistry C. 124:20270-20279

With the aim of clarifying the effect of Zn species of different nature (small clusters of ZnO and Zn2+ cations) on the activation of alkane C–H bonds by Zn-modified zeolite, the mechanism of the H...
