As a result of testing a series of catalysts based on iron-containing zeolites of different structural types (Y, M, pentasil), zirconium dioxide, and a binary support (zeolite + ZrO2) in the reaction of direct decomposition of nitrogen(I) oxide, we h

We used X-ray phase analysis, IR, X-ray photoelectron, and NMR spectroscopy to characterize a synthesized mesoporous material (Fe,Al)-MCM-41. As a result of a certain combination of structural, acidic, and oxidation–reduction properties of the surf

The possibility of making products of partial oxidation, alcohols and acids in particular, by the reaction of C3-C4 alkanes with nitrogen monoxide over oxide and zeolite catalysts is demonstrated. The most effective catalysts are CeO2 and Fe-TsVK. Th

The partial oxidation of C3 and C4 hydrocarbons by nitric oxide, in particular, their oxidation to alcohols, occurs on zirconium dioxide modified by various heteropolyacids (HPA). The catalyst activity depends on the amount of deposited HPA, while th

The acidic properties of the initial and copper-, cerium-, and cobalt-containing high-silica TsVK and TsVN zeolites of the ZSM-S type with SiO21A1203 ratios of 68 and 37, respectively, were investigated by IR spectroscopy and programmed thermal desor

An experimental study has shown that the addition of SO2 may either hinder or accelerate the selective catalytic reduction of NO by ammonia on oxide catalysts. The nature of the effect of SO2 depending on its concentration and temperature has been el

Brief consideration of new technical solutions for polarization optical transducers of quasi- static pressure proposed by the authors is presented hereafter. The advantages of MULTIMODE registration compared with ONEMODE registration were indicated.
