    Description / Table of Contents: Abstract С использованием алгоритма на основе математической модели структурной химии разработан подход для оценки каталитических свойств атомов метомов металлов в процессе гидрирования окиси углепода в газовой фазе. Получены структуры и энергетические характеристики промежуточных соединений и возможиых продуктов в процессе каталитического гидрирования окиси углерода до C1 и C2-органических соединеиий. Определены металлы, катализирующие реакци№ до образоваия различнях продуктов.
    Notes: Abstract An approach to determine the catalytic properties of metal atoms for the hydrogenation of CO in the gas phase is suggested. This approach has been developed using an algorithm based on a mathematical model for structural chemistry. Structural and energetic characteristics for intermediates and possible products of the catalytic hydrogenation of CO to C1 and C2 organic compounds and metals established as catalysts for the formation of various products are presented.

    Liquid-phase oxidation of propylene to propylene glycol acetates over Pd/C and Pt−Pd/C: Effect of platinum on catalyst activity and metal dispersity (1992)

    Description / Table of Contents: Abstract Изучена кинетика окисления пропилена в пропиленгликоль и его ацетаты в уксуснокислых растворах нитрата лития на каталиэаторах Pd/C и Pd−Pt/C. Катализаторы исследованы методами РФА и электронной микроскопии. Показано, что введение в состав катализаторов платины приводит к увеличению дисперсности металлических частиц и стабильности катализаторов, но не влияет на природу поверхностных центров, активных в реакции окисления пропилена.
    Notes: Abstract Kinetics of oxidation of propylene to propylene glycol and its acetates in acetic acid solutions of lithium nitrate over Pd/C and Pd−Pt/C catalysts has been studied. Catalysts were investigated using X-ray phase analysis and electron microscopy. Platinum introduction into catalyst increases the metal dispersity and the catalyst stability but produces no effect on the nature of surface sites active in propylene oxidation.

    Description / Table of Contents: Abstract Рентгенографическими методами изучены два углеродных материала — сибунит и алтунит. Показано, что область когерентного рассеяния сибунита представляет собой глобулу диаметром 35 Å, в которой сохраняется слоистая структура графита с азимутальной разориентацией графитовых сеток. Алтунит имеет алмазную структуру, состоит из мелких частиц со средним размером 20 Å, лишенных микроискажений и характеризующихся узким распределением по размерам.
    Notes: Abstract Two carbon material — sibunit and altunit have been studied using X-ray phase analysis methods. Coherent scattering region of Sibunit is a globule with a diameter of 35 Å, which preserves a stratified structure of graphite with the azimutal disorientation of graphite networks. Altunit has a diamond structure and consists of small particles with the average size of 20 Å, having no microstrains and characterized by a narrow size distribution of particles.

    Notes: Conclusions 1. The reaction of H2PdCl4 with carbon supports results in the formation of chloride complexes of Pd(II) with adsorption sites located on the unoxidized sections of the surface. 2. At least three types of H2PdCl4 adsorption sites which differ in the strength of the complexes with Pd(II) formed and the reactivity to the effect of oxidants were found. It was hypothesized that the elements of the π system of the carbon support are the adsorption sites of Pd(II).
