Catalysis chemistry

Moreover, the molecular catalysts have provided systematic opportunities to study the mechanisms of the initiation, propagation, and termination steps of coordination polymerization and the mechanisms of stereospecific polymerization. This has significantly contributed to advances in the rational design of catalysts for the controlled (co)polymerization of olefinic monomers. Altogether, the development of high performance molecular catalysts has made a dramatic impact on polymer synthesis and catalysis chemistry. There is thus great interest in the development of new molecular catalysts for olefin polymerization with a view to achieving unique catalysis and distinctive polymer synthesis.

Polymers as solids are ubiquitous in our modern society. They are some of the most common synthetic materials. Biologically derived macromolecules are also abundant. Whether it is a piece of wood, a natural fiber, or a lobster shell, nature uses solid organic macromolecular materials as key architectural material. This abundance of examples of synthetic and natural solid polymeric materials is mirrored in the prevalence with which insoluble cross-linked polymer supports are used in synthesis and catalysis [23-25]. However, while solid-phase synthesis and related catalysis chemistry most commonly employ cross-linked supports that resemble those originally used by Merrifield [26], the polymers found in nature are neither always insoluble nor always cross-linked. Indeed, soluble polymers are as common materials as their insoluble cross-linked analogs. Moreover, nature quite commonly uses soluble polymers as reagents and catalysts. Thus, it is a bit surprising that synthetic soluble polymers are so little used in chemistry as supports for reagents, substrates, and catalysts.

The focus of our work in catalysis chemistry is on homogeneous catalysis. 

The idea of using polymers as supports for catalysis chemistry is not new. Prior work with heterogeneous polymer bound transition metal catalysts extends back to the 1960s.(/-i) At that time there was considerable industrial interest in insoluble polymer supports. That interest continued through the 1970s but dwindled because homogeneous and heterogeneized catalysts were not always as comparable to one another as anticipated and because catalysts could not always be recovered and reused with the expected simplicity. Since that time there has been a rejuvenation of...

Since most of researchers in the field of photocatalysis came from different fields of chemistry, catalysis chemistry, electrochemistry, materials chemistry, photochemistry, etc., there seemed no common concepts shared by them. It is necessary to understand photocatalysis... 

Although iron has been known to man prior to 3000 BC, its use in chemistry had to wait until the twentieth century. Most of its early applications involved catalysis chemistry, primarily in the petrochemical industry. In 1983, we reported the preparation of an extremely reactive iron powder using the Rieke method [1-3].

In 1918, together with Lev Yakovlevich Karpov (1879-1921), Bakh had founded the Central Chemical Laboratory of the Supreme Council of the National Economy in Moscow. He became the first Director of this laboratory and, after Karpov s untimely death in 1921, it was renamed the L. Ya. Karpov Physicochemical Institute. For many years, this was the largest (and only) center for physical chemistry in the USSR. Despite the chaotic circumstances of its birth, it soon developed into one of the world s leading scientific centers, making important contributions to various fields of physical chemistry (electrochemistry and corrosion, theory of catalysis, chemistry of polymers, etc.). Famous scientists who worked in the Institute included A. N. Frumkin, Ya. K. Syrkin, N. M. Zhavoronkov, V. A. Kargin, I. V. Petryanov-Sokolov, S. S. Medvedev, K. A. Kocheshkov, Ya. M. Kolotyrkin, Kh.
