A group of readily available zirconium catalysts incapable of ethene-co-styrene polymerization are remarkably active and selective for the production of the new polymer ethene-co-tert-butylstyrene via a single site mechanism.

Pd-Ag shell catalysts impregnated with two different ionic liquids show considerable improvements both in ethylene selectivity and reduced ethane formation in the selective hydrogenation of acetylene under tail-end conditions.

A series of Fe3O4 supported on mesoporous FDU-12 silica systems were prepared by the hydrothermal conditions. The surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like FTIR, XRD, N2 adsorption–desorption and TEM. XRD and adsorption–desorption analysis shows that the mesostructure of FDU silica remains intact after Fe3O4 modifications, wh...

Deciphering the influence of nanocatalyst morphology on their catalytic activity in oxygen evolution reaction (OER), limiting water splitting process, is essential to develop highly active precious metal-free catalysts, yet poorly understood. The intrinsic OER Co3O4 nanocubes and spheroids probed at single particle level unravel correlation between exposed facets, (001) vs. (111), activity. Sin...

Deoxyribozymes are emerging as modification-specific endonucleases for the analysis of epigenetic RNA modifications. Here, we report RNA-cleaving deoxyribozymes that differentially respond to presence natural methylated cytidines, 3-methylcytidine (m3C), N4-methylcytidine (m4C), and 5-methylcytidine (m5C), respectively. Using in vitro selection, found several DNA catalysts, which selectively ac...

the data on the effect of ethylene concentration on polymerization rate for several modifications of modern highly active titanium–magnesium catalysts ticl4/mgcl2 are presented. these catalysts differ in titanium content and conditions of support preparation, activities, and the shape of kinetic curves. it is found that the observed order of polymerization rate with respect to ethylene in the r...

A quantitative and highly selective hydrogenolysis of glycerol to 1,2-propanediol was achieved under mild conditions over bifunctional Ru/WO x catalysts.

Surface modification using Cu significantly improves the performance of Ru/MWCNT catalysts for selective production 1,2-PD up to (93.4%) from glycerol hydrogenolysis.

A combination of characterization techniques has been employed to obtain a full description of the structure and chemical state of a series of Co-W/SiO2 catalysts used for the production of single-walled carbon nanotubes (SWNT) by CO disproportionation at 750-950 °C. The state of Co and W on a series of silica-supported catalysts has been investigated using extended X-ray absorption fine struct...

The selective oxidation of n-butane to maleic anhydride over V-P-O mixed oxides was studied under oxygen deficient conditions. The mixed oxides were prepared with P/V atomic ratios ranging from 0.7 to 1.0. Catalysts with P/V (1.0 did not show any selectivity to maleic anhydride formation, regardless of whether or not (VO)2P207 was present. For catalysts with P/V = 1.0, containing by &e actual s...
