Bimetallic Cobalt Based Catalysts

Catalysis Reviews, 2010
Highly dispersed, oxide- or zeolite-supported bimetallic catalysts are widely used in the catalytic industry, such as in catalytic reforming, nitrogen industry and gas-to-liquid technology. The paper highlights the nano-sized Co-based bimetallic system in terms of correlation between structure and reactivity/selectivity promoted by the second metal ...

Hydroperoxidations of Alkenes using Cobalt Picolinate Catalysts

Organic Letters, 2021
Hydroperoxides were synthesized in one step from various alkenes using Co(pic)2 as the catalyst with molecular oxygen and tetramethyldisiloxane (TMDSO). The hydration product could be obtained using a modified catalyst, Co(3-mepic)2, with molecular oxygen and phenylsilane.

Cobalt/manganese oxide catalysts

Applied Catalysis A: General, 1992
Abstract Co/MnO (1:1) catalysts, active for the carbon monoxide hydrogenation reaction, were modified with chromium promoters (2–25% by mass; relative to Co). Significant changes in hydrocarbon selectivities were observed consistent with an increase in chain propagation ( α 2 increased from 0.90 to 0.94 ). Studies on the effect of operating pressure,

Asymmetric skeletal cobalt catalyst

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1971
1. It was found that a modified skeletal Co catalyst is active in the asymmetric synthesis ofβ-hydroxybutyrate. The highest optical yield reaches 8.1% at a modification pH of 3.6. 2. The asymmetric yield depends on the temperature of leaching the starting Co-Al alloy. 3.

Characterization of cobalt Fischer-Tropsch catalysts I. Unpromoted cobalt-silica gel catalysts

Applied Catalysis A: General, 1995
Abstract The effect of preparation conditions on cobalt-silica gel catalysts has been investigated by temperature-programmed reduction, differential thermal analysis, X-ray photoelectron spectroscopy, and magnetic susceptibility measurements. The results have been correlated with the performance of the catalysts for the conversion of syngas.
