Catalytic Aerobic Oxidation of Cycloalkanes with Nanostructured Amorphous Metals and Alloys

Abstract

Under mild conditions (40 atm O(2), 28 degrees C, 10-15 h), an efficient aerobic oxidation of cycloalkanes to cycloalkanols can be achieved using nanostructured amorphous metals such as Fe and Co and an amorphous alloy like Fe(20)Ni(80) as catalysts. For example, cyclohexane is oxidized to cyclohexanol with 32-41 % conversion, while 1-adamantanol is formed from adamantane with 52-57 % conversion.

Synthesis of iron oxide nanoparticles of narrow size distribution on polysaccharide templates

“…Nanomaterials may also be used in various technological applications viz. refrigeration systems, medical imaging, drug targeting and other biological applications, and catalysis (Kesavan et al 1999). The synthesis of nanoparticles of magnetic metal and metal oxides have been reported in recent times by using different chemical methods viz.…”

Catalytic oxidation of cyclohexane to cyclohexanol and cyclohexanone over Co3O4 nanocrystals with molecular oxygen

“…The properties of these materials mainly depend on their shape, size, and structure, which are strongly determined by the synthetic processes. Nanostructured catalysts, such as Fe 2 O 3 , Co 3 O 4 , and mixed Fe-Co oxide, have been employed in the cyclohexane oxidation [13][14][15]. Unfortunately, these catalysts are unstable during the reaction.…”

“…2 Mesoporous materials may also be used in various technological applications viz refrigeration systems, medical imaging, drug targeting and other biological applications and catalysis. 3 In recent years, interest in electrochemical capacitors (ECs) has risen due to their higher power density and longer cycle life compared to secondary batteries and higher energy density that conventional electrical double-layer capacitors. [4][5][6] They play increasingly important roles in power source applications such as auxiliary power sources for mobile electronic devices, etc.…”
