Biomolecule-derived supported cobalt nanoparticles for hydrogenation of industrial olefins, natural oils and more in water

Abstract

Biomolecule modified supported cobalt nanoparticles efficiently hydrogenate diverse natural, industrial and functionalized olefins in water under mild conditions.

Ambient Hydrogenation and Deuteration of Alkenes Using a Nanostructured Ni‐Core–Shell Catalyst

“…In addition, the majority of these reactions require high pressure of hydrogen (up to 50 bar) and sometimes higher reaction temperatures (>100 °C), which requires specific equipment and additional energy. [ 11 , 17 ] In this respect, the development of more active catalysts which allow for minimal energy consumption and low pressure is highly desired, but scientifically very challenging. So far, such hydrogenations can only be achieved under mild conditions in the presence of precious metal catalysts.…”

“…[ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ] In this respect, we recently introduced nanostructured materials based on the pyrolysis of cobalt salts and biopolymers for the hydrogenation of alkenes, however these materials also showed no hydrogenation reactivity at ambient conditions. [ 11 , 17 ] In fact, to the best of our knowledge, until now 3d‐metal‐based heterogeneous catalysts for the hydrogenation of alkenes at ambient conditions (1 bar hydrogen, RT) have not been reported.…”

“…Unfortunately, both materials have certain disadvantages: While the former is highly sensitive and requires special handling, the latter is quite expensive. In addition, the majority of these reactions require high pressure of hydrogen (up to 50 bar) and sometimes higher reaction temperatures (>100 °C), which requires specific equipment and additional energy [11, 17] . In this respect, the development of more active catalysts which allow for minimal energy consumption and low pressure is highly desired, but scientifically very challenging.…”

“…Unfortunately,b oth materials have certain disadvantages:W hile the former is highly sensitive and requires special handling,t he latter is quite expensive.I n addition, the majority of these reactions require high pressure of hydrogen (up to 50 bar) and sometimes higher reaction temperatures (> 100 8 8C), which requires specific equipment and additional energy. [11,17] In this respect, the development of more active catalysts which allow for minimal energy consumption and low pressure is highly desired, but scientifically very challenging. So far, such hydrogenations can only be achieved under mild conditions in the presence of precious metal catalysts.However,atthis point it should also be noted that due to the exothermicity of hydrogenations for large scale applications low temperature reactions are not ideal because such processes would require cooling.T hus,h ydrogenations at ambient conditions specifically offer advantages for fine chemical products and organic synthesis.Apart from that, am odern state-of-the-art catalyst for olefin hydrogenation should be based on 3d-metals due to their availability and price advantages.…”

“…On the other hand, heterogeneous catalysts are generally more stable and permit easier recycling and reusability [20–28] . In this respect, we recently introduced nanostructured materials based on the pyrolysis of cobalt salts and biopolymers for the hydrogenation of alkenes, however these materials also showed no hydrogenation reactivity at ambient conditions [11, 17] . In fact, to the best of our knowledge, until now 3d‐metal‐based heterogeneous catalysts for the hydrogenation of alkenes at ambient conditions (1 bar hydrogen, RT) have not been reported.…”
