- W2797188493 abstract "Here, we report cobalt nanoparticles encapsulated in nitrogen-doped carbon ([email protected]) that exhibit excellent catalytic activity and chemoselectivity for room-temperature hydrogenation of nitroarenes. [email protected] was synthesized by pyrolyzing a mixture of a cobalt salt, an inexpensive organic molecule, and carbon nitride. Using the [email protected] catalyst, a turnover frequency of ∼12.3 h−1 and selectivity for 4-aminophenol of >99.9% were achieved for hydrogenation of 4-nitrophenol at room temperature and 10 bar H2 pressure. The excellent catalytic performance can be attributed to the cooperative effect of hydrogen activation by electron-deficient Co nanoparticles and energetically preferred adsorption of the nitro group of nitroarenes to electron-rich N-doped carbon. In addition, there is electron transfer from the Co nanoparticles to N-doped carbon, which further enhances the functionality of the metal center and carbon support. The catalyst also exhibits stable recycling performance and high activity for nitroaromatics with various substituents." @default.
