Abstract:
We report the development of MOF-derived nitrogen-doped carbon/Co3O4 nanocomposites (Co3O4@NCs) with core-shell structures as an efficient electrocatalyst for the artificial nitrogen fixation at room temperature and atmospheric pressure in 0.05 M H2SO4. It exhibits a high NH3 yield of 42.58 μg h-1 mgcat.-1 and a faradaic efficiency of 8.5% at -0.2 V versus reversible hydrogen electrode. Experimental results show that the great N2 reduction reaction performance of Co3O4@NCs originates from the synergistic effects of N-doped carbon and Co3O4 with significant oxygen vacancy. In addition, we speculate that the core-shell structure can further enhance the electrochemical activity for producing NH3.

The chemical gradient relies on differences in the abundance of a substance on the outside versus the inside of a cell and flows from areas of high to low ion concentration. In contrast, the electrical gradient revolves around an...

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

01:28Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
