The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about The Active Center of Co-N-C Electrocatalysts for the Selective Reduction of CO2 to CO Using a Nafion-H Electrolyte in the Gas Phase, the main research direction is cobalt complex electroreduction catalyst carbon dioxide monoxide.Computed Properties of C12H12N2.
To contribute a solution for the global warming problem, the selective electrochem. reduction of CO2 to CO was studied in the gas phase using a [CO2(g), Co-N-C cathode | Nafion-H | Pt/C anode, H2/water] system without using carbonate solutions The Co-N-C electrocatalysts were synthesized by partial pyrolysis of precursors in inert gas, which were prepared from various N-bidentate ligands, Co(NO3)2, and Ketjenblack (KB). The most active electrocatalyst was Co-(4,4′-dimethyl-2,2′-bipyridine)/KB pyrolyzed at 673 K, denoted Co-4,4′-dmbpy/KB(673K). A high performance of CO formation (331 μmol h-1 cm-2, 217 TOF h-1) at 0.020 A cm-2 with 78% current efficiency was obtained at -0.75 V (SHE) and 273 K under strong acidic conditions of Nafion-H. Characterization studies using extended X-ray absorption fine structure (EXAFS), XPS, transmission electron microscopy-energy-dispersive X-ray (TEM-EDX), X-ray diffraction (XRD), and temperature-programmed desorption with mass spectrometry (TPD-MS) indicated the active site as Co coordinated with four N atoms bonding the surface of KB, abbreviated Co-N4-Cx structure. A model of the reduction mechanism of CO2 on the active site was proposed.
There is still a lot of research devoted to this compound(SMILES：CC1=CN=C(C=C1)C1=NC=C(C)C=C1)Computed Properties of C12H12N2, and with the development of science, more effects of this compound(1762-34-1) can be discovered.
