In this work, we developed a simple strategy to synthesize a carbon material with high nitrogen and rich carbon defects. Our approach polymerized diaminopyridine (DAP) and ammonium persulfate (APS). Following a range of different temperature pyrolysis approaches, the resulting rough surface was shown to exhibit edge defects due to N-doping on graphite carbon. A series of catalysts were evaluated using a variety of characterization techniques and tested for catalytic performance. The catalytic performance of the N-doped carbon material enhanced alongside an increment in carbon defects. The NC-800 catalyst exhibited outstanding catalytic activity and stability in acetylene hydrochlorination (C2H2 GHSV = 30 h-1, at 220 °C, the acetylene conversion rate was 98%), with its stability reaching up to 450 h. Due to NC-800 having a nitrogen content of up to 13.46%, it had the largest sp. surface area and a high defect amount, as well as strong C2H2 and HCl adsorption. NC-800 has excellent catalytic activity and stability to reflect its unlimited potential as a carbon material.

Mukherjee, Debojyoti; Manna, Rabindra Nath; Saha, Paramita; Mandal, Ujjwal; Mitra, Mainak published their research in Journal of Molecular Structure in 2021. The article was titled 《Electronic and molecular characterization of an air-stable Cr(II) complex containing azo-anion-radicals》.Recommanded Product: 141-86-6 The article contains the following contents:

A new mononuclear homoleptic chromium complex has been synthesized by reaction of one equivalent of Cr(CO)6 with two equivalent of the azoarom. pincer ligand namely 2,6-bis[(4-methylphenyl)azo]pyridine [LMe] in n-octane under reflux condition. The complex has been fully characterized by ESI-MS, 1H-NMR, FT-IR and UV/Vis spectroscopy. The X-ray structure of the complex reveals that the Cr-metal is coordinated to the central pyridine N-atom and two azo N-atoms of each tridentate pincer ligand in an octahedral environment. The 1H-NMR spectrum of the complex is indicative of diamagnetic ground state. The elongation of N-N bond lengths [d(N-N)av = 1.3275 Å] in the complex is consistent with the presence of azo-anion-radical character in the ligand. Since 2,6-bis(phenylazo)pyridine and its 4-Me-derivative are redox non-innocence in nature and therefore can coordinate to the chromium metal center as neutral (L0) or as mono-anionic mono-radical (L·)1- or as di-anionic di-radical (L··)2- or even as tri-anionic mono-radical (L·)3- resulting an ambiguity on the true oxidation state of the metal center. Thus the present work nicely elaborates the importance of suitably designed bis-azopyridine containing pincer ligand in accessing an air-stable Cr(II) complex starting with low-valent metal carbonyl precursor via electron transfer from the metal center to the highly π-acidic ligand leading to stable azo-anion-radicals. The stability of azo-anion-radical bound Cr(II) complex has been investigated by DFT calculations The experimental process involved the reaction of 2,6-Diaminopyridine(cas: 141-86-6Recommanded Product: 141-86-6)

Condensation reaction between isatin drug and 2,6-diaminopyridine in a 1:1 M ratio, has been applied to prepare a tridentate Schiff base ligand (L). A series of metal complexes Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) have been synthesized. Prepared compounds were characterized by elemental analyses, IR, 1H NMR, UV-visible, solid reflectance, molar conductivity, mass spectroscopy, x-ray diffraction, scanning electron microscope, TGA and DTG. From the anal. data, (metal:ligand) ratio was 1:1 with tetrahedral geometry except for Cr(III), Fe(III), Cd(II) and Cu(II) complexes which have an octahedral geometry. All complexes are electrolytes except Fe(III) and Cd(II) complexes are nonelectrolytes. The IR spectra suggested that the ligand is coordinated to the metal ions in a neutral tridentate manner. 1H NMR spectra confirm the participation of the amino group in coordination. In vitro antimicrobial activities for (L) and its complexes were performed. Fe(III), Cu(II) and Cd(II) complexes showed the highest antibacterial activity against S. aureus (G+ bacteria). While, Co(II) and Cd(II) complexes were the most active complexes against B. subtilis. Cd(II) and Ni(II) complexes also recorded the highest activity against G-Salmonella species and E. coli, resp. The results presented the equity of Ni(II) and Zn(II) antifungal activity against C. albicans. The cytotoxicity of the prepared compounds was experienced against breast cancer (MCF-7 cells viability). The results revealed that Mn(II) complex have the lowest IC50 value which indicates the highest activity rather than the other compounds To gain insight of the binding mode, the ligand (L) was docked with the active site receptors of (PDB code 3HB5, 6CGD, and 3LD6).

Developing transition-metal excluding iron and cobalt-nitrogen-carbon (M-N-C) electrocatalysts for the oxygen reduction reaction (ORR) is critical to substantially promote the development of precious-metal-free metal-air batteries and fuel cells. In the work, Mn-N-C nanoparticles with atomically dispersed MnNx moieties were synthesized by pyrolyzing Mn-ion-dual-pyridine coordinated complex, which was obtained via a simple condensation reaction between 2,6-diamino-pyridine and 2,6-diacetyl-pyridine with MnCl2 as the Mn source. The precursor features with a characteristic structure of dual-pyridine ligand, which possesses a strong coordinating capability for Mn2+, facilitating the formation of highly dispersed nitrogen-coordinated Mn sites (MnNx). Attributed to the highly active at. MnNx sites, hierarchical pore structure, and high surface area of the Mn-N-C derived from the new precursor, it exhibits outstanding ORR performance in 0.1 M KOH with an almost direct four-electron reaction path and high selectivity of O2 into H2O (low H2O2 production < 3.5%). The half-wave potential of Mn-N-C is 0.88 V vs. RHE, which is 20 mV higher than that of com. Pt/C catalyst and reaches to the level of Fe-N-C catalyst obtained by the same method. Meanwhile, the feasibility of Mn-N-C for practical application is validated by its higher-performance power output in Zn-air battery with a maximum power d. of 132 mW cm-2 compared to that of Pt/C (121 mW cm-2) using the same catalyst loading of 1.0 mg cm-2. This work develops a convenient route to develop non-Fe or Co-N-C electrocatalyst for the ORR. Highly efficient Mn-N-C electrocatalysts with atomically dispersed MnNx moieties were developed for oxygen reduction reaction in Zn-Air batteries.

《Zinc-Mediated Template Synthesis of Fe-N-C Electrocatalysts with Densely Accessible Fe-Nx Active Sites for Efficient Oxygen Reduction》 was written by Chen, Guangbo; Liu, Pan; Liao, Zhongquan; Sun, Fanfei; He, Yanghua; Zhong, Haixia; Zhang, Tao; Zschech, Ehrenfried; Chen, Mingwei; Wu, Gang; Zhang, Jian; Feng, Xinliang. SDS of cas: 141-86-6 And the article was included in Advanced Materials (Weinheim, Germany) in 2020. The article conveys some information:

Owing to their earth abundance, high atom use, and excellent activity, single Fe atoms dispersed on N-doped carbons (Fe-N-C) have emerged as appealing alternatives to noble-metal Pt for catalyzing the O reduction reaction (ORR). However, the ORR activity of current Fe-N-C is seriously limited by the low d. and inferior exposure of active Fe-Nx species. Here, a novel Zn-mediated template synthesis strategy is demonstrated for constructing densely exposed Fe-Nx moieties on hierarchically porous C (SA-Fe-NHPC). During the thermal treatment of 2,6-diaminopyridine/ZnFe/SiO2 complex, the Zn prevents the formation of Fe carbide nanoparticles and the SiO2 template promotes the generation of hierarchically pores for substantially improving the accessibility of Fe-Nx moieties after subsequent leaching. As a result, the SA-Fe-NHPC electrocatalysts exhibit an unprecedentedly high ORR activity with a half-wave potential (E1/2) of 0.93 V in a 0.1 M KOH aqueous solution, which outperforms those for Pt/C catalyst and state-of-the-art noble metal-free electrocatalysts. As the air electrode in Zn-air batteries, the SA-Fe-NHPC demonstrates a large peak power d. of 266.4 mW cm-2 and superior long-term stability. Therefore, the developed Zn-mediated template synthesis strategy for boosting the d. and accessibility of Fe-Nx species paves a new avenue toward high-performance ORR electrocatalysts. In the experiment, the researchers used 2,6-Diaminopyridine(cas: 141-86-6SDS of cas: 141-86-6)
