Pyridine-N-oxides are often used as reactive precursors in the syntheses of substituted pyridines. Isolation and subsequent reduction of the associated pyridine-N-oxide intermediates can be challenging. We have discovered that tetrahydroxydiboron functions as a mild, versatile, and remarkably selective ...
N-GQDs hybrid played a good role in ORR, especially that made by using pyridine as a nitrogen precursor. N-GQDs have their uses in electro-catalytic activity [215]. B- and N-doped GQDs possessed high electrical conductivity and high surface area, which made the resulting material an oxygen...
2. Brucine N -oxide was also reduced by rabbit liver cytosol and blood in the presence of both a reduced pyridine nucleotide and FAD under anaerobic conditions. The N -oxide reductase activities were inhibited by carbon monoxide and air. However, these activities were not abolished when liver ...
reported that Sn-N-C catalyst surpassed Fe-N-C in terms of hydrogen-air fuel cells power density, showing high selectivity to the four-electron reduction pathway and Fenton-inactive character of Sn. Sn(IV)Nx single-metal site with moderate oxygen adsorption and low pyridine N coordination ...

The direct reduction of NO by pyridine molecule should overcome lower energy barrier, which could occur at wider temperature range. Pyrrole is less thermostable than pyridine; the energy barriers of pyrrole cracking and direct reduction of NO stay at same level. Therefore, the reburning efficiency ...
corresponding amine (16–20). Furthermore, various dinitrobenzenes and nitroanilines can be fully converted into benzenediamine products (16,17,24–30, and31). More importantly, BaNTR1 can also accept various bulky nitroarenes and nitro-heteroarenes, including the electron-deficient pyridine and ...
As an example, CNx materials can be synthesized using chemical vapor deposition of a C and N source (such as CH3CN) over a metal-doped support (such as MgO, SiO2, or Al2O3) followed by an acid-washing step to remove the exposed metal and the oxide support [16], [17]. Thus, ...
4b) [43]. Compared to N-AC, Fe@N-CNTs, and Co@N-CNTs, bimetallic FeCo@N-CNTs were mainly composed of pyridine-N (54.0 %) and graphitic-N (28.8 %, Fig. S6), which feature with six-membered ring structures and higher thermal stability during carbonisation. Introducing metals ...
