A nitrogen-containing molecular sieving carbon which contains at least 0.1 weight % nitrogen bonded to constituent carbon of the activated carbon. It exhibits improved ability to remove nitrogen oxides compared with the conventional adsorption methods using commercially available activated carbons or other ...
In the graphene doped with pyrrolic N (pyrr-G-1N) model, the incorporated nitrogen is bonded to two carbon atoms to form a five-membered ring. Hydrogen atoms are introduced on the carbon near the nitrogen [40]. The graphene doped with pyridinic N (pyri-G-1N) was constructed by ...
Pyrrolic N atoms are incorporated into five-memberedheterocyclicrings and are bonded to two carbon atoms. Such nitrogen species are not very common in carbon materials because pyrrolic species have a low stability, what makes that the concentration of this functionality is low after a carbonization ...
3) double-bonded carbonic acid 碳氮双键1. This paper, according to the process of double-bonded carbonic acid reduction, the isomerism of hydrazone & alkali reduction, depicts the current polarogram research of double-bonded carbonic acid. 本文从碳氮双键的还原过程、腙的异构和希夫碱的还原三个...
Pyridinic nitrogen, that is N bonded to two C atoms in six-membered rings at the edge of the graphitic carbon layer, would provide the main initial active sites for electrochemical behaviors18,19. Scientific REPOrTS | 7:40259 | DOI: 10.1038/srep40259 4 www.nature.com/scientificreports/ ...
Nitrogen-doped porous activated carbon monoliths (NDP-ACMs) have long been the most desirable materials for supercapacitors. Unique to the conventional template based Lewis acid/base activation methods, herein, we report on a simple yet practicable novel approach to production of the three-dimensional...
(1.1 million atm) and high temperatures (2000 K), as produced using a diamond anvil cell, nitrogen polymerizes into the single-bonded cubic gauche crystal structure. This structure is similar to that of diamond, and both have extremely strong covalent bonds. N4 is nicknamed "nitrogen diamond....
Space-charge and current non-uniformities, and contact resistivity of end-bonded metal contacts to thin heavily doped semiconductor nanowires Prior work calculated the contact resistivity, rho(CN), of end-bonded metal contacts on n-type silicon NanoWires (NWs) of radius, R = 5-10 nm and dopin...
Carbon nanotube nano reactors When graphene sheets of a single layer of bonded carbon atoms are rolled up, they can form cylindrical molecules with a diameter on the order of nanometres, called carbon nanotubes. Like test tubes, high-strength and high-stability nanotubes can be used as container...
In addition, X-ray photoelectron spectroscopy (XPS) and temperature programmed desorption (TPD), discussed in Supplementary Note 2, were conducted to rule out the likelihood of pyrrolic nitrogen formation and confirm the singly N-N bonded polymeric phase. Results Raman and ATR-FTIR spectroscopy A ...
