Production and applications of N-doped carbons from bioresources: A review

Construction of intimate Lewis acid and basic sites on an Al2O3–NC composite catalyst with enhanced performance in transfer hydrogenation of cinnamaldehyde

“…6d), the peaks at binding energies of 398.1, 399.5, and 400.6 eV are attributable to the C-N bonds in the pyridinic-N (CN-C), pyrrolic-N (H-N-(C) 2 ), and graphitic-N (N-(C) 3 ) groups, respectively. [46][47][48] Increasing the concentration of Al 2 O 3 led to decreased amounts of nitrogen functional groups.…”

Electron-induced hydroamination of ethane as compared to ethene: implications for the reaction mechanism

“…14,15 Their properties can be tuned and enhanced by incorporation of heteroatoms. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] Nitrogen-doping, for instance, increases the binding strength towards diverse molecules such as contaminants, 1 CO 2 , 2,3 or H 2 O. 15 It also changes the electrical conductivity of a carbonaceous material 10,13 or optical properties like the fluorescence efficiency.…”

Controlling N-Doping Nature at Carbon Aerogels from Biomass for Enhanced Oxygen Reduction in Seawater Batteries

“…Previously, we had successfully prepared carbon aerogels using coir fibers (CFs), an abundantly available agricultural waste rich in cellulose, as carbon precursors by direct pyrolysis of cellulose aerogel derived from the material. , To enrich cellulose aerogel with nitrogen as a source for N doping, an aqueous ammonia–urea system was used as the solvent for cellulose during the sol–gel process. This way, N-doped carbon aerogel could be obtained in situ during pyrolysis which is more straightforward and has greater potential to get high N content and stable product . The N-doped carbon aerogel exhibited an excellent electrocatalytic activity toward ORR in alkaline media following a two-electron-transfer mechanism .…”

“…During the carbonization process using slow pyrolysis of N-containing cellulose aerogel, temperature is a critical factor influencing the N content and the nature of N doping in carbon materials . For example, the N-content of the residue carbonaceous materials decreases with increasing temperatures, and pyridinic N and pyrrolic N are cracked to produce HCN and NH 3 at high temperatures. − In general, the pyrolysis process of cellulosic materials involves consecutive steps including dehydration (<200 °C), volatilization (200–500 °C), and carbonization (>500 °C) by depolymerization of hemicellulose, cellulose, and lignin.…”
