“…Other electrophilic species such as O 2 and Fe 3+ were also possible to be detected using NCNTs-based electrochemical sensors [704]. Electrocatalytic oxidation of NO is enhanced by N doping of carbon lattice, giving rise to a possibility of easy detection and removal of NO by NCNSs electrodes [198,227,228,702].…”

Recent Progress on the Growth Mechanism of Carbon Nanotubes: A Review

2011

View full text Add to dashboard Cite

Tremendous progress has been achieved during the past 20 years on not only improving the yields of carbon nanotubes and move progressively towards their mass production, but also on gaining a profound fundamental understanding of the nucleation and the growth processes. Parameters that influence the yield but also the quality (e.g., microstructure, homogeneity within a batch) are better understood. The influence of the carbon precursor, the reaction conditions, the presence of a catalyst, the chemical and physical status of the latter, and other factors have been extensively studied. The purpose of the present Review is not to list all the experiments reported in the literature, but rather to identify trends and provide a comprehensive summary on the role of selected parameters. The role of the catalyst occupies a central place in this Review as a careful control of the metal particle size, particle dispersion on the support, the metastable phase formed under reaction conditions, its possible reconstruction, and faceting strongly influence the diameter of the carbon nanotubes, their structure (number of walls, graphene sheet orientation, chirality), their alignment, and the yield. The identified trends will be compared with recent observations on the growth of graphene. Recent results on metal-free catalysts will be analyzed from a different perspective.

“…[12] The Ramans pectrum of the BNC ( Figure S1) shows the two characteristic bands of graphite at approximately 1350 (Dband) and 1600 cm À1 (G-band), which indicates thee xistence of the sp 2 -hybridized carbon network of graphite. [13] In addition, it is well known that the relative intensities of D-a nd Gbands (I D /I G )a re inverselyp roportionalt ot he crystallite size of graphite. The BNC had an I D /I G ratio of 0.84, which indicates the good graphitized structure of the BNC.…”

AB ,N-codoped carbon material( BNC) was prepared by as imple method and employed as am etal-free catalyst in the transfer hydrogenation of nitroarenes in aqueous solution. In the preparation of the BNC, boric acid not only functions as the template during the carbonizations tep but also serves as the source for the Bd opant in the final BNC product. Nitrilotriacetica cid (NTA) serves as the carbon and nitrogen source for the system. Characterization of the intermediate materials prepared during the synthesis indicate that the boron nitride (BN) contento ft he BNC increases at higher calcination temperatures. Thef inal B,N-codoped carbon material showede xcellent catalytic activity and high selectivity in the transfer hydrogenations of nitroarenes under moderate reaction conditions (52.1-100 %y ield). Results of control experiments suggest that the BN domain of the BNC is ak ey factor to its catalytic activity.D ensity functional theory calculations show that boron atoms facilitate the adsorption and activation of the nitrobenzene and hydrazine molecules. Nitrogen atoms store the active hydrogen atoms that are generated during the catalytic process and transfer them to the nitroarene. This synergistic effect between the Ba nd Nd opants in the BN domain of the BNC was used to successfully promotet he catalytic transfer hydrogenation of nitroarenes.
