“…Other than that, at the same deposition temperature, a-C:N has better structure as compared to the pure a-C. Small roughness indicates the lower grain boundaries, which can be related to the tendency of the particle to become more crystallite [15]. The roughness value obtained was similar to the one reported by Miyajima et al [16]. Table 1 provides the average roughness value for numerical comparison.…”

“…Aside from that, at the same deposition temperature, a-C:N has a superior structure than pure a-C. Small roughness suggests lower grain boundaries, which can be linked to the particle's proclivity to crystallise (Hagouel, 2005). The acquired roughness value was close to that reported by (Miyajima et al, 2005).…”

In the modern era, it is very crucial to utilize the sustainable energy that is abundant in nature especially the solar energy. Due to this reason the research to develop an economically solar cell has been extensively studied. Aerosol-Assisted CVD, an economically developed method to produce the carbon solar call has proven its ability in this area to produce the solar cell. Five samples of pure a-C and nitrogen doped a-C:N were produced, with deposition temperatures ranging from 400°C to 600°C. The current-voltage solar simulator characterization yielded an ohmic contact. Higher conductivity at a-C:N, x10-2 Scm-1 is attributable to a decrease in defects caused by the decrease in spin density gap with nitrogen addition. AFM measurements of structural characteristics at high temperatures reveal an even smoother image as the intense carbon ion bombardment at the thin film's surface increases.

“…Thin film carbon nitride in its many forms has been well characterized. [32][33][34][35] Carbon nitride in its planar phase has been chemically synthesized as powder, in gram quantities, relatively recently. 36 This phase is analogous to graphite, but has both graphitelike ͑qua-ternary͒ and pyridine-like nitrogen atoms, while each carbon atom is bonded to three nitrogen atoms ͑Fig.…”

Electrochemical oxygen reduction via nonprecious, Fe/N/C catalysts has potential to reduce the cost and increase acceptance of hydrogen-powered polymer electrolyte membrane fuel cells. However, because these materials are a complex mixture of carbon, nitrogen, and iron, the nature of the active site is still much debated. By using carbon nitride as an ideal, nitrogen-rich, iron-free catalyst we shed light on the role of carbon-nitrogen bonding in electrochemical oxygen reduction. Carbon nitride was synthesized on a carbon black support via a simple solvothermal process. The resulting material was pyrolyzed and characterized via a variety of techniques. Electrochemical testing revealed that carbon nitride pyrolyzed at 1000°C displayed the best oxygen reduction activity, with an onset potential of 0.90 V and a low selectivity to H 2 O 2 formation, indicating a 4-electron oxygen reduction pathway. Due to small amounts of Fe contamination in this series of samples, an Fe-free sample was prepared without the carbon black support, resulting in similar electrochemical properties. The enhanced activity is tentatively attributed to enriched quaternary nitrogen in the material at this temperature, as suggested by X-ray photoelectron spectroscopy.
