Abstract

The chicken feather-derived N-doped porous carbons exhibit excellent electrochemical performance and high CO2 uptake.

Facile One‐Pot Synthesis of Activated Porous Biocarbons with a High Nitrogen Content for CO2 Capture

“…The non‐activated nitrogen‐containing sample NEPB‐3U shows the highest value for carbon but the lowest value for oxygen content (Table ) indicating less oxidation of carbon network in the absence of the activating agent. On the other hand, NEPB‐3UK shows the highest value for oxygen content in the structure, which suggests the successful oxidation and activation of the carbon network can be achieved using by employing KOH as an activating agent . This oxygen is not associated with nitrogen as oxides, which is indicated by the absence of any characteristic peak in the high‐resolution N1s spectra for this sample (Figure c).…”

“…On the other hand, NEPB-3UK shows the highest value for oxygen content in the structure, which suggests the successful oxidation and activation of the carbon network can be achieved using by employing KOH as an activating agent. [38] This oxygen is not associated with nitrogen as oxides, which is indicated by the absence of any characteristic peak in the high-resolution N1s spectra for this sample (Figure 5c). It also indicates that oxygen is more reactive as compared to nitrogen in forming the functional groups on the surface of activated biocarbon.…”

Catalytic Activity of Bimetallic (Ruthenium/Palladium) Nano‐alloy Decorated Porous Carbons Toward Reduction of Toxic Compounds

“…[11] Hence, an abundant content (polypeptides, sulfur and nitrogen moiety) in the CFWs make it ab eneficial low-cost raw materialf or the fabrication of PCs. Todays, bio-waste carbons have been used severale lectrocatalytic [12][13][14][15] and catalytic [16][17][18][19] applications, because of their large surface area, easy accessibility,e xcellent recoverability,r eusability,a nd less toxicity.…”

Template-free synthesis of nitrogen doped carbon materials from an organic ionic dye (murexide) for supercapacitor application

“…44 The Bode plots display the dependence of the phase angle on the shows that the NCM (MDE) -800 electrode has the highest phase angle, almost 86 at 10 mHz AC frequency, close to the ideal capacitor behaviour. Since high power demanding applications require the charging and discharging of electrode material at high current densities, high capacitance retention at high scan rates or at high current densities is key for practical applications.…”

“…3 plane of hexagonal graphitic carbon. 43,44 The presence of the broad (002) peak together with the sharp peaks (100/101) and (103) in the XRD patterns of these NCMs indicates the coexistence of amorphous and crystalline phases. The former phase is related to the disordered structure, manifesting heteroatom (nitrogen) doping, while the latter phase conrms the level of ordered structure maintained by these NCMs even at high nitrogen content.…”
