Ultrafast plasma immersion strategy for rational modulation of oxygen-containing and amino groups in graphitic carbon nitride

One-Dimensional Multichannel g-C3N4.7 Nanostructure Realizing an Efficient Photocatalytic Hydrogen Evolution Reaction and Its Theoretical Investigations

“…However, the IR peak at ∼813 cm –1 resembles a unique C–N heterocyclic framework, whereas the peaks in the region of 1200–1700 cm –1 corresponds to the stretching modes of C–N and CN units present in the s -triazine motifs. The broad peak at 3000–3600 cm –1 can be corroborated to the uncondensed terminal N–H stretching of nonpolymerized −NH x groups that adhered to the surface of the present graphitic MDY structure (more characterization on latter sections) which play a pivotal role in enhancing the electron density into the triazine structure. ,, …”

“…The broad peak at 3000− 3600 cm −1 can be corroborated to the uncondensed terminal N−H stretching of nonpolymerized −NH x groups that adhered to the surface of the present graphitic MDY structure (more characterization on latter sections) which play a pivotal role in enhancing the electron density into the triazine structure. 19,33,35 The transmission electron microscopy (TEM) images illustrate a 1-D morphology of the MDY sample with a wellordered multichannel tubular mesoporous structure of uniform pore size where the pores are surrounded by thin CN walls, as visualized in Figures 1c and S2a−c. Under a high-resolution transmission electron microscope (HRTEM, Figure 1d), the pore wall images are observed as bright contrast strips and the empty channels as dark contrast cores.…”

Utilizing E-Waste for Construction of Magnetic and Core–Shell Z-Scheme Photocatalysts: An Effective Approach to E-Waste Recycling

“…As can be seen from C 1s spectra (Figure 2c), the peaks at 288.2 and 284.9 eV for g-C 3 N 4 corresponded to the sp 2 -bonded carbon (N−CN) and graphitic carbon, respectively. 28 The C 1s peak positions of the Nb−Pb−BTO/Ni−Pd−Ag−Sn@CN10 composite photocatalyst were nearly unchanged. However, the intensity of the peak at 284.9 eV was enhanced, which could be attributed to the carbonization of g-C 3 N 4 during ball-milling.…”

Graphitic carbon nitride nanosheets with low ON1-doping content as efficient photocatalysts for organic pollutant degradation

“…It is worth noting that the O N1 -doping model was an oxygen-containing group regulation. 16,45 As shown in Fig. 5, the O N1 -doping models of the g-C 3 N 4 nanosheets with one, two and three oxygen atoms in the 2 × 2 heptazine units were constructed by VASP, respectively.…”
