Two dimensional N-doped ZnO-graphitic carbon nitride nanosheets heterojunctions with enhanced photocatalytic hydrogen evolution

2D‐2D Nanocomposite of MoS2‐Graphitic Carbon Nitride as Multifunctional Catalyst for Sustainable Synthesis of C3‐Functionalized Indoles

“…It can be seen that GCN exhibits two distinct diffraction peaks at 2 θ values of 13.0° and 27.5°, which are assigned to the (1 0 0) and (0 0 2) reflection planes, respectively. The strong diffraction peak at 27.5° corresponds to an interlayer d‐spacing of 0.336 nm of GCN and represents the stacking of the conjugated double bonds, whereas the weak diffraction peak at 13.0° corresponds to an interplanar separation of 0.672 nm . These two diffraction peaks are in good agreement with the reported literature (JCPDS 87–526) for GCN .…”

These two diffraction peaks are in good agreement with the reported literature (JCPDS 87–526) for GCN . The XRD pattern of MoS 2 has three discernible diffraction peaks at 2 θ values of 14.2°, 32.5°, and 57.0°, which could be indexed to the (0 0 2), (1 0 0), and (1 1 0) reflection planes of crystalline MoS 2 as previously reported (JCPDS no.…”

“…From the results presented in Figure b, it can be seen that bare GCN exhibits a series of peaks related to its polymeric structure. The broad absorption band at 3500–3000 cm −1 originates from the stretching vibration of N−H bonds, associated with uncondensed amino groups, whereas a series of peaks at 1600–1200 cm −1 could be assigned to the stretching vibrations of C−N heterocycles . The above distinct modes of vibrations confirm the formation of C−N−C bonds in the graphitic material.…”

Application of Z–Scheme CdSWO3 Nanocomposite for Photodegradation of Ethylparaben under Irradiation with Visible Light: A Combined Experimental and Theoretical Study

“…CdS WO 3 3:7 possess a direct band gap of 1.83 eV and an indirect band gap of 2.34 eV. This phenomenon was consistent with 2D nanocomposite in which they both exhibit combinations of both band gap energies and this was attributed to the sheet–like and sphere–like structures of WO 3 and CdS, respectively.…”

Growth of ZnO Nanorods on Graphitic Carbon Nitride gCN Sheets for the Preparation of Photocatalysts with High Visible‐Light Activity

“…Moreover, in most reports focused on the preparation of ZnO/gCN composites, the influence of ZnO particles size and morphology on the photocatalytic activity has been poorly investigated likely due to the poor control on these parameters when generating ZnO at high temperature. Only a very recent example reports the generation of N‐doped ZnO nanosheets at the surface of gCN sheets for the photocatalytic hydrogen production …”
