X-ray diffractograms for titanium dioxide, graphitic carbon nitride, and their composites

X-ray diffractometry (XRD) spectra for titanium dioxide (TiO2), graphitic carbon nitride (g-C3N4), and their composites annealed at 200 and 300 oC. Bulk graphitic carbon nitride was prepared by polymerizing pure urea at 600 oC.

Synthesis, Structure and Electronic Properties of Graphitic Carbon Nitride Films [PDF]

, 2018
Dark-colored shiny flakes of graphitic carbon nitride materials produced by reacting dicyandiamide C2N4H4 in a KBr/LiBr molten salt medium were determined to have a C/N ratio near 1.2:1. The compounds also contained 2.3-2.5 wt % H incorporated within N-H

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials

Advanced Materials Interfaces, EarlyView.
Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

Fabrication of Ag3PO4/g-C3N4 heterojunction photocatalyst via in-situ growth and its photocatalytic performance.

PLoS ONE
Current methods for fabricating heterojunction photocatalysts often involve complex processes and weak interfacial bonding. To address the limitations of complex processes and weak interfacial bonding in existing heterojunction photocatalyst fabrication,

Oxo dicopper anchored on carbon nitride for selective oxidation of methane

Nature Communications, 2022
Selective conversion of methane into value-added chemicals is a promising approach for utilization of hydrocarbon sources. Here the authors develop dimeric copper centers supported on graphitic carbon nitride (denoted as Cu2@C3N4) with >10% conversion ...

Afterglow Electrochemiluminescence from Nitrogen-Deficient Graphitic Carbon Nitride

, 2023
Almost all current electrochemiluminescent reagents require real-time electrochemical stimulation to emit light. Here, we report a novel electrochemiluminescent reagent, nitrogen-deficient graphitic carbon nitride (CNx), that can emit afterglow ...

Stabilizing Electrochemical Interfaces With Multifunctional Cobalt Nitride Layers

Advanced Materials Interfaces, EarlyView.
Cobalt nitrides emerged recently as an interesting class of earth‐abundant oxygen evolution catalysts. Herein, plasma‐enhanced atomic layer deposition is used to synthesize multifunctional cobalt nitride layers that simultaneously protect and catalytically activate photoelectrode surfaces.
