Lithium and Sodium Storage on Graphitic Carbon Nitride [PDF]

The Journal of Physical Chemistry C, 2015
We present results from density functional theory calculations of the lithium adsorption onto 2D graphitic carbon nitride membranes, C3N4 and C6N8 and bulk C3N4. We find that lithium adsorbs preferentially over the triangular pores with a high adsorption energy. We also find that lithium adsorption severely distorts the membrane and bulk material.

A Comprehensive Review of Graphitic Carbon Nitride (g-C3N4)–Metal Oxide-Based Nanocomposites: Potential for Photocatalysis and Sensing

Nanomaterials, 2022
g-C3N4 has drawn lots of attention due to its photocatalytic activity, low-cost and facile synthesis, and interesting layered structure. However, to improve some of the properties of g-C3N4, such as photochemical stability, electrical band structure, and

Preparation of carbon nitride films from g-C3N4 by ion-beam-assisted deposition

Mechanical Engineering Journal, 2019
Carbon nitride has noteworthy properties including high hardness levels. If the c-C3N4 or β-C3N4 structure can be synthesized, then hardness levels higher than that of diamond can be obtained.

Rational design of carbon nitride photocatalysts by identification of cyanamide defects as catalytically relevant sites

Nature Communications, 2016
Graphitic carbon nitride is a promising hydrogen evolution photocatalyst, although there is limited understanding of its mechanistic operation. Here, the authors employ molecular heptazine-based model catalysts to identify catalytically relevant defects ...
