From Molecular Building Blocks to Condensed Carbon Nitride Networks: Structure and Reactivity [PDF]

, 2006
The scope of this thesis was defined by three major issues, which have been arising from the requirement to further extend and to deepen research on carbon nitride chemistry from a materials chemistry point of view. Access to highly condensed CNx species

Extent of carbon nitride photocharging controls energetics of hydrogen transfer in photochemical cascade processes

Nature Communications, 2023
Graphitic carbon nitride is widely studied in organic photoredox catalysis. Reductive quenching of carbon nitride excited state is postulated in many photocatalytic transformations.

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.

Salt-air template synthesis of Na and O doped porous graphitic carbon nitride nanorods with exceptional photocatalytic H2 evolution activity

, 2021
Photocatalyst fabrication process plays the central role in photocatalytic hydrogen (H2) evolution reaction. Herein, we synthesize Na+ functionalized porous graphitic carbon nitride nanorods (Na-CNNR) via a facile one-pot calcination method.

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 ...

Bamboo-charcoal-loaded graphitic carbon nitride for photocatalytic hydrogen evolution

, 2022
Crystalline graphitic carbon nitride is an excellent photocatalyst for hydrogen production due to its non-toxicity, stability, elemental abundance, and visible-light response. Herein, we present a new type of composite photocatalysts, eco-friendly bamboo-

First-principles prediction of metal-free magnetism and intrinsic half-metallicity in graphitic carbon nitride [PDF]

, 2012
Transition metal-free magnetism and half-metallicity recently has been the subject of intense research activity due to its potential in spintronics application. Here we, for the first time, demonstrate via density functional theory that the most recently
