Insights on advanced g‐C3N4 in energy storage: Applications, challenges, and future

“…The discovery of g‐C 3 N 4 as a metal‐free conjugated semiconductor photocatalyst for H 2 evolution was first reported by Wang et al in 2009, 88 which may also lead to research and exploration of the potential for application of inorganic conjugated semiconductor materials in energy storage 89–91 . It was found that the basic tectonic units that establish allotropes of g‐C 3 N 4 are triazine (C 3 N 3 ) and tri‐s‐triazine/heptazine (C 6 N 7 ) rings 92,93 …”

Solvent‐free selective oxidation of ethylbenzene with molecular oxygen catalyzed by cobalt catalysts supported on exfoliated carbon nitride

“…As a novel carbon‐based material, graphitic carbon nitride (g‐C 3 N 4 ) has been extensively used as a catalyst and/or catalytic support in numerous heterogeneous reactions in past decades [21–23] . The abundant nitrogen‐containing functionalities in the framework of g‐C 3 N 4 enable it to be an ideal support to anchor and disperse many metals [24–25] . More importantly, the chemical valence and dispersion of metal species can be facilely adjusted by the preparation condition of the g‐C 3 N 4 catalysts [26–27] .…”

[24][25] More importantly, the chemical valence and dispersion of metal species can be facilely adjusted by the preparation condition of the g-C 3 N 4 catalysts. [26][27] Very recently, our group has successfully prepared g-C 3 N 4 -based catalysts loaded with a variety of metals including Zn, [28] K, [29] Zr, [30][31] etc, and investigated their catalytic performance in transesterification, cycloaddition of CO 2 and Knoevenagel condensation reactions.…”

Solvent‐Free Selective Oxidation of Benzyl Alcohol at Atmospheric Pressure Catalyzed by Pd Nanoparticles Supported on g‐C3N4 Materials with Tunable Nitrogen Distributions

“…Graphitic carbon nitride (g‐C 3 N 4 ) has emerged as an appealing functional material in a variety of research fields in the past decade [13] . Owing to its combination of multiple physicochemical properties, g‐C 3 N 4 has now been applied in photocatalysis, [14–15] thermocatalysis, [16–17] fuel cell, [18] etc. One particular feature is the abundant nitrogen‐containing functionalities in the framework of g‐C 3 N 4 , which are responsible for its intrinsic basicity [17,19] .…”
