Abstract (EN):
Graphitic carbon nitride, g-C3N4, is a polymeric material consisting of C, N,
and some impurity H, connected via tris-triazine-based patterns. Compared with the
majority of carbon materials, it has electron-rich properties, basic surface functionalities
and H-bonding motifs due to the presence of N and H atoms. It is thus regarded as a
potential candidate to complement carbon in material applications. In this review, a brief
introduction to g-C3N4 is given, the methods used for synthesizing this material with
different textural structures and surface morphologies are described, and its
physicochemical properties are referred. In addition, four aspects of the applications of
g-C3N4 in catalysis are discussed: (1) as a base metal-free catalyst for NO decomposition,
(2) as a reference material in differentiating oxygen activation sites for oxidation reactions
over supported catalysts, (3) as a functional material to synthesize nanosized metal
particles, and (4) as a metal-free catalyst for photocatalysis. The reasons for the use of g-
C3N4 for such applications are also given, and we expect that this paper will inspire readers
to search for further new applications for this material in catalysis and in other fields.
