“…Aghazadeh et al. [ 254 ] obtained g‐C 3 N 4 nanosheets using ultrasonication‐assisted liquid phase exfoliation method and electrochemically co‐embedded them with Co(OH) 2 in a Ni‐foam support using a simple electrodeposition procedure ( Figure a,b). Interestingly, the cyclic voltammetry test diagram demonstrated that the curve shapes of f‐g‐C 3 N 4 /Co(OH) 2 and Co(OH) 2 are similar, but the areas are very different when tested in supercapacitors (Figure 29c,d).…”

Graphitic carbon nitride (g‐C3N4) have attracted great attention in the field of energy conversion and storage due to its unique layered structure, tunable bandgap, metal‐free characteristic, high physicochemical stability, and easy accessibility. 2D g‐C3N4 nanosheets have the features of short charge/mass transfer path, abundant reactive sites and easy functionalization, which are beneficial to optimizing their performance in different fields. However, the reviews of the comprehensive applications of 2D g‐C3N4 for energy conversion and storage are rare. Herein, this review first introduces the physicochemical properties of bulk g‐C3N4 and g‐C3N4 nanosheets, and then summarizes the synthetic strategies of 2D g‐C3N4 nanosheets in detail, such as thermal oxidation etching, chemical exfoliation, ultrasonication‐assisted liquid phase exfoliation, chemical vapor deposition, and others. Emphasis is focused on the rational design and development of 2D g‐C3N4 nanosheets for the diversified applications in energy conversion and storage, including photocatalytic H2 evolution, CO2 reduction, electrocatalytic H2 evolution, O2 evolution, O2 reduction, alkali‐metal ion batteries, lithium‐metal batteries, lithium–sulfur batteries, metal‐air batteries, and supercapacitors. Finally, the current challenges and perspectives of 2D g‐C3N4 nanosheets for energy conversion and storage applications are discussed.
