Different Dimensionalities, Morphological Advancements and Engineering of g‐C₃N₄‐Based Nanomaterials for Energy Conversion and Storage

Abstract Graphitic carbon nitride (g‐C 3 N 4 ) has gained tremendous interest in the sector of power transformation and retention, because of its distinctive stacked composition, adjustable electronic structure, metal‐free feature, superior thermodynamic durability, and simple availability. Furthermore, the restricted illumination and extensive recombination of photoexcitation electrons have inhibited the photocatalytic performance of pure g‐C 3 N 4 . The dimensions of g‐C 3 N 4 may impact the field of electronics confinement; as a consequence, g‐C 3 N 4 with varying dimensions shows unique features, making it appropriate for a number of fascinating uses. Even if there are several evaluations emphasizing on the fabrication methods and deployments of g‐C 3 N 4 , there is certainly an insufficiency of a full overview, that exhaustively depicts the synthesis and composition of diverse aspects of g‐C 3 N 4 . Consequently, from the standpoint of numerical simulations and experimentation, several legitimate methodologies were employed to deliberately develop the photocatalyst and improve the optimal result, including elements loading, defects designing, morphological adjustment, and semiconductors interfacing. Herein, this evaluation initially discusses different dimensions, the physicochemical features, modifications and interfaces design development of g‐C 3 N 4 . Emphasis is given to the practical design and development of g‐C 3 N 4 for the various power transformation and inventory applications, such as photocatalytic H 2 evolution, photoreduction of CO 2 source, electrocatalytic H 2 evolution, O 2 evolution, O 2 reduction, alkali‐metal battery cells, lithium‐ion batteries, lithium–sulfur batteries, and metal‐air batteries. Ultimately, the current challenges and potential of g‐C 3 N 4 for fuel transformation and retention activities are explored.
