A Targeted Review of Current Progress, Challenges and Future Perspective of g‐C₃N₄based Hybrid Photocatalyst Toward Multidimensional Applications

Abstract

The increasing demand for searching highly efficient and robust technologies in the context of sustainable energy production totally rely onto the cost-effective energy efficient production technologies. Solar power technology in this regard will perceived to be extensively employed in a variety of ways in the future ahead, in terms of the combustion of petroleumbased pollutants, CO 2 reduction, heterogeneous photocatalysis, as well as the formation of unlimited and sustainable hydrogen gas production. Semiconductor-based photocatalysis is regarded as potentially sustainable solution in this context. g-C 3 N 4 is classified as non-metallic semiconductor to overcome this energy demand and enviromental challenges, because of its superior electronic configuration, which has a median band energy of around 2.7 eV, strong photocatalytic stability, and higher light performance. The photocatalytic performance of g-C 3 N 4 is perceived to be inadequate, owing to its small surface area along with high rate of charge [a] A

Efficient Photocatalytic Cleavage of C–C Bonds in β-1 Lignin Models and Aromatic Vicinal Diols by Combining Alkali Metal-Treated Graphitic Carbon Nitride and Persulfate

“…Photocatalyst graphitic carbon nitride (BCN) is a nontoxic and inexpensive nonmetallic photocatalyst. 32 It has a visiblelight-driven band gap and can withstand water-based environments. Secondary pollution from commonly used metal photocatalysts can be prevented by BCN, which is a significant advantage of BCN in practical applications.…”

“…36,37 g-C 3 N 4 has received great attention in the field of photocatalysis because of its extraordinarily high conductivity, dielectric strength and high photocatalytic activity. 38,39 Other advantages of g-C 3 N 4 are its low cost and high thermal stability (∼600 °C). 40 The g-C 3 N 4 /TiO 2 combination has enhanced activity.…”

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

“…[62] With the exception of g-C 3 N 4 , the CNs are all very strong material based on their crystalline structure. [63][64][65][66][67] Most intriguingly, g-C 3 N 4 exhibits the stacking 2D layering composition seen in Figure 1b. Moreover, two separate condensed water regions were illustrated as principal structural in a standard matrix of g-C 3 N 4 systems, s-triazine components (r-C 3 N 3 ) with a periodic arrangement of singular C vacant positions; and tri-s-triazine/ heptazine substituents (t-C 6 N 7 ) linked via rectangular tertiary amide cluster with massive periodic vacant positions in the structure.…”

“…Teter and Hemley anticipated five distinct forms of CN in 1996, comprising α‐CN, β‐CN, c‐CN, p‐CN, and g‐CN (Figure 1a). [62] With the exception of g‐C 3 N 4 , the CNs are all very strong material based on their crystalline structure [63–67] . Most intriguingly, g‐C 3 N 4 exhibits the stacking 2D layering composition seen in Figure 1b.…”
