内容記述 |
Due to its chemical/thermal stability, metal-free nature, abundance, low toxicity, cost-effectiveness, high surface area, tunable properties, and ease of synthesis, graphitic carbon nitride (g-C3N4) is a promising material for applications in catalysis, sensing, energy storage and optoelectronics. By virtue of its optical band gap, g-C3N4 has been extensively used to drive a range of photocatalytic reactions, such as H2 generation, CO2 reduction, N2 fixation, and organic transformation, to name a few. Despite these prospects, significant improvement in extending its optical absorption is essential because g-C3N4 absorbs light only up to 460 nm (≈10% of the incoming sunlight). Thus, reducing its band gap to harness a wider part of the sunlight is a key approach to advancing the solar energy conversion efficiency of g-C3N4. In this direction, the effect of (i) improving the degree of polymerization, (ii) molecular and elemental doping, (iii) distorting planar structure, (iv) inducing nitrogen vacancies, and (v) tuning the C/N ratio of g-C3N4 on red-shifting the optical absorption is analyzed in detail. A comprehensive correlation between the synthesis approach/conditions–structure–optical property is established. Rational guidelines on extending the spectral response of g-C3N4 toward the visible/near-infrared region and using low-energy photons to drive photocatalytic reactions efficiently are detailed. The insights presented will help to utilize the full potential of g-C3N4 to enhance the solar fuel generation efficiency and in understanding the mechanism of light absorption. |
