“…7, the Nyquist plots of the three NMCO electrodes consist of a semicircle and a diagonal line, showing the typical characteristics of LIBs. 40 A general equivalent circuit diagram is obtained via fitting the Nyquist plots of the three NMCO electrodes using ZSimpWin software. The equivalent circuit consists of R s , R ct , Q , and C ( R s : sum of the contact resistance and the ionic resistance, R ct : charge transfer resistance, Q : constant phase angle element and C : intercalation capacitance).…”

“…To analyze the differences of CN and CCN, X-ray diffraction (XRD) patterns, Fourier transformed infrared (FTIR) spectra, Raman spectra, and X-ray photoelectron spectroscopy (XPS) spectra are compared first. The XRD pattern of CN displays strong characteristic peaks at 13.1 and 27.5° matching with the (100) and (002) planes of pure g-C 3 N 4 (Figure b) . They are ascribed to interlayer stacking and in-planar repeated tri-s-triazine units .…”

Owing to low cost and high theoretical capacity, g-C 3 N 4 is known as the potential anode in sodium ion battery. However, its poor electronic conductivity and structural stability hinder its actual performance. Here, a simple gel coating− calcination method is used to get a g-C 3 N 4 @carbon composite (CCN). Benefiting from the increased pyridinic-N content and electronic conductivity and the fluffy and porous structure, CCN shows a high discharge capacity of 250/183 mAh g −1 at 0.1/3 A g −1 and a long-term cycling performance with 180 mAh g −1 over 1600 cycles at 0.5 A g −1 . Moreover, a CCN//Na 3 V 2 (PO 4 ) 3 full battery exhibits good cycling stability.

“…Over the past few years, changes in the salt‐precursor ratio and tuning the parameters of the reaction have allowed the production of various g‐C 3 N 4 structures. [ 103,104 ] The ionothermally produced g‐C 3 N 4 material's enhanced crystallinity is responsible for its excellent photocatalytic ability. This, in turn, could improve charge separation and transport, thereby increasing the overall photocatalytic activity.…”

A Comprehensive Review on Graphitic Carbon Nitride for Carbon Dioxide Photoreduction

Inspired by natural photosynthesis, harnessing the wide range of natural solar energy and utilizing appropriate semiconductor‐based catalysts to convert carbon dioxide into beneficial energy species, for example, CO, CH4, HCOOH, and CH3COH have been shown to be a sustainable and more environmentally friendly approach. Graphitic carbon nitride (g‐C3N4) has been regarded as a highly effective photocatalyst for the CO2 reduction reaction, owing to its cost‐effectiveness, high thermal and chemical stability, visible light absorption capability, and low toxicity. However, weaker electrical conductivity, fast recombination rate, smaller visible light absorption window, and reduced surface area make this catalytic material unsuitable for commercial photocatalytic applications. Therefore, certain procedures, including elemental doping, structural modulation, functional group adjustment of g‐C3N4, the addition of metal complex motif, and others, may be used to improve its photocatalytic activity towards effective CO2 reduction. This review has investigated the scientific community's perspectives on synthetic pathways and material optimization approaches used to increase the selectivity and efficiency of the g‐C3N4‐based hybrid structures, as well as their benefits and drawbacks on photocatalytic CO2 reduction. Finally, the review concludes a comparative discussion and presents a promising picture of the future scope of the improvements.
