Graphitic Carbon Nitride Film: An Emerging Star for Catalytic and Optoelectronic Applications

“…These can be classified into two types: bottom‐up and top‐down approaches. Bottom‐up techniques include thermal vapor condensation (TVC), direct growth, microcontact printing, solvothermal method, and electrodeposition . Top‐down techniques include depositing g‐CN powders or nanosheets onto a substrate .…”

“…Xie et al. have developed a solvothermal method by using acetonitrile as the solvent and acetonitrile and melamine as the precursors, as described in Figure e . The precursor solutions are kept at 180 °C for 24 h. The g‐CN film is grown in the Stranski–Krastanov growth mode; this begins with a two‐dimensional layer‐by‐layer mode but evolves into a three‐dimensional microsphere stacking mode.…”

“…[70,71] Techniques for the deposition of g-CN films on solid substrates have emerged very recently.T hese can be classified into two types:b ottom-up and top-down approaches. Bottomup techniques include thermalv apor condensation (TVC), [72][73][74] direct growth, [75][76][77][78] microcontactp rinting, [79] solvothermal method, [80] ande lectrodeposition.

Relative to films synthesized by other methods, this film has much larger grains (Figure 2f).…”

“…[66] Eine weitere Mçglichkeit besteht im Aufsprühen einer wässrigen Suspension von exfoliertem CN unter Verwendung eines kommerziellen Befeuchters. Beispiele umfassen PEDOT-PSS, [77][78][79] Nafion [62,78,80,81] und andere. [71] Diese Verfahren bieten großes Potenzial zum Hochskalieren.…”
