Special Issue Information

Dear Colleagues,


Graphitic carbon nitride has recently emerged as a versatile material in the field of materials and catalysis. It is one of the members of carbon nitride family with general formula of C3N4. It can be prepared by several precursors such as urea, thiourea, cyanamide, dicyandiamide and melamine. Due to the semiconductor property of carbon nitride, it shows photocatalytic activity and acts as a photocatalyst for various kinds of reactions. Moreover, presence of nitrogen atoms in its skeleton adds Lewis and Bronsted basic properties to it. Graphitic carbon nitride is considered a good material for hydrogen storage and has also been used as support for various metal catalysts.

In this special issue, we invite scholarly articles on recent advancement in the area of graphitic carbon nitride based catalysts. The topics covered in this special issue may range from heterogeneous catalysis, photocatalysis, photoelectrocatalysis, CO2 conversion, metal free catalysis, hydrogen release or storage, and biomass conversion catalyzed by graphitic carbon nitride.

A straightforward process for hydrodebenzylation of benzyl protected acid and alcohol derivatives to the corresponding acids and alcohols using sodium hypophosphite in the presence of Ru-GCN catalyst is reported. The developed Ru-GCN catalyst is cost effective compared to other noble metal-based catalysts and has been explored to exhibit excellent activity for catalytic hydrodebenzylation reactions under moderate reaction conditions. The non-corrosive sodium hypophosphite has been found as a better hydrogen donor compared to alkali metal formats in presence of Ru-GCN catalyst. The stated catalyst was characterized using several spectrometric and material characterization methods such as PXRD, IR, SEM, TEM, XPS, and TGA. The Ru-GCN catalyst corroborated good reusability and stability for multiple cycles. The catalyst preparation is facile and the developed process is simple and safe as it avoids use of high hydrogen pressure. The developed protocol can also be replicated on industrial scale on account of excellent recyclability and retained activity after multiple cycles and makes the process sustainable. Gram scale reaction was performed to verify the industrial potential of reported catalyst. Full article

The construction of highly efficient, low-cost and noble-metal-free photocatalysts depends on photocatalytic technology. Recently, N-rich C3N5 has been explored as a novel carbon nitride material with a much narrower band gap (~2.2 eV) than that of traditional C3N4 (~2.7 eV). Planting noble-metal-free active sites on C3N5 to improve its photocatalytic activity is of great significance. Herein, 2D NixSy nanosheet is facially loaded on 2D C3N5 using a hydrothermal procedure under a low temperature. Due to the quick separation of photogenerated carries between C3N5 and NixSy, this inexpensive noble-metal-free NixSy-C3N5 hybrid nanosheet is highly efficient and stable as a multifunctional catalyst in various applications, including photocatalytic H2 production from water and NO removal. Impressively, the apparent quantum yield (AQY) value for H2 production reaches 37.0% (at 420 nm) on optimal NixSy-C3N5 hybrids, which is much higher than that of Pt-C3N5 material. This work opens an avenue to the fabrication of low-cost and noble-metal-free catalysts for multifunctional photocatalytic applications. Full article
