Mesoporous titanium carbonitride derived from mesoporous C3N5 for highly efficient hydrogen evolution reaction

Nitrogen‐rich graphitic carbon nitride (g‐C3N5): Emerging low‐bandgap materials for photocatalysis

“…Gujral et al constructed g‐C 3 N 5 with porous structures, which could significantly enhance catalytic activities due to aiding more active sites for reactions and improving mass transport in the system. [ 33 ] They prepared mesoporous g‐C 3 N 5 heterostructured with TiO 2 to produce H 2 . The expressing surface areas of the synthesized materials were reported at 415–445 m 2 g −1 with the distribution profiles of pore sizes and volumes at 4.7–6.5 nm and 0.7–1.2 cm 3 g −1 , respectively.…”

Multifunctional carbon nitride nanoarchitectures for catalysis

“…Keeping in mind the exponential surge in energy demand per capita, to provide next-generation citizens with fossil fuel-free renewable green energy for the creation of a circular economic system, the role of catalysis is crucial as it can provide a powerful platform for the production of clean energy through sustainable pathways, [4][5][6] Therefore, the industry and research community are vigorously looking out for highly efficient and economically suitable catalytic processes that require highly active, stable, and low-cost catalysts. In most of the existing catalytic processes, including oxygen/hydrogen evolution reactions (for green energy), 7 the oxygen reduction reaction, 8 water oxidation, nitrogen reduction, CO 2 reduction (for generating renewable fuels), [9][10][11] and single atom catalysis, 12 various catalytic materials (primarily metallic or metalorganic) have been developed and implemented over the last few decades. However, these materials are costly and suffer from various drawbacks such as poor stability and not being eco-friendly.…”

Engineered g-C3N5-Based Nanomaterials for Photocatalytic Energy Conversion and Environmental Remediation

“…The tetravalent cobalt oxide performed a vital role, whereas the other species made a minor contribution. In addition, Vinu’s team [ 34 ] synthesized mesoporous titanium carbonitride, named MTiCN. It was obtained by carbonizing the mixture of mesoporous C 3 N 5 and titanium tetrachloride at 900 °C for 5 h. The resulting MTiCN samples have a rod-like morphology, a mesoporous structure, and a large specific area, as well as a high carbon content.…”
