Graphitic carbon nitride-based nanostructures as emergent catalysts for carbon monoxide (CO) oxidation

Kamel Eid et al.

Summary: Pristine graphitic carbon nitride-based catalysts (g-C3N4) show limitations in practical CO oxidation applications, such as low surface area, sluggish electron transfer, inadequate gas activation, poor electrical conductivity, and weak visible-light absorption. These issues can be addressed by incorporating heteroatoms, metals/metal oxides, and single atoms into g-C3N4 nanostructures, as well as coupling g-C3N4 with other semiconductors to form heterojunction structures. Additionally, electron donation from the g-C3N4 support enhances O-2 adsorption and activation. This review aims to provide a comprehensive understanding of the rational design and challenges of g-C3N4-based catalysts for CO oxidation.

Template-free synthesis of M/g-C3N4 (M = Cu, Mn, and Fe) porous one-dimensional nanostructures for green hydrogen production

Ahmed Abdelgawad et al.

Summary: In this study, we synthesized porous one-dimensional graphitic carbon nitride doped with metal atoms (M/g-C3N4) (M = Cu, Mn, and Fe) for electrochemical and photo-electrochemical hydrogen evolution reaction. The M/g-C3N4 materials were obtained through the direct acidification of metal precursors and melamine solution, followed by pyrolysis under N2 at 550 degrees C. The resulting M/g-C3N4 possessed well-defined pore sizes, nanofiber morphology, high surface area, and desired metal atomic contents. Among Cu/g-C3N4, Fe/gC3N4, and Mn/g-C3N4, Cu/g-C3N4 exhibited the best HER performance in terms of overpotential, onset potential, H2 production rate, and mass/specific activity.
