Special Issue Information

Dear Colleagues,

In the face of growing environmental concerns and energy crises driven by the extensive combustion of fossil fuels, the quest for high-performance materials that can facilitate the use of clean and renewable energy sources has never been more urgent. Within this context, carbon-based materials have emerged as promising candidates due to their versatile properties and the abundant opportunities they present for functionalization and structural design.

In this Special Issue, we invite investigators to contribute original research articles and review articles that delve into the design and application of these fascinating materials. We are particularly interested in studies that focus on morphological regulation, functional design, and macro integration. In addition, we welcome explorations into photo/electrocatalytic reactions, such as the oxygen reduction reaction, CO2 reduction, and N2 fixation, as well as light-electricity coupling systems and other potential applications that leverage the unique properties of these materials.

The key areas of interest for this Special Issue include, but are not limited to:

  • Carbon-based materials;
  • Functionalization;
  • Active sites;
  • Structural design;
  • Morphological control;
  • Photocatalysis;
  • Electrocatalysis.

Through this Special Issue, we aim to highlight the cutting-edge research that is pushing the boundaries of our understanding and application of carbon-based materials in the field of photo/electrocatalysis.

We look forward to your valuable contributions to this exciting and rapidly developing field.

The binary heterostructured semiconducting visible light photocatalyst of the iron-doped graphitic carbon nitride/bismuth molybdate (Fe-g-C3N4/Bi2MoO6) composite was prepared by coupling with Fe-doped g-C3N4 and Bi2MoO6 particles. In the present study, a comparison of structural characteristics, optical properties, and photocatalytic degradation efficiency and activity between Fe-doped g-C3N4 particles, Bi2MoO6 particles, and Fe-g-C3N4/Bi2MoO6 composite was investigated. The results of X-ray diffraction (XRD) examination indicate that the hydrothermal Bi2MoO6 particles have a single orthorhombic phase and Fourier transform infrared (FTIR) spectroscopy analysis confirms the formation of Fe-doped g-C3N4. The optical bandgaps of the Fe-doped g-C3N4 and Bi2MoO6 particles are 2.74 and 2.73 eV, respectively, as estimated from the Taut plots obtained from UV-Vis diffuse reflectance spectroscopy (DRS) spectra. This characteristic indicates that the two semiconductor materials are suitable for absorbing visible light. The transmission electron microscopy (TEM) micrograph reveals the formation of the heterojunction Fe-g-C3N4/Bi2MoO6 composite. The results of photocatalytic degradation revealed that the developed Fe-g-C3N4/Bi2MoO6 composite photocatalyst exhibited significantly better photodegradation performance than the other two single semiconductor photocatalysts. This property can be attributed to the heterostructured nanostructure, which could effectively prevent the recombination of photogenerated carriers (electron–hole pairs) and enhance photocatalytic activity. Furthermore, cycling test showed that the Fe-g-C3N4/Bi2MoO6 heterostructured photocatalyst exhibited good reproducibility and stability for organic dye photodegradation. Full article
