Special Issue Information

Dear Colleagues,

During the last few decades, sustained efforts to develop innovative synthesis paths have resulted in a wide range of carbon nanostructures (such as carbon nanotubes, fullerenes, carbon horns, and graphenes), providing the resources for new nanocomposite materials with outstanding physical features for advanced applications in energy (production and storage), catalysis, and sensors. This endeavor has generated new emerging materials with multifunctional features (self-healing, shape memory) and led to the development of new applications. Recent research suggests a similar path for phosphorus and phosphorus-based nanoparticles and their nanocomposites. This Special Issue aims to provide a forum for the latest achievements made both in the fundamental and applied fields of nanomaterials and composite materials based on carbon and phosphorous.

We are pleased to invite you to submit original research articles and reviews to this issue.

Potential topics include but are not limited to:

  • Composites based on various inorganic/organic/macromolecular compounds and carbon nanoparticles of the type carbon nanotubes, carbon nanohorns, graphene oxide, reduced graphene oxide, graphene quantum dots and fullerene;
  • Phosphorene layers and black phosphorus quantum dots functionalized with macromolecular compounds;
  • New aspects concerning the optical, electrical, structural and electrochemical properties of carbon and phosphorus nanoparticles as well as their composites;
  • Graphene and phosphorene sheets modified with metallic nanoparticles as new surface-enhanced Raman scattering supports;
  • Applications of carbon and phosphorus nanoparticle-based composites for energy storage (supercapacitors, batteries, fuel cells);
  • Applications of carbon and phosphorus nanoparticles in the hydrogen production and storage field;
  • Applications in the solar cells field and photocatalysis;
  • Sensorial platforms based on composites containing the carbon or phosphorus nanoparticles.

We look forward to receiving your contributions.

In this work, applications of nanohybrid composites based on titanium dioxide (TiO2) with anatase crystallin phase and single-walled carbon nanohorns (SWCNHs) as promising catalysts for the photodegradation of amoxicillin (AMOX) are reported. In this order, TiO2/SWCNH composites were prepared by the solid-state interaction of the two chemical compounds. The increase in the SWCNH concentration in the TiO2/SWCNH composite mass, from 1 wt.% to 5 wt.% and 10 wt.% induces (i) a change in the relative intensity ratio of the Raman lines located at 145 and 1595 cm−1, which are attributed to the Eg(1) vibrational mode of TiO2 and the graphitic structure of SWCNHs; and (ii) a gradual increase in the IR band absorbance at 1735 cm−1 because of the formation of new carboxylic groups on the SWCNHs’ surface. The best photocatalytic properties were obtained for the TiO2/SWCNH composite with a SWCNH concentration of 5 wt.%, when approx. 92.4% of AMOX removal was achieved after 90 min of UV irradiation. The TiO2/SWCNH composite is a more efficient catalyst in AMOX photodegradation than TiO2 as a consequence of the SWCNHs’ presence, which acts as a capture agent for the photogenerated electrons of TiO2 hindering the electron–hole recombination. The high stability of the TiO2/SWCNH composite with a SWCNH concentration of 5 wt.% is proved by the reusing of the catalyst in six photodegradation cycles of the 98.5 μM AMOX solution, when the efficiency decreases from 92.4% up to 78%.

The emergence and fast development of carbon dots (CDs) provide an unprecedented opportunity for applications in the field of photoelectricity, but their practicability still suffers from complicated synthesis procedures and the substrate dependence of solid-state fluorescence. In this study, we design a unique microwave-assisted solid-phase synthesis route for preparing tunable fluorescent CD powders with yellow, orange, and red fluorescence (Y-CDs, O-CDs, R-CDs) by simply adjusting the mass ratio of reactants, a method which is suitable for the large-scale synthesis of CDs. The Y-/O-/R-CDs were systematically characterized using physics and spectroscopy techniques. Based on the perfect solid-state fluorescence performance of the proposed fluorescent CD powders, the Y-/O-/R-CDs were successfully applied for the construction of multi-color and white light-emitting diode devices at low cost. Furthermore, the Y-CDs displayed much higher yield and luminous efficiency than the O-CDs and R-CDs and were further used for fingerprint identification on the surfaces of glass sheets and tinfoil. In addition, the R-CD aqueous solution fluorescence is sensitive to pH, suggesting its use as a pH indicator for monitoring intracellular pH fluctuations. The proposed series of fluorescent powders composed of CDs may herald a new era in the application of optical components and criminal investigation fields. Full article
