Special Issue Information

Dear Colleagues,

Nanocomposites based on graphene leads to materials with high catalytic activity for a variety of chemical transformations. The physical and chemical properties of graphene such as high specific surface area, their extended π-system, and variable functionalities for effective chemical interactions help to convert graphene into advanced nanocomposite materials by incorporating other foreign particles. Graphene and its derivatives such as graphene oxide, highly reduced graphene oxide, or doped graphene are excellent support materials which can fine-tune the surface composition for desired functionalities to enhance the versatility of graphene-based nanocomposites in catalysis.

Many graphene-based materials viz. graphene/inorganic nanoparticles, polymer-based nanocomposites, graphene-encapsulated materials, or core-shell metal chalcogenides/graphene have appealing properties for versatile applications. Additionally, the conductive nature of the graphene contributes in the effective charge transport within the nanocomposites. Overall, the graphene-based nanocomposites become multifunctional materials with enhanced efficiencies.

Although graphene has been explored extensively, the synthesis of graphene-based nanocomposite received less coverage. There is much room to improve synthetic protocols for graphene-based nanocomposites. It is still challenging to prepare these fine-tuned materials at low-cost and large scale. Therefore, research studies advdressing the shape and size controlled synthesis, enhanced surface properties and green chemistry are the major concern. 

Therefore, this special Issue of “Catalysts” is devoted to original research and review articles covering latest innovations in the field of graphene nanocomposites, particularly towards the development of sustainable approaches for the preparation and characterization of nanomaterials and their composites. Apart from this, research and/or review articles related to the diverse application of graphene based nanocomposite in various fields including catalysis, biological and environmental applications are also welcome in this special issue.

The active centers of carbon catalysts doped with cobalt, nickel, copper, manganese, zinc, and chromium were modeled by density functional theory methods. Likewise, the thermodynamics of the oxygen reduction reaction (ORR) on model catalysts were determined. The features of the chemical properties of chromium-containing material, namely its spontaneous oxidation into the hydroxo form, were revealed. In addition, it was established that among the studied catalysts, graphene doped with cobalt showed the best properties. Full article

Hybrid materials based on metal-organic frameworks (MOFs) and nanoparticles (NPs) have gained considerable popularity in a variety of applications. Particularly, these types of materials have demonstrated excellent efficiency in heterogeneous catalysis due to the synergistic effect between the components. Herein, we report a simple, eco-friendly, photocatalytic method for the fabrication of Zr containing MOF-801 and a silver (Ag) NPs-based hybrid ([email protected]). In this method, the photocatalytic property of the central metal ion (Zr) of MOF was exploited to promote the formation and deposition of Ag NPs on the surface of the MOF-801 under the irradiation of visible light. The successful incorporation of Ag NPs was ascertained by powder X-ray diffraction (XRD) and UV-Vis analysis, while the morphology and surface area of the sample was determined by N2 adsorption–desorption and scanning electron microscopy (SEM), respectively. The resulting [email protected] hybrid served as a highly efficient catalyst for the transesterification of used vegetable oil (UVO) for the production of biodiesel. The [email protected] catalyst exhibited superior catalytic activity compared to its pristine MOF-801 counterpart due to the enhanced surface area of the material. Full article
