Abstract

Two-dimensional nano-crystals, nanosheets, are a new special type of nanomaterials recently discovered. They have attracted interest due to their unique potential applications especially in electronics. In this mini review, we present the current status of liquid exfoliation of layered crystals — an original new method of production of nanosheets. This “top down” synthesis is a low-temperature physico-chemical process already used to graphene production.

Abstract

Coal is a natural energy resource which is mainly used for energy production via combustion. Coal has nanocrystals embedded in it, formed during the coalification process, and is an ideal precursor for nano-carbon dots and diamonds. Herein, we report a facile top-down method to synthesise nanodots and diamonds of the size of 5 nm to 10 nm from three different types of coal by simple chemical leaching. TEM analysis revealed the formation of a mixture of carbon dots, graphene layers, and quantum dots in bituminous coal and sub-bituminous coal. Raman analysis confirmed the existence of synthesized nanodiamond and nano-carbon mixed phase with defects associated with it. It is concluded that graphene quantum dots, nanodiamonds, graphene sheets and carbon dots present in coal can be extracted by simple chemical treatment. These structures can be tuned to photoluminescent material for various optoelectronic applications or energy harvesting devices like super capacitors.

Abstract

Ultrafine Co3O4 nanoparticles homogeneously attached to graphene sheets by sonochemical method have been demonstrated as a promising cathode material for magnesium batteries. X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) have been employed to characterize the structural properties of this material. SEM analyses clearly confirmed that the Co3O4 nanoparticles have been uniformly coated on the entire surface of graphene sheets to form a compact composite. The Co3O4-graphene nanocomposite was employed as a cathode electrode in magnesium-ion batteries, and their electrochemical properties were briefly investigated. The graphene sheets can also effectively buffer the volume change in Co3O4 upon magnesium insertion/extraction, thus improving the cycling preformance of the composite electrode. It was revealed that the Co3O4-graphene composite can provide a small capacity of 16 mAh·g-1 using a new nonaqueous electrolyte that is tetrahydrofuran-free, which provides a new direction to explore cathode materials for Mg batteries.

Present work describes the influence of silver nanoparticles precursor form as well as the impact of graphene oxide initial concentration on deposition of the silver nanoparticles onto graphene oxide. Borane dimethylamine complex (DMAB) was used as the reducing agent. It was observed that application of silver ammonia complexes as the silver nanoparticles precursor as well as alkaline solution effect in higher quantity of deposited AgNPs in comparison to deposition process with the use of silver(I) nitrate in acidic solution.
