Graphene quantum dots is a class of graphene nanomaterials with exceptional luminescence properties. Precise dimension control produced by chemical synthesis methods currently difficult to achieve and usually provides range sizes from 3 25 nm. In this work, fullerene C60 used as starting material, due its well-defined dimension, produce very small (∼2-3 nm). Treatment mixture strong acid oxidant induced the oxidation, cage-opening, fragmentation processes C60. The synthesized were...
Graphene oxide composites with photocatalysts may exhibit better properties than pure via improvement of their textural and electronic properties.TiO2-Graphene Oxide (TiO2 - GO) nanocomposite was prepared by thermal hydrolysis suspension graphene (GO) nanosheets titania peroxo-complex. The characterization provided using an atomic force microscope Raman spectroscopy. nanocomposites samples were characterized Brunauer-Emmett-Teller surface area Barrett-Joiner-Halenda porosity, X-ray...
Nanometric particles of pure brookite TiO2 were synthesized by modified thermolysis reactant solutions containing titania powder, HCl, urea and PEG 10000. Unique flower-like agglomerates with an average diameter ∼400–450 nm composed single nanocrystals ∼4–5 obtained at 105 °C. The → rutile transformation has been studied mixtures variable amount anatase, polymorphs different temperatures (from 200 to 800 °C) obtained. High resolution transmission electron microscopy (HRTEM), diffraction...
Silicon nanocrystals are an extensively studied light-emitting material due to their inherent biocompatibility and compatibility with silicon-based technology. Although they might seem fall behind rival, namely, direct band gap based semiconductor nanocrystals, when it comes the emission of light, room for improvement still lies in exploitation various surface passivations. In this paper, we report on original way, taking place at temperature ambient pressure, replace silicon oxide shell...
Molybdenum-doped anatase was prepared by thermal hydrolysis of peroxotitanium complex aqueous solutions containing a molybdenum peroxo-complex. The synthesized samples were characterized X-ray diffraction, high-resolution transmission electron microscopy, selected area and surface (BET) porosity (BJH) determination. Molybdenum doping caused the increase unit cell constants changes in morphology particles from spindle-like shapes to with rectangular or square cross sections. presence...
Thin films of MAX and MXene phases were prepared by ion beam sputtering followed thermal annealing in vacuum. For this purpose, a Low Energy Ion Facility (LEIF) using heavy ions for target irradiation was developed, the DC method implemented. The process preparing thin composites consists two steps. First step: bombarding elemental targets with low-energy (either all together, each corresponding size, or separately repeatedly); it results synthesis either homogeneous layers mixed multilayer...
Zinc sulfide (ZnS) nanoparticles were prepared by homogeneous hydrolysis of zinc sulfate and thioacetamide (TAA) at 80 degrees C. After annealing a temperature above 400 C in oxygen atmosphere, oxide (ZnO) obtained. The ZnS ZnO characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission (HRTEM), selected area (SAED), Brunauer-Emmett-Teller (BET)/Barrett-Joyner-Halenda (BJH) methods used for surface porosity determination. photocatalytic activity...
