A wet-chemical method was employed to prepare zinc oxide nanocrystals having controlled morphology through thermal decomposition of a precursor in self-assembled supramolecular structures solvent under mild conditions. This solution offers finer tailoring the size and shape is complementary most reported physical methods. Understanding morphological effects pure or modified on photocatalytic activity important regard enhanced solar energy capture utilization but has been scarcely addressed...
We present a novel and facile synthetic method for fabricating graphitic carbon nanostructures (GCNs) from sawdust. This is based on the use of catalysts (Fe or Ni) that allows direct conversion sawdust into highly graphitized material. The following procedure was used to obtain these nanoparticles: (a) impregnation particles with iron nickel salts, (b) carbonization impregnated material at temperature 900 1000 °C, (c) selective removal non-graphitized (amorphous carbon) by an oxidant...
ZIF-8 is a zeolitic imidazolate framework with very good thermal and chemical stability that opens up many applications are not feasible by other metal-organic frameowrks (MOFs) zeolites. Several works report the adsorption properties of for strategic gases. However, despite vast experimental corpus data reported, there seems yet to be dearth in understanding gas properties. In this work we provide insights at molecular level on mechanisms governing structural deformation during adsorption....
We present here a novel and simple synthetic strategy for fabricating core/shell materials (diameter ∼400 nm) made up of inorganic nanoparticles confined within hollow mesoporous carbon shell (shell thickness ∼50 nm). This methodology has been applied to the encapsulation variety phases such as Fe3O4/γ-Fe2O3, CoFe2O4, LiCoPO4, NiO, Cr2O3. An important characteristic these composites is that, whereas inner macroporous core can be almost completely filled by nanoparticles, porosity hardly...
We present a novel and facile synthesis methodology for obtaining graphitic carbon structures from Fe(II) Co(II) gluconates. The formation of can be carried out in only one step by means heat treatment these organic salts at temperature 900 °C or 1000 under inert atmosphere. This process consists the following steps: (a) pyrolysis gluconate its transformation to amorphous carbon, (b) conversion Fe2+ Co2+ ions Fe2O3 CoO their subsequent reduction metallic nanoparticles (c) fraction formed Fe...
We present a method to produce superparamagnetic iron oxide/silica nanocomposites that have large BET surface area, high pore volume, and at least one size population centered around or larger than 10 nm. By means of this methodology, which is based on nanocasting techniques, we are able not only prepare mesoporous with adequate sizes magnetic properties for enzyme immobilization but also explore various phenomena associated the characteristics matrixes. Magnetic ordered mesostructured...
We present here a synthetic method for fabricating hollow magnetic mesoporous nanocomposites (diameter ∼ 400 nm) made up of ferrite nanoparticles incorporated to the shell (shell thickness 50 carbon capsules. This methodology has been applied insertion different ferrites such as iron oxide spinel (Fe3O4/γ-Fe2O3), CoFe2O4, NiFe2O4, and MnFe2O4. The size these inorganic (∼9−17 can be modulated easily by varying temperature synthesis, demonstrated in case phase. An important characteristic is...
