Synthesis of Ca-doped spinel by ultrasonic spray pyrolysis
(ElsevierAmsterdam, 2016)
MgAl2O4 is a stable catalyst support with potential for replacing gamma-alumina in several applications. However, synthesis of magnesium spinel requires elevated temperatures to avoid phase separation (in MgO and Al2O3) ...
Identifying different states of lithiation of Li4Ti5O12spinel by energy-dispersive inelastic X-ray scattering (EDIXS) spectroscopy
(Royal Society of Chemistry, 2020-12)
The Li4Ti5O12 (LTO) compound has been investigated as an alternative negative electrode material for lithium ion batteries (LIBs), which are being used as energy storage devices in stationary systems as well as for electric ...
Electrospinning synthesis and characterization of nanofibers of Co, Ce and mixed Co-Ce oxides. Their application to oxidation reactions of diesel soot and CO
(Elsevier Science, 2020-12)
Co, Ce and Co-Ce nanofibers were synthesized by the electrospinning method. To obtain mixed fibers, Co was incorporated in two ways: one step synthesis and sequential synthesis. Nanofibers were applied to two reactions: ...
Magnetic properties of spindle-type iron fine particles obtained from hematite
(2001-12-01)
Spindle-type iron fine particles have been prepared by reduction of silica-coated-hematite particles. Hydrogen reduction of the coated-hematite cores yielded uniform spindle-type iron particles, which were stabilized by ...

Spindle-type iron fine particles have been prepared by reduction of silica-coated-hematite particles. Hydrogen reduction of the coated-hematite cores yielded uniform spindle-type iron particles, which were stabilized by ...
Spinel ferrites as catalysts for light alkanes combustion
(Nova Science Publishers, 2013)
The Spinel Ferrites of general formula MIIFe2 IIIO4 are advanced ceramics suitable for many technical applications. The preparation of such materials as nanoparticles is of high interest because these exhibits unique ...
Cobalt based catalysts for CO Preferential Oxidation
(IntechOpen, 2019)
In this work, catalysts based oncobalt supported on ZrO2 and CeO2, and CoCeMnOx were studiedfor the CO preferential oxidation (COPrOx) in rich-hydrogen stream able to feedfuel cells. Among them, the CoCeMnOx formulation ...
Espinela Li2CoTi3O8 nanométrica obtenida para aplicación como pigmento
(2016-01-01)
Pigments are used in ceramics, cosmetics, inks, and other applications widely materials. To this must be single and easily reproducible. Moreover, the pigments obtained in the nanoscale are more stable, reproducible and ...
