Crucial support effect on the durability of Pt/MgAl2O4 for partial oxidation of methane to syngas

, 2018
Catalyst durability is one of the major problems hindering the commercialization of partial oxidation of methane (POM) for syngas production. We report that a Pt/MgAl2O4-HS catalyst with the MgAl2O4-HS support being synthesized via hydrolysis ...

Structural and optical properties of Eu3+-activated MgAl2O4 for red-emitting phosphor applications

Discover Chemistry
Magnesium aluminate (MgAl2O4) nanophosphor doped with 10 wt% europium (Eu3+) was successfully synthesized via the sol-gel technique. X-ray diffraction analysis confirmed the formation of a single-phase cubic spinel structure, with an average crystallite ...

Thermoluminescent processes of MgAl2O4 irradiated at room temperature.

Physical review. B, Condensed matter, 2013
Two non-first-order kinetic peaks at about 350 and 500 K appear in the thermoluminescence (TL) spectra of single-crystal and polycrystalline MgAl2O4 irradiated with ionizing radiation at room temperature. Among others, emission from Cr3+ and Mn2+ ions are observed.

Synthesis of an Al/MgAl2O4 in situ metal matrix composite from silica gel

, 2007
An aluminum/MgAl2O4 in situ metal matrix composite has been synthesized using silica gel containing B98% SiO2 in an Al–5Mg alloy. The thermodynamics and kinetics of MgAl2O4 formation have been discussed in detail.
