Epimerization of glucose over ionic liquid/ phosphomolybdate hybrids: structure-activity relationship
The influence of the crystal structure and chemical nature of some ionic liquid/phosphomolybdate hybrids on their catalytic activity in the epimerization of glucose was studied. A clear evidence of structure–activity relationship was found. The inorganic part of the...
Cobalt Carbide Identified as Catalytic Site for the Dehydrogenation of Ethanol to Acetaldehyde
Two cobalt catalysts, Co/SBA-15 and Co/SiO2, have been studied in steam reforming of ethanol (SRE). Besides the steam reforming products, ethoxide dehydrogenation to acetaldehyde is observed as one of the main reactions. Although by hydrogen treatment cobalt is...
Photonic Tuning of the Emission Color of Nanophosphor Films Processed at High Temperature
Photonics offers new possibilities to tailor the photoluminescence process in phosphor-converted light emitting diodes. Herein, it is demonstrated that the emission color of thin layers of rare-earth doped nanocrystals can be strongly modulated in tunable spectral...
Design and Realization of a Novel Optically Disordered Material: A Demonstration of a Mie Glass
Herein, a diffusive material presenting optical disorder isintroduced, which represents an example of a Mie glass. Comprising spherical crystalline TiO2 nanoparticles randomlydispersed in a mesoporous TiO2 matrix, it is proved that thescattering of light in this...
