Gold supported on metal-doped ceria catalysts (M=Zr, Zn and Fe) for the preferential oxidation of CO (PROX)
A series of ceria oxides doped with 10 mol.% of Zr, Zn and Fe has been prepared by a pseudo sol‐gel method throughout the thermal decomposition of the corresponding metallic propionates. With these supports, 1 wt.% gold catalysts were prepared by the deposition-...
Versatility and multifunctionality of highly reflecting Bragg mirrors based on nanoparticle multilayers
The use of both supported and flexible self-standing nanoparticle-based one dimensional photonic crystal films as effective frequency selective filters in the UV-vis-NIR is herein evaluated. The requirements to achieve a flat spectral response at the desired frequency...
Oxidation state and local structure of Ti-based additives in the Reactive Hydride Composite 2LiBH4 + MgH2
Nowadays, the technological utilization of Reactive Hydride Composites (RHC) as hydrogen storage materials is limited by their reaction kinetics. However, addition of transition metal based additives, for instance titanium isopropoxide (Ti-iso), to the 2LiBH4+MgH2...
Ionic liquid templated TiO2 nanoparticles as a support in gold environmental catalysis
This work presents the synthesis of a nanostructured titania support and its subsequent utilization for the gold particles deposition and application in the reaction of the CO oxidation. A functionalized ionic liquid has been used as a templating agent for the...
