Engineering metal organic frameworks for heterogeneous catalysis.
In conclusion, MOFs as Host Matrices or Nanometric Reaction Cavities should not be considered as a source of concern in the determination of MOFs’ properties in relation to other materials. Expand
Hierarchically mesostructured doped CeO2 with potential for solar-cell use
The preparation of a hierarchically structured mesoporous material from nanoparticles of CeO2 of strictly uniform size is reported, which possesses large pore volumes, high surface areas, and marked thermal stability, allowing it to be easily doped after synthesis whilst maintaining textural and mechanical integrity.

Influence of excitation wavelength (UV or visible light) on the photocatalytic activity of titania containing gold nanoparticles for the generation of hydrogen or oxygen from water.
For the novel visible light photoactivity of Au/TiO(2), it has been determined that gold loading, particle size and calcination temperature play a role in the photocatalytic activity, the most active material being the catalyst containing 0.2 wt % gold with 1.87 nm average particle size. Expand
Semiconductor behavior of a metal-organic framework (MOF).
Upon light excitation MOF-5 behaves as a semiconductor and undergoes charge separation (electrons and holes) decaying in the microsecond time scale, and photoinduced electron transfer processes to viologen generates the corresponding viologens radical cation. Expand
Titania supported gold nanoparticles as photocatalyst.
The central part of this article is focused on the photocatalytic activity reported for Au/TiO(2) for hydrogen generation, dye decoloration, phenol decomposition and carboxylic acid degradation, among other processes. Expand
Catalytic activity of palladium supported on single wall carbon nanotubes compared to palladium supported on activated carbon: Study of the Heck and Suzuki couplings, aerobic alcohol oxidation and
Abstract Nanoparticles (2–10 nm) of palladium have been deposited on single wall carbon nanotubes (SWNT) by spontaneous reduction from Pd(OAc)2 or from oxime carbapalladacycle. These catalystsExpand
Gold-copper nanoalloys supported on TiO2 as photocatalysts for CO2 reduction by water.
A mechanism in which the role of Au is to respond under visible light and Cu binds to CO and directs the reduction pathway is proposed. Expand
Metal nanoparticles as heterogeneous Fenton catalysts.
This Review summarizes the use of metal nanoparticles, either unsupported or deposited on large-surface-area solids, as Fenton catalysts, and particular emphasis is given to the reaction conditions in which these catalysts are used. Expand
