Most of the examples of metal MOFs and metaloxides MOFs discussed up to now have been synthesized in order to obtain novel kinds of supported nanoparticles with potentially advantageous properties for applications in catalysis. The catalytic properties of the composite materials Pd MOF-5 and Cu MOF-5 were among the first to be tested. The Pd MOF-5 composite that was obtained by the gas phase loading/photolysis synthetic protocol (35.6 wt% Pd) showed moderate activity in catalysis of hydrogenation of cyclooctene [59], The Pd MOF-5 (1 wt%) synthesized by the incipient wemess technique from [PdCacac) ] was tested as catalyst in hydrogenation of styrene, 1-octene and c/x-cyclooctene, and exhibited a shghtly higher catalytic activity than Pd supported on activated carbon (Pd/Norit A Fig. 23) [51].

We have recently reported on the preparation of Pd NPs encapsulated in zirconium-containing UiO-66 and UiO-67 materials (with terephthalate and biphenyldicarboxylate ligands, respectively). The procedure used consisted in the gas phase loading of a Pd precursor, [Pd(T -C3H5)( n -C5H5)], followed by the controlled decomposition by UV irradiation [21]. This method led to the formation of small NPs (1-2 nm) located mainly inside the pore cages of... 

The most common and the fastest techniques for hydrogenation of the rare earth metals is by gas phase loading where H2 is injected into the chamber with the rare earth metal film and pumped out periodically. The hydrogenation performed in H2 ambient is better reproducible, and well suited for exploratory work but suffers from the disadvantage that the quantitative monitoring of the amount of hydrogen getting incorporated in the film on an absolute scale is not possible. Moreover it is not practical for device operation. 

The transmittance and reflectance of SmH3 5 film (55 nm) capped with Pd (2.5 nm) hydrogenated via gas phase loading is given in fig. 41. Neglecting the contribution from the Pd over layer, the refractive index and extinction coefficient were determined from the measured... 

The modifications in the hydrogen induced optical, electronic and structural properties of Gd-Mg alloy films have been studied by utilizing both the gas phase loading as well as electrochemical loading. The Gdi Mg alloy films (200 nm) with 0.1 < z < 0.9, capped with...
