Nanostructured materials have been studied intensively due to their board potential applications in the energy field. A great deal of effort has been devoted to developing high efficient nanocatalysts for oxygen reduction reaction (ORR). In [...]
One of the key issues for polymer electrolyte membrane fuel cells (PEMFCs) is to reduce or replace expensive Pt cathode catalysts. Although the development of non-Pt, such as Pd-Co catalysts for the oxygen reduction reaction [...]
In order to further enhance photoeletrocatalytic reactivity, it is desirable to develop a facile and effective technique to obtain high quality Pd@TNTAs with homogeneous dispersion and small enough particle size down to few of nm [...]

This work has as aim the development of Ni catalysts supported in α-Al2O3/ZnO, Al2O3/Fe2O3 and Al2O3/ZrO2 to be applied in to catalytic reaction of the steam reforming of the methane. The Al2O3/ZnO, Al2O3/Fe2O3 and Al2O3/ZrO2 [...]
We present a method that allows proper control of the nanoscale curvature of the external surface in multiwall carbon nanotubes (MWCNT) and shown its effect on the properties of Ni/MWCNT catalyst. After removal of residual [...]
