Resumen
La adsorción de un derivado triamínico de pirimidina (AMNTRENH) en un nanotubo multicapa (MWCNT) permite obtener un material híbrido tipo MWCNT/AMNTRENH que se utilizó como material de partida para obtener posteriormente complejos estables anima-metal soportados sobre la superficie del MWCNT. Esto se hizo por adsorción sobre un material híbrido del tipo MWCNT/AMNTRENH de iones metálicos Ni(II) y PD(II).
[EN]The adsorption of a pyrimidine-based triamine derivative, AMNTRENH, on a multiwall nanotube (MWNT) to obtain a hybrid solid material MWCNT/AMNTRENH was considered a suitable procedure to prepare after stable amine-metal complexes adsorbed on MWCNT surface. This was done by adsorption on an hybrid material, MWCNT/AMNTRENH, the (Ni(II) and Pd(II) metal ions. Reduction of the so adsorbed metal ion with NaBH4 in water, yields well disperded Pd(0) nanoparticles on the MWCNT surface in the case of Pd(II). On the contrary the supported Ni(II)-amino complexes show high stablility to NaBH4 reduction.
