Resumen

Nanostructured films of cadmium hexacyanoferrate (III), Cd ₃[Fe(CN) ₆] ₂ have been deposited on the surface of titanate nanotubes (TiNT) by ion exchange with CdSO ₄, followed by reaction with K ₃[Fe(CN) ₆] in an aqueous suspension. The composite demonstrates a significantly higher hydrogen storage uptake than pure Cd ₃[Fe(CN) ₆] ₂ and TiNT. At a temperature of 77 K and a pressure 100 bar, the hydrogen uptake for the composite is approximately 12.5 wt %, whereas only 4.5 wt % and 4 wt % are achieved for the TiNT and Cd ₃[Fe(CN) ₆] ₂ respectively. Electron microscopy and infrared spectroscopy show that Cd ₃[Fe(CN) ₆] ₂ is uniformly distributed on the surface of the nanotubes forming a discontinuous nanostructured film with a well developed interface, which allows efficient interaction with the support. The possible reasons for the high uptake of hydrogen in the composite are discussed.
