Abstract
We explore the conversion of free-standing Cu nanowire arrays produced by electrodeposition in polymer etched ion-track membranes into metal-organic frameworks KHUST-1 by electrochemical oxidation. HKUST-1 particles are built up when the as-formed Cu2+ ions bind to the benzene tricarboxylic acid ligands (BTC3-) in the electrolyte solution. The morphology and crystallinity of the samples at different transformation stages are investigated by scanning and transmission electron microscopy. X-ray diffraction data taken at different conversion times confirm the formation of HKUST-1 particles. The conversion process resulted in octahedral structures of several mu m in size. Comparison of the Raman spectra with the band positions derived from density functional theory (DFT) calculations, suggests that vibrations involving Cu atoms appear only below 490 cm(-1) wavenumbers and involve the entire HKUST-1 lattice rather than vibrations of single bonds.
