Abstract

Copper oxalate nanowires inside the channels of mesoporous SBA-15 are created by in-situ oxidation of block copolymer in as-prepared SBA-15 samples. The pyrolysis of CuC₂O₄/SBA-15 composites under different conditions results in the formation of CuO or Cu₂O nanowires encapsulated in the nanoscale channels. The appearance, structure and composition of these materials are characterized by the X-ray power diffraction, transmission electron microscopy, N₂ adsorption-desorption isotherms, infrared spectra and inductive coupled plasma emission spectra. CuC₂O₄, CuO and Cu₂O nanomaterials filled in the channels of SBA-15 have been proven to possess the electrochemical hydrogen storage capacities of 102, 165 and 231 mAh/g in the second cycle, respectively, and are expected to have a high potential for use in practical applications.
