In-situ oxidation of block copolymer for producing copper oxalate or copper oxide nanowires in mesoporous channels
- Department of Chemistry, East China Normal University, ShangHai City 200062 (China)
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 CuC{sub 2}O{sub 4}/SBA-15 composites under different conditions results in the formation of CuO or Cu{sub 2}O 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, N{sub 2} adsorption-desorption isotherms, infrared spectra and inductive coupled plasma emission spectra. CuC{sub 2}O{sub 4}, CuO and Cu{sub 2}O 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. - Graphical abstract: Copper oxalate or copper oxide nanowires embedded in the nanoscale channels of mesoporous SBA-15 are created by in-situ oxidation of block polymer template materials, which show the good electrochemical hydrogen storage ability.
