Annealed Copper

Cu-loaded TiO2 nanotube arrays were fabricated by immersing the anodized nanotube arrays in Cu(NO3)2 solution and then post-annealed. Copper oxide with diameter about 20 nm was loaded on the nanotube arrays with tube diameter about 140 nm, the wall thickness about 40 nm and the length about 4 µm. Cu-loaded TiO2 nanotube arrays showed remarkable improvement of photochemical activity. The photocurrent of Cu-loaded sample soaked in 0.02 M Cu(NO3)2 solution was about 2.5 times higher than that of unloaded sample.

Layered cobalt carbonate hydroxide (LCCH) acicular nanorod arrays (ANRAs) are converted to Co3O4 acicular nanotube arrays (ANTAs) via Kirkendall effect. The Co3O4 ANTAs exhibit a specific capacitance of 979 F g−1, which is higher than that of the Co3O4 ANRAs (191 F g−1).

Good Agreement

Very few electron microscopy papers have been published on the atomic structure of the copper oxide based superconductor surfaces. Zandbergen et al. have reported that the surface of YBa2Cu3O7-δ was such that the terminating layer sequence is bulk-Y-CuO2-BaO-CuO-BaO, whereas the interruption at the grain boundaries is bulk-Y-CuO2-BaO-CuO. Bursill et al. reported that HREM images of the termination at the surface are in good agreement with calculated images with the same layer sequence as observed by Zandbergen et al. but with some oxygen deficiency in the two surface layers. In both studies only one or a few surfaces were studied.
