Metal oxides have a large storage capacity when employed as anode materials for lithium-ion batteries (LIBs). However, they often suffer from poor capacity retention due to their low electrical conductivity and huge volume variation during the charge–discharge process. To overcome these limitations, fabrication of metal oxides/carbon hybrids with hollow structures can be expected to further improve their electrochemical properties. Herein, ZnO-Co3O4 nanocomposites embedded in N-doped carbon (ZnO-Co3O4@N-C) nanocages with hollow dodecahedral shapes have been prepared successfully by the simple carbonizing and oxidizing of metal–organic frameworks (MOFs). Benefiting from the advantages of the structural features, i.e. the conductive N-doped carbon coating, the porous structure of the nanocages and the synergistic effects of different components, the as-prepared ZnO-Co3O4@N-C not only avoids particle aggregation and nanostructure cracking but also facilitates the transport of ions and electrons. As a result, the resultant ZnO-Co3O4@N-C shows a discharge capacity of 2373 mAh g−1 at the first cycle and exhibits a retention capacity of 1305 mAh g−1 even after 300 cycles at 0.1 A g−1. In addition, a reversible capacity of 948 mAh g−1 is obtained at a current density of 2 A g−1, which delivers an excellent high-rate cycle ability.

Graphene-metal oxide composites as supercapacitor electrodes combine the large pseudocapacitance of metal oxides with the fascinating electrical and mechanical properties and large surface area of graphene. The synthetic methods for composites are reviewed, including in-siu synthesis, solution mixing, hydrothermal method, microware irradiation and electrochemical deposition. Among these techniques, the hydrothermal method offers an effective and simple way to anchor metal oxides on the 2D graphene sheet uniformly. Consequently, the composites exhibit high capacity, high rate capability and well reversibility, presenting promising prospects as supercapacitor electrode material.

Palladium single-crystal films have been prepared by Matthews in ultra-high vacuum by evaporation onto (001) NaCl substrates cleaved in-situ, and maintained at ∼ 350° C. Murr has also produced large-grained and single-crystal Pd films by high-rate evaporation onto (001) NaCl air-cleaved substrates at 350°C. In the present work, very large (∼ 3cm2), continuous single-crystal films of Pd have been prepared by flash evaporation onto air-cleaved (001) NaCl substrates at temperatures at or below 250°C. Evaporation rates estimated to be ≧ 2000 Å/sec, were obtained by effectively short-circuiting 1 mil tungsten evaporation boats in a self-regulating system which maintained an optimum load current of approximately 90 amperes; corresponding to a current density through the boat of ∼ 4 × 104 amperes/cm2.
