We present lightweight macro-mesoporous spinel CoAl2O4 nanostructured aerogels derived from water-soluble aluminum-chitosan complexes. Chitosan nanofibrils interact with aluminum ions to swell into hydrogels. The aluminum-induced swelling is extended to dissolve the hydrogels in water to form a homogeneous aluminum-chitosan aqueous solution. The addition of cobalt ions in the aluminum-chitosan liquids which are solidified by lyophilization to generate cotton-like aerogel composites. Uniform incorporation of cobalt-aluminum hydroxide ions onto chitosan leads nanofibrils to serve as a hierarchical template to support mixed metal hydroxides in the aerogel composites. We investigated the thermal removal of chitosan template in the composites to obtain spinel CoAl2O4 aerogels that truly replicate spider web-like fibrillar networks of chitosan template. Enlarged porosity, high crystallinity, and lightweight make the CoAl2O4 aerogels useful as a colorful nano-pigment for magnetic ceramics.

Electrodeposited environmental and energy-saving electrodeposited copper alloys materials without silver element will be one of the hotspots on the exploitation of the copper matrix electrical contact field. Theoretically expression of Cu, W, Co and Cu-W-Co alloys electrodeposition possibility is thermodynamically analyzed by the potential-pH plots of Cu-H2O,Co-H2O and W-H2O at normal temperature. It is found that Cu, Co can be deposited together in Cu2+,Co2+aqueous solution. Cu-W isn’t deposited from it’s Cu2+,WO42-aqueous solution, only if Co-W induced deposition under the cobalt ions’ circumstances. So, It is possible that Cu-W-Co alloys are prepared from Cu2+,Co2+,WO42-aqueous solution by the electrodeposition in the theory and experiment, which will be new method and theory for Cu-W-Co serial contact materials’ preparation.
