Study results from Anhui Normal University provide new insights into crystallography

  2008 NOV 24 - (VerticalNews.com) -- "In this paper, we report a simple and novel coordination compound precursor route to synthesize the hierarchical dumbbell-like CoOOH nanostructures in high yield. A possible growth mechanism governing the formation of such nanostructures is discussed," researchers in Wuhu, People's Republic of China report.

  "The CO-gas-sensing properties of the as-synthesized nanostructures are investigated in detail. The dumbbell-like CoOOH nanostructures have a large active surface area of {110} facets, which can provide sufficient space for the interaction between CoOOH and the detected gases. As a result, the as-prepared dumbbell-like CoOOH nanostructures exhibit a superior sensitivity to CO at room temperature, as well as good reproducibility and short response/recovery times," wrote B.Y. Geng and colleagues, Anhui Normal University.

  The researchers concluded: "The as-prepared CoOOH nanostructures could have potential applications in nanosensors."

  Geng and colleagues published their study in Crystal Growth & Design (Facile production of self-assembly hierarchical dumbbell-like CoOOH nanostructures and their room-temperature CO-gas-sensing properties. Crystal Growth & Design, 2008;8(10):3497-3500).
