Selective synthesis and novel properties of single crystalline α-CoMoO4 nanorods/nanowhiskers

The selective controlled syntheses of crystalline CoMoO4 nanorods (rod-CoMoO4)/nanowhiskers (whiskers-CoMoO4) by using reverse micelles in different molar ratios (w) of [H2O]/[CTAB] under mild hydrothermal conditions are reported for the first time. The obtained rod-CoMoO4/whiskers-CoMoO4 have a monoclinic structure (α-CoMoO4), with diameter range from 10 to 80 nm and their lengths range from several tens of nanometers to 1 μm. The synthesis conditions and formation mechanism of the nanorods/nanowhiskers were discussed. The electrochemistry behaviors of Co2+ and CoMoO4 in nanoscale and in macroscale are compared, from which an interesting result is obtained. Furthermore, the efficient antibacterial property of the nanorods against Escherichia coli (E. coli) was first found.
