For a catalytic process, I need to synthesize very homogeneous ZnO nanorods, no more than 100 nm in length. Could anyone suggest some effective method? Until now, the synthesis has been carried out by heat treatment of Zn acetate at 300 ºC in air, but there is considerable variability in the sizes obtained. Thanks!
you can synthesise of nano ZnO by refluxing precursor zinc acetate dihydrate (0.1 M) in diethylene glycol and triethylene glycol at 180 °C and 220 °C respectively. Reaction time varied for 2 and 3 h with and without sodium acetate (0.01 M).
You can also modify the synthesis reported here:Article A facile co-precipitation synthesis of heterostructured ZrO2...
by replacing Etanol by methanol and adding water (few droplets) we observed the growth of anisotropic rods smaller than 100nm. Little work needs but it is an easy low T synthesis
Thanks for the suggestion. These days we are testing different alternatives, and this one that you suggest we are also going to test it.
Hello Francisco,
a synthetic route to ZnO nanorods with a narrow size distribution has been reported in the following useful research article:

Fortunately this paper is freely available as public full text and can be downloaded as pdf file.
Good luck with your research and best wishes!
