The Study on Metal Nanopowders Synthesis in a High Boiling

Abstract:

As a result of testing the large number of organic liquids, it was established that benzyl alcohol is the most suitable medium for the reduction of nickel compounds. This is a monohydric aromatic alcohol; its composition is described by formula С6H5−CH2−CH2OH. Benzyl alcohol has not very high boiling point (205 °C), the catalytic activity of nickel is low under these conditions, so the negative consequences of dehydrogenation become noticeable only if the process duration is tens hours. At the same time, the reducing potential of benzyl alcohol turned out to be rather high. In application of nickel carboxylates, the time of complete reduction did not exceed 3-4 hours, which allowed us to obtain high-purity nickel powders. Further development of the investigation showed that benzyl alcohol can be successfully used also to reduce the salts of other metals: copper, bismuth, silver, cobalt.
