The invention there is provided a process for manufacturing nano-structured zinc oxide tetrapods, wherein pre-cleaned pure zinc granules are subjected to heating in a pre-heated muffle furnace maintained at a temperature in the range of 940 to 980°C for a period in the range of 4 to 6minutes. The evaporated zinc in vapour phase reacts with the atmospheric oxygen present in the said muffle furnace to form zinc oxide. This zinc oxide in vapour phase is allowed to deposit on a pre-cleaned non-reactive substrate, which can with stand the furnace temperature. The deposit on the said substrate is a fluffy white material of nano-structured zinc oxide tetrapods. In the process of the invention nano-structured zinc oxide tetrapods have been produced by thermal evaporation under atmospheric conditions.
