An environmental friendly route to synthesize titanium dioxide nanotube powder is developed using a semi‐batch reactor set‐up that combines both anodization and the plasma treatment of water. A constant supply of the reactive plasma species, such as nitrate and hydrogen peroxide, in the semi‐batch reactor facilitates the formation of titanium dioxide nanotubes during the anodization of titanium. The results are compared against a conventional batch reactor set‐up that uses the same plasma‐treated water constantly during the anodization, which impacts the quality of the nanotubes produced. The semi‐batch reactor set‐up resulted in the formation of powders of titanium dioxide nanotubes with better physical and chemical qualities than those produced in the batch set‐up.
