introduce the use of pure molten ortho-phosphoric
acid (o-H3PO4) as an electrolyte
for self-organizing electrochemistry. This electrolyte allows for
the formation of self-organized oxide architectures (one-dimensional
nanotubes, nanochannels, nanopores) on metals such as tungsten that
up to now were regarded as very difficult to grow self-ordered anodic
oxide structures. In this work, we show particularly the fabrication
of thick, vertically aligned tungsten oxide nanochannel layers, with
pore diameter of ca. 10 nm and illustrate their potential use in some
typical applications.
