Abstract

Highly macroporous thin films of WO3 were fabricated on transparent conductive substrates by application of a polymeric organic paste loaded with an amine/tungstate complex.  After spin-coating and annealing at 550oC, the resulting yellow films are found to be comprised of channeled array of clustered nanoparticles.  These channels are confirmed by scanning electron microscopy to extend through the entire length of the coating.  The high porosity of the material enables the insertion of a co-catalyst into the internal structure of the film.  These internally functionalized composites demonstrate good photosensitivity and stability in neutral electrolyte.
