applications. While electrophoretic deposition is frequently used to prepare such layers on a conductive
support, this method often requires the presence of an additive to suppress nanoparticle agglomeration
and increase particle surface charge. However, the presence of an additive can lead to contamination that negatively
affects layer properties. To overcome this drawback, we developed an optimized electrophoretic method
for the preparation of porous TiO2 layers, whose photocatalytic performance in the degradation of a toxic
compound was analyzed. Our method enabled TiO2 layers (anatase, rutile and their mixture) to be quantitatively
deposited on rigid substrates (stainless steel, FTO-glass and silicon wafers) without sintering and without the use
of a dispersive additive. The photocatalytic performance of layers depended on the structural properties of
titania particles, especially their allotropic form (anatase vs. rutile) and crystallinity, and on the presents of
defects within the crystals. For well-developed crystals of anatase phase a high rate of the degradation of 4-
chlorophenol and its almost complete mineralization were achieved. Owing to their excellent properties,
especially stability and photocatalytic performance, the layers prepared by EPD are suitable for a broad range of
environmental applications.Pracoviště Ústav fyzikální chemie J.Heyrovského Kontakt Michaela Knapová, michaela.knapova@jh-inst.cas.cz, Tel.: 266 053 196 Rok sběru 2019
