Photocatalytic performance of porous TiO2 layers prepared by quantitative electrophoretic deposition from organic solvents

Original language description

Highly-crystalline TiO2 nanoparticles coated on a suitable substrate make excellent photocatalysts for environmentalnapplications. While electrophoretic deposition is frequently used to prepare such layers on a conductivensupport, this method often requires the presence of an additive to suppress nanoparticle agglomerationnand increase particle surface charge. However, the presence of an additive can lead to contamination that negativelynaffects layer properties. To overcome this drawback, we developed an optimized electrophoretic methodnfor the preparation of porous TiO2 layers, whose photocatalytic performance in the degradation of a toxicncompound was analyzed. Our method enabled TiO2 layers (anatase, rutile and their mixture) to be quantitativelyndeposited on rigid substrates (stainless steel, FTO-glass and silicon wafers) without sintering and without the usenof a dispersive additive. The photocatalytic performance of layers depended on the structural properties ofntitania particles, especially their allotropic form (anatase vs. rutile) and crystallinity, and on the presents ofndefects within the crystals. For well-developed crystals of anatase phase a high rate of the degradation of 4-nchlorophenol and its almost complete mineralization were achieved. Owing to their excellent properties,nespecially stability and photocatalytic performance, the layers prepared by EPD are suitable for a broad range ofnenvironmental applications.
