Esmaielzadeh Kandjani, Ylias M. Sabri, Matthew R. Field, Victoria E. Coyle, Rynhardt Smith, Suresh K. BhargavaCarbon soot is one of the oldest
materials known for its hydrophobic
properties, robustness, and availability, making it an ideal material
for use in various applications. The drawbacks, however, are the loose
structural binding between constructing carbon nanoparticles and the
amorphous nature of soot itself. In this paper, we present a facile
chemical vapor deposition (CVD) method that maintains the soot template
structural integrity and enables its modification into a highly photoactive,
self-cleaning titania fractal network. The results show that the small
air pockets available on the surface combined with the salinization
process produces a TiO2 fractal network with superamphiphobic
properties. Given the high surface area of the fractal network structure
and titania’s well-known photocatalytic activity, the designed
surfaces were assessed for their photocatalytic decoloration activities.
The results showed that the soot template derived TiO2 films
can offer enormous potential in many different applications where
self-cleaning and/or high surface area and photoactive properties
are required.
