16. PHOTOCATALYSIS
- the acceleration of a photoreaction in
the presence of a catalyst.
- Activation using UV radiation of
titanium dioxide
17. Why Titania?
- It can either be diffused in the irradiated
solution as slurry or attached on a
suitable support as a fixed or fluidized
bed.
18. Requirements for a good Titania supporting material
(a) transparent to UV;
(b) favor strong physical-chemical bond
with the TiO2 without affecting their
reactivity;
(c) offer a high surface area;
(d) have good adsorption capability for
the organic compounds to be
degraded;
19. Requirements continued…
(e) flexible favoring the ultimate liquidsolid phase separation;
(f) allow mass transfer processes;
(g) chemically inert.
21. 2. Deposition of TiO2 by PECVD
magnetron setup using Compact Plane
Magnetron (CPM) at the Plasma
Physics Laboratory - National Institute
of Physics (PPL-NIP).
33. Conclusion
TiO2-coated cheesecloth is
low-cost
support
wastewater treatment
light reactive
material
in
current methods used to deposit TiO2 on
cloth generate acidic and chemical wastes
simple (one-step-process) and
environmentally friendly.
