to its non-toxicity, powerful oxidation strength, high chemical stability and low cost
(Lee et al., 2007). These nanoparticles have great prospective as water-treatment redox-
catalysts material due to their large surface area and their size and shape dependent
optical, electronic and catalytic properties (Obare and Meyer, 2004). Figure 11.5(I)
