Formatted abstract

The photocatalytic properties of TiO2 have been investigated extensively for the past 3 decades. It is still considered a relatively new technology with many questions left unanswered. The process of photocatalysis is a classical combination of Chemical Engineering and Environmental technology. It is basically an advance oxidation process, which involves the illumination of UV photons on to semi-conducting catalyst like TiO2 or ZnO. . Upon contact with VOCs (Volatile Organic Compound), the oxidation process will disintegrate the harmful organic structure into CO2 and H2O.

The primary objective of this project is to study the effect and performance of the photocatalysts after it had been subjected to paint formulations by addition of paint binders, which serves to hold and bind colour pigments together. Due to the highly oxidative nature of the catalyst, most of the conventional binders will be disintegrated by the photocatalytic action in no time. It is therefore the aim to study the right kind of binders and formulation to achieve the optimum results. Unfortunately, due to time constrain, this part of the experiment was not able to be completed. However, initial findings from the author had shown that the photocatalytic performance after the addition of binders had not been comparable to the performance of catalyst without any bindings.

It is also the aim of this project to investigate the performance of a patented formulation of TiO2 that had been awarded to the University of Queensland. Comparison will be made with 6 commercially acquired samples. This will also act as a form of control experiment in order to compare the performance of the binder-loaded catalyst.

No variations were seen with respect to the rate of reaction constant and half - life. However, in the comparison of the UQ’s TiO2, the initial adsorption rate and the overall rate of degradation was found to be 3 times higher than the rest of the acquired catalyst samples.
