Abstract
There are two objectives of this thesis; the first one is to develop a preparation process for manufacturing nano-gold catalyst supporting on the titanium dioxide powder, the second one is to improve the capability of nano-gold catalyst supporting on the fiber materials. For the manufacturing nano-gold catalyst supporting on the titanium dioxide powder, one optimum preparation process was developed from this research, which is preparing 7.5 × 10 -3 M gold solution with 10 g titanium dioxide powder in a 250 ml glass or PP container, operating at room temperature and filtrating with regular filter paper. One can follow this process and scale it up to obtain high catalytic activity for CO oxidation nano-gold catalyst supporting on the titanium dioxide powder. Although the catalytic activity of nano-gold catalyst supporting on the fiber materials isn’t high enough to reach the standard of commercialized gas mask. Nevertheless, all the results of the second part could be important references to improve the capability of nano-gold catalyst supporting on the fiber materials. From the results, the composition of the fiber could be the most important factor which affects the character of the catalysts.
