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.application/pdf34623 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所金一氧化碳一氧化碳氧化一氧化碳防毒口 罩二氧化鈦批次生產氧化鋁陶瓷纖維GoldCarbon MonoxideCO OxidationCO Gas MarkTitanium DioxideMass ProductionAluminaCeramic Fiberreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/29432/1/932622E002014CC3.pdf
