Abstract

This study utilized the activated carbon fiber (ACF), modified with Au, Mn, Ni metals, via the PVD process (ACF/PVD) to diminish ozone. The results indicate that the ozone removal efficiency of the ACF/PVD is better than those of the blank ACF, and the ACF modified with metal catalyst via impregnation process (ACF/impregnation). The gap observed in the efficiency of ozone removal by the ACF/impregnation is possibly caused by the nitrate solution, and the heating practice applied during the impregnation process. These could potentially damage the structure of the ACF. The ozone removal efficiency of the different metal-coated ACF/PVD, in the order of superiority, is gold (Au), manganese (Mn), and nickel (Ni) respectively. The increase of Au-coated thickness (3nm to 8Onm) on ACF/PVD will enhance the ozone removal efficiency. However, when the Mn-coated thickness on ACFIPVD is larger than 1 Snm, the ozone removal efficiency displays a declining trend. Finally, further material analysis of the ACF/PVD, and the ACF/impregnation will be carried out as future research. The above data will also be helpful for expanding on the results from this study.
