Outline of Final Research Achievements

Various metal oxides were prepared in silica pores having pore size of around 1～2 nm. Two important results were shown as follows: (1) Application of the nano hexavalent Cr species in porous silica matrix for VOC control at wide range of reaction temperatures from room temperature. (2) Synergistic connecting effect of TiO2 and WO3 quantum dots on the photocatalytic activity.
