Table 2. Surface Area of the Various ZnO Supports Useda.
| support | surface area /m2 g–1 |
|---|---|
| Acros ZnO | 6 |
| Sigma Aldrich ZnO | 15 |
| Farag method ZnO | 26 |
| Precipitation ZnO33 | 78 |
| P25 TiO2 | 55 |
Note that the final support in this list was made by depositing Pd and Zn (in a 1:10 ratio) onto titania by CVI in order to have an intermediate surface area. In that case, the titania is covered by ZnO. Characterization of that material is given elsewhere.24
