Catalytic properties of the samples used in entries 4–9.
| Entry | Support | Loadinga [wt%] | Average diameter [nm] | T 1/2 [°C] | TOFb [mol s−1 nm−1] |
|---|---|---|---|---|---|
| 4 | SZ-NPG | 0.89 (1.0) | 7.3 | 26 | 9.54 × 10−24 |
| 5 | SZ-NPG | (3.0) | 14.1 | 28 | (1.06 × 10−23) |
| 6 | TiO2 | (1.0) | 6.1 | 10 | (9.51 × 10−24) |
| 7c | ZrO2 | 0.84 | 9.1 | 117 | 5.24 × 10−25 |
| 8c | SiO2 | 0.75 | 7.7 | >200 | 1.13 × 10−25 |
| 9d | TiO2 | 0.15 | 3.0 | 29 | 1.06 × 10−23 |
a
Actual loading detected via ICP-AES, and the values in parenthesis are estimated based on the quantity of the Au precursor used.
b
Reaction rate per nanometre of Au perimeter (active site of CO oxidation) at 25 °C. The values in parenthesis are calculated using the Au loading estimated from the quantity of the Au precursor.
c
The samples were used for creating Fig. 2 in our prior study,22 although the specific values for the Au loading, diameter, and TOF were not reported in that study.
d
The sample is the same as sample 2 reported in a previous study.29
