Production and Evaluation of Porous Photocatalyst Concrete Filter (deNOx PCF) for NOx Reduction
Table 4
Results of comparative evaluation of NO reduction by each different specimen.
| | | Total supplied NO amount (μmol) | NO reduction amount (μmol/h) | Total NO removal rate (%) |
| | Portland cement concrete filter (no porous, no TiO2) | 8.22 | 0.09 | 1.06 | | Lightweight aerated concrete filter (porous, no TiO2) | 8.26 | 0.32 | 3.88 | | deNOx PCF (porous, 3% of TiO2) | 9.36 | 1.03 | 10.99 | | deNOx PCF (porous, 5% of TiO2) | 9.24 | 0.58 | 6.28 |
