摘要: Photocatalytic oxidations (PCOs) of heptane, trichloroethylene (TCE), ethanol, acetaldehyde, and toluene were carried out on sulfated TiO2 (SO42−/TiO2) and Degussa P-25. Coverages of all organics on SO42−/TiO2 were significantly higher than on P-25, but P-25 was more active for PCO at room temperature. Pulse PCO at room temperature suggests that steady-state PCO rates of acetaldehyde on the two catalysts may be similar, however. During PCO of heptane at room temperature, SO42−/TiO2 deactivated slower than P-25 so …
