ESR

ESR 如何能够看出激子的寿命？ The ESR data are shown in Fig. 6. It can be seen that the total intensity of hydroxyl radical (?OH) species and superoxide radical (O2 ?2) species as detected over the CeO2-NT sample is higher than that over the CeO2-NP and commercial P25 nanoparticles. In addition, it should be noted that, upon light irradiation, the O2 ?2 radical species are clearly observed over only the CeO2-NT sample but they are not observed over the samples of P25 and CeO2-NP. These suggest the prolonged lifetime of electron–hole pairs generated over the sample of CeO2-NT upon light irradiation. As a result, as reflected in Fig. 6, a greater amount of radical species with strong oxidation power, including ?OH species and superoxide radical O2 ?2 is able to be photogenerated over the CeO2-NT than its counterpart CeO2-NP and commercial P25 nanoparticles. This in turn explains reasonably why the higher photocatalytic activity of CeO2 nanotubes than CeO2 and P25 nanoparticles has been observed toward the gas-degradation of benzene, as schematically shown in Fig. 7. |

Electron spin resonance (ESR) spectra were measured using a Bruker A300 EPR electron paramagnetic resonance spectrometer equipped with a quanta- Ray Nd:YAG laser system as their radiation light source (l = 254 nm). The settings were the center field at 3480.00 G, microwave frequency at 9.83 GHz, and power at 6.35 mW. |
