| 中文摘要 | effect of defects on photocatalytic dissociation of methanol on tio2(110) |
| 英文摘要 | photocatalytic dissociation of deuterated methanol (cd3od) on both stoichiometric and reduced tio2(110) surfaces was investigated using the time-dependent two-photon photoemission (2ppe) method, in order to understand the effect of defects on the kinetics of methanol dissociation on tio2(110). by monitoring the time evolution of the photoinduced excited state on the methanol covered surface, the photocatalytic dissociation kinetics of methanol on the tio2 surface were observed. the measured photodissociation rate on the reduced tio2(110) surface is more than an order of magnitude faster than that on the stoichiometric surface. since the reduced tio2(110) surface has considerably more surface and subsurface defects than the stoichiometric surface, the experimental observation suggests that one or both of them could accelerate the photocatalysis process of methanol on the tio2(110) surface in a significant way. |
