| 英文摘要 | we have investigated the photoinduced decomposition of formaldehyde (ch2o) on tio2(110) at 400 nm using temperature-programmed desorption. formate (hcoo), methyl radicals (ch3), and ethylene (c2h4) have been detected, while no evidence of polymerization of ch2o was found. the initial step in the decomposition of ch2o on tio2(110) is the formation of a dioxymethylene intermediate in which the carbonyl o atom of ch2o is bound both to a ti atom on the five-fold-coordinated lattice site (ti-5c) and to a nearby bridge-bonded oxygen (bbo) atom. during 400 nm irradiation, the dioxymethylene intermediate can transfer methylene to the bridging oxygen row and break the c-o bond, thus leaving the original carbonyl o atom on the ti-5c site. after this transfer of methylene, several pathways to products are available. thus we have found that bbo atoms are intimately involved in the photoinduced decomposition of ch2o on tio2(110). |
