| 英文摘要 | it is well established that adding methanol to water could significantly enhance h-2 production by tio2. recently, we have found that methanol can be photocatalytically dissociated on tio2(110) at 400 nm via a stepwise mechanism. however, how molecular hydrogen can be formed from the photocatalyzed methanol/tio2(110) surface is still not clear. in this work, we have investigated deuterium formation from photocatalysis of the fully deuterated methanol (cd3od) on tio2(110) at 400 nm using a temperature programmed desorption (tpd) technique. photocatalytic dissociation products formaldehyde (cd2o) and o-atoms on bbo sites (via d2o tpd product) have been detected. in addition to d2o formation by heating the photocatalyzed methanol/tio2(110) surface, we have also observed d-2 product formation. o-2 is dearly formed via thermal recombination of the o-atoms on the bbo sites from photocatalysis of methanol. experimental results indicate that d2o formation is more important than d-2 formation and that d-2 formation is clearly affected by the d2o formation process. |
