Roles of Mo dopant in BiWO for enhancing photocatalytic activities.

We present the investigation of the roles of molybdenum (Mo) dopant with a concentration of 0.0625% to 1.0% Mo into bismuth tungstate (BiWO) by a one-step hydrothermal method for the enhancement of photocatalytic activities.

A new mechanism of atomic manipulation: bond-selective molecular dissociation via thermally activated electron attachment.

We report a new mechanism of (bond-selective) atomic manipulation in the scanning tunneling microscope (STM). We demonstrate a channel for one-electron-induced C-Cl bond dissociation in chlorobenzene molecules chemisorbed on the Si(111)-7 × 7 surface, at room temperature and above, which is thermally activated. We find an Arrhenius thermal energy barrier to one-electron dissociation of 0.
