We
report a simple and versatile strategy for hybridizing 1-D silver
trimolybdate wires (Ag<sub>2</sub>Mo<sub>3</sub>O<sub>10</sub> Ws)
and graphene oxide (GO) by a direct solution process. Because of the
photoactive nature of Ag<sub>2</sub>Mo<sub>3</sub>O<sub>10</sub> Ws,
Ag particles were uniformly formed on their surfaces with the assistance
of solar light. Enriched surface functional groups of GO from chemical
activation induce a chemical coordination with these Ag particles.
As a result, a uniform ternary hybrid mixture was successfully formed
with metallic Ag nanoparticles as a bridge connecting activated GO
and Ag<sub>2</sub>Mo<sub>3</sub>O<sub>10</sub> Ws. We found that both
excited GO and Ag<sub>2</sub>Mo<sub>3</sub>O<sub>10</sub> could generate
electron/hole pairs separated in space by metallic Ag as a solid-state
electron mediator. The novel photocatalytic mechanism was confirmed
using photocurrents, the electronic-band structure, and photoactivity
correlation analysis.
