Monoclinic Ag₂Mo₂O₇ Nanowire: A New Ag–Mo–O Nanophotocatalyst Material

Abstract

We report a template-free facile technique that allows for the first ever synthesis of a <i>monoclinic</i> Ag₂Mo₂O₇ nanowire (m-Ag₂Mo₂O₇-NW), using a commercially available MoO₃ particle. The nanowire possessed high crystallinity and structural homogeneity and strongly suggested that the nanowire was grown through an oriented aggregation mechanism in contrast to the case of a typical solution-phase method. The corresponding bulky counterpart showed no photoresponse; however, a complete structural transformation toward a nanowire triggered activity for O₂ evolution in the presence of Ag⁺ as an electron acceptor under visible-light irradiation
