Abstract
Semiconductor nanowire where semiconducting characteristics as a bulk is confined to the magnitude of around 100 nm in two dimensions has merited special attention in terms of photocatalytic application. We report here self-organized methods that allow for large-scale synthesis of robust metal oxide nanowires and their performance as the heterogeneous photocatalysts. There will be a focus especially on a system of self-assembly between crystals. Specifically, a very slow supply of Mo6+ to the solution medium containing Ag+ by diffusion triggers particle growth through an oriented aggregation mechanism, which requires end-to-end and/or side-by-side structural accord between crystals, to allow for the first ever synthesis of monoclinic Ag2Mo2O7 nanowire whose stacked structure consists of asymmetrical edge- and corner-shared MoO6 chains. The nanowire possessed exceptional high crystallinity and showed activity for O2 evolution reaction from an aqueous AgNO3 solution under visible light irradiation.1 Considering the corresponding bulky counterpart shows no photoresponse, the complete structural transformation toward nanowire will be effective in engineering the heterogeneous photocatalysts.
