摘要：Photoactive nanowires play an important role on the photoelectric-relatedapplications; however, the in situ large-scale growth of photoactivenanowires on the arbitrary substrate still faces a great challenge.Herein, for the first time, we develop a facile coordination-inducedself-assembly strategy for preparing the nanowires with high photoactivitythrough keeping a high concentration of Sc(NO3)(3) and tartaric acid (TA) aqueous solution at room temperature. Surprisingly,the nanowires can grow directionally along the direction of waterflow on any substrate due to the growth mechanism driven by watermolecules, showing that the proposed nanowires are morphoplastic dependingon the direction of liquid flow. The formation of nanowires has beenproved to be attributed to the synergistic effect of water molecule-involvedhydrogen bonding between hydroxyl groups of TA ligands as well asthe multi-coordination of Sc3+ ions. Meanwhile, the preparednanowires are highly photoactive, showing a strong photooxidationability toward rhodamine 6G dyes, with a degradation efficiency ofabout 95.8% within 40 min. This finding introduces a coordinationgrowth mechanism of nanowires, which not only provides a great possibilityfor large-scale and low-cost synthesis of photoactive nanowires withmorphoplastic features but also shows a good application prospectin water cleaning by the photocatalysis technique.
