abstract = {Inorganic–organic hybrid WOx-ethylenediamine (WOx–EDA) nanowires have been produced by a simple, low-cost and high-yield solvothermal method. These WOx–EDA hybrid nanowires have unique lamellar mesostructures with an alternate stacking of an interconnected [WO6] octahedral layer and a monolayer of ethylenediamine molecules. This hybrid structure integrated the functionality of ethylenediamine with the stability of the WOx frameworks. In situ synchrotron-radiation X-ray diffraction is used to elucidate a possible formation mechanism of the hybrid WOx–EDA. The nanowire morphology, lamellar structure and abundant functional amino groups endow them with versatile abilities. For example, in heavy metal ion adsorption the WOx–EDA nanowires display exceptional adsorption capabilities of 925 mg·g–1 for Pb2+ and 610 mg·g–1 for UO22+. The nanowires also show outstanding stability and activity as a heterogeneous base catalyst in the Knoevenagel condensation reaction at room temperature. The catalyst can be recycled and reused for 20 cycles with nearly 100% yields. This study provides a new strategy to design inorganic–organic hybrid materials, and offers a multifunctional material that is a highly efficient adsorbent and sustainable catalyst.}
