摘要 | Although there are many methods for preparing macroscopic nanomaterials, it is difficult to directly and completely maintain the structure from nanometer to macroscopic because of the insufficient structural strength. Here, large inorganic monolithic nanomaterials (LNMs) were directly synthesized by the complex nanostructure reinforced nanofilms self-regulating grown along with the bicontinuous emulsion (BE) interface in a threedimensional bicontinuous film (3DBF) rigid structure. The Zn(OH)(2)/SiO2 nanofilms have complex nanostructures divided into the nanofoam structure woven by Zn(OH)(2) nanoribbons in ionic bonds, and the silica aerogel cross-linked in covalent bonds, significantly strengthening the hard nanofilms. Therefore, the LNMs' structural strength is sufficient to directly overcome the surface tension and capillary pressure and completely maintain the structure from nanometer to macroscopic. Prepared with controllable shapes under mild condition, LNMs not only have the characteristics of traditional nanomaterials such as low density (0.0849 g mL(-1)) and high specific area (359.43 m(2) g(-1)), but also have new advantages such as high structural strength (compressive strength, 62555 Pa), low-shrinkage (2.97%), hierarchical pores (1 nm similar to >100 mu m), and high permeability. Moreover, the Zn(OH)(2)/SiO2 LNM columns (4 cm(3)) in a rigid hierarchical pore structure not only has the traditional catalytic and adsorption properties but also overcome fluid erosion and avoid the loss of nanoparticles, that the total Zn in the effluent without separation is 0.89 mg L-1. Therefore, this new method significantly facilitates the commercial synthesis and application of LNMs as convenient, safe, efficient, and stable components. |
