synthesis of ultralight iron oxide hierarchical structures with tailorable macro‐ and mesoporosity is reported. This method entails the growth of porous Prussian blue (PB) single crystals on the surface of a polyurethane sponge, followed by in situ thermal conversion of PB crystals into three‐dimensional mesoporous iron oxide (3DMI) architectures. Compared to previously reported ultralight materials,
据报道,一种合成具有轻度可调节的宏观和介孔性的超轻氧化铁分层结构的简便方法。此方法需要在聚氨酯海绵的表面上生长多孔普鲁士蓝(PB)单晶,然后将PB晶体原位热转化为三维介孔氧化铁(3DMI)结构。与以前报道的超轻材料相比,3DMI架构具有分层的宏观和中孔框架,具有多种优势,包括高表面积(约117 m 2 g -1)和超低密度(6-11 mg cm -3))。此外,它们可以以千克规模合成。更重要的是,这些3DMI结构具有超顺磁性和可调节的亲水性/疏水性,因此可以实现有效的多相界面吸附和快速的多相催化。
