Synthesis of well-defined allophane nanospheres
Well-defined allophane nanospheres, with internal and external diameters of 3.0 and 3.9 nm, respectively, were successfully synthesized and characterized by cryo-TEM, SAXS, and IR spectroscopy. In addition, we propose a refined structural framework, clarifying the coexistence of open and closed imogolite- local structures, which are commonly grouped together under the term allophane .
