Soft‐Chemical Exfoliation Route to Layered Cobalt Oxide Monolayers and Its Application for Film Deposition and Nanoparticle Synthesis

“…One of the most effective methods to prepare 2D nanostructured materials is exfoliation: the separation of layered inorganic solids into individual layers through the intercalation of bulky organic molecules [5] or through the interlayer evolution of hydrogen gas by the hydroxylation of preintercalated lithium ions. [6] Many kinds of layered inorganic solids such as clays minerals, [7] graphites, [8] metal oxides, [9,10] metal hydroxides, [11] metal chalcogenides, [12] metal halides, [13] and metal phosphates [14] have been exfoliated into individual 2D nanosheets. Since most of the colloidal nanosheets obtained by the exfoliation route possess a considerable amount of surface charge, they can be used as building blocks for hierarchical superstructured materials in terms of electrostatic interaction.…”

Liquid Crystalline Nature of K4Nb6O17 Nanosheet Sols and Their Macroscopic Alignment

“…The exploitation of the semiconducting nature [4±6] and peculiar in-plane organization capability on the nanometer scale [39] of K 4 Nb 6 O 17 will lead to unusual materials, which cannot be derived from clays, etc. Exfoliation of layered niobates [10] and titanates [13] has recently been vigorously studied. Since these materials can also exhibit a liquid crystalline nature (e.g., we have recently found that the colloidal sol of [TiNbO 5 ] ± showed birefringence under flow), [40] studies with a series of these materials may lead to wide variety of advanced materials in the future.…”

Transforming MoO3 macrorods into bismuth molybdate nanoplates via the surfactant-assisted hydrothermal method

“…These bismuth materials with Aurivillius structures which have an intergrowth of [Bi 2 O 2 ] 2+ layers and [A m B m-1 O 3m+1 ] 2-perovskite-type sheets are one of the most appealing candidates for novel photocatalysts. Thus, the bismuth materials with layered structure have also attracted much attention for their admirable photocatalytic properties under the solar light [8,9]. Besides, bismuth molybdate materials with photocatalytic activity were reported in many papers [10][11][12].…”
