| abstract |
A stacked assembly of at least two layers having first and second surfaces, each layer comprising: a substantially two-dimensional array of crystal cells, each crystal cell having the empirical formula of Mn + 1Xn, such that each X is placed within an octahedral matrix of M; wherein M is at least one Group IIIB, IVB, VB, or VIB metal; each X is C, N, or a combination thereof; and n = 1, 2 or 3; wherein the layers are characterized by having an average surface area and a distance between layers; and wherein a kaolinitic intercalator is sandwiched between at least some of the layers, and wherein the kaolinitic intercalator is hydrazine, DMSO, urea, N, N-dimethylformamide, N-methylformamide (NMF), or 1-methyl-2-pyrrolidone ( NMP). |
