文摘

We have reported the synthesis of superstructured nanonetworks of BiOCl and nested nanonetworks of Bi₂S₃ in a series of lattice-directed topotactic transformations [C. F. Guo et al. J. Am. Chem. Soc.2011, 138, 8211鈥?215]. Here we extend the transformations to a much broader system including ordered nanowall networks of BiOCl, BiOBr, Bi₂O₂CO₃, 尾-Bi₂O₃, and Bi₂S₃, as well as nested self-similar networks of Bi₂S₃ and amorphous BiO_x. We suggest even more superstructured networks and nested self-similar networks of bismuth compounds with a lattice parameter of 2^n/2 脳 3.9 脜 (n = 0, 1, 2, 3, 4), might also be obtained. The superstructured networks and nested networks are novel architectures that may find applications in electronic devices, sensors, filters, and photocatalysts.
