Electroactive Nanoporous Metal Oxides and Chalcogenides by Chemical Design

摘要: The archetypal silica- and aluminosilicate-based zeolite-type materials are renowned for wide-ranging applications in heterogeneous catalysis, gas-separation ion-exchange. Their compositional space can be expanded to include nanoporous metal chalcogenides, exemplified by germanium tin sulfides selenides. By comparison with the properties of bulk dichalcogenides their 2D derivatives, these open-framework analogues may viewed as three-dimensional semiconductors filled nanometer voids. Applications exist a range molecule size shape discriminating devices. However, what is electronic structure chalcogenides? Herein, modeling used describe homologous series chalcogenides denoted np-MX2, where M = Si, Ge, Sn, Pb, X O, S, Se, Te, Sodalite, LTA aluminum chromium phosphate-1 types. Depending on choice anion tuned from insulators metals additional modification achieved through doping, solid solutions, inclusion (with fullerene, quantum dots, hole transport materials). These systems form basis new branch semiconductor nanochemistry three dimensions.
