单晶过渡金属钨酸盐纳米棒/纳米线的一般大规模合成可以通过水热结晶技术在温和条件下使用廉价和简单的无机盐作为前体轻松实现。通过水热转化和非晶颗粒的重结晶可以容易地获得均匀的钨酸盐纳米棒/纳米线，例如MWO 4（M = Zn，Mn，Fe），Bi 2 WO 6，Ag 2 WO 4和Ag 2 W2 O 7，其直径为20-40 nm，长度高达微米，并且纵横比可控。这种在温和条件下制备各种相关低维钨酸盐纳米晶体的新颖而有效的途径可以为进一步研究钨酸盐材料的新特性开辟新的机会。
The general large‐scale synthesis of a family of single‐crystalline transition metal tungstate nanorods/nanowires is easily realized by a hydrothermal crystallization technique under mild conditions using cheap and simple inorganic salts as precursors. Uniform tungstate nanorods/nanowires such as MWO4 (M = Zn, Mn, Fe), Bi2WO6, Ag2WO4, and Ag2W2O7 with diameters of 20–40 nm, lengths of up to micrometers, and controlled aspect ratios can be readily obtained by hydrothermal transformation and recrystallization of amorphous particulates. This novel and efficient pathway toward various kinds of related low‐dimensional tungstate nanocrystals under mild conditions could open new opportunities for further investigating the novel properties of tungstate materials.
