A Single‐Crystalline Mesoporous Quartz Superlattice

Abstract: There has been significant interest in the crystallization of nanostructured silica into a-quartz because of its physicochemical properties.W ed emonstrate as ingle-crystalline mesoporous quartz superlattice,asilica polymorph with unprecedentedly ordered hierarchical structures on both the several tens of nanometers scale and the atomic one.T he mesoporous quartz superlattice consists of periodically arranged a-quartz nanospheres whose crystalline axes are mostly oriented in an assembly.The superlattice is pre… Show more

“…The surfactant is still present after microwave treatment, which may allow delicate mesostructuration to be preserved, as has been beneficial in creating mesostructured quartz. 34 However, if the surfactant must be removed, it is possible to do so by refluxing in a mildly acidic solution of ethanol for 1 h (Figure S3). This protocol efficiently removed octadecyl amine from the titania spheres, without visibly damaging their structure or the degree of crystallinity.…”

“…There are only scarce reports available about singlecrystalline mesoporous oxides or nitrides in literatures. [14][15][16][17][18][19][20][21][22][23] The preparation of single-crystalline mesoporous metals is even more challenging since metals generally have larger surface energy than oxides, and have a greater propensity to minimize their surface areas and form disordered structures. 20,24,25 This synthetic obstacle largely precludes their potential applications at the current stage.…”
