Synthesis of novel copper sulfide hollow spheres generated from copper (II)–thiourea complex

Hollow Micro‐/Nanostructures: Synthesis and Applications

“…Recently, chains of Co hollow sub-microspheres have been synthesized via aggregation of PVP-stabilized primary nanoparticles presumably assisted by the gas bubbles liberated from the reaction. [255] Gas bubble templating has also been suggested as a means for preparing hollow spheres of sulfides (ZnS, [256] CuS [257] ), oxides (SnO 2 , [258] TiO 2 , [259] Fe 3 O 4 [260] ). It should be pointed out that the gas bubble templating mechanism remains highly speculative, especially in systems involving highly soluble gases (CO 2 , NH 3 ) resulting from decomposition of organic molecules such as urea and thiourea.…”

“…It should be pointed out that the gas bubble templating mechanism remains highly speculative, especially in systems involving highly soluble gases (CO 2 , NH 3 ) resulting from decomposition of organic molecules such as urea and thiourea. [257,258,260] Another special type of gas bubble templating is utilized in sonochemical synthesis of hollow particles, where the gas bubbles generated from the collapse of the acoustic cavitation [261] are generally believed to serve as the soft templates for shell formation. [101] It has been suggested that cavitation microbubbles created by sonication of a surfactant-containing medium are particularly advantageous because they can be stabilized in a similar manner to normal liquid-liquid emulsions.…”

Synthesis, conversion and comparison of the photocatalytic and electrochemical properties of ZnSe·N2H4 and ZnSe microrods

“…Also, they can be used as precursors for preparation of some semiconductors such as ZnS [3,4], ZnO [3][4][5][6][7], CdSe [8], ZnSe [9][10][11][12], CuS [13] and Cu 2 S [14] via thermal decomposition, hydrothermal or solvothermal process, solid-state reaction and so on. Usually, some organic substances containing N atoms such as ethylenediamine (en) are apt to coordinate with metal ions, especially transition metal ions, and can be used as structure-directing reagents during the syntheses of some semiconductors [15][16][17].…”

Well‐Defined Non‐spherical Copper Sulfide Mesocages with Single‐Crystalline Shells by Shape‐Controlled Cu2O Crystal Templating

“…[34][35][36][37][38][39] Hollow spheres of copper sulfide have also been successfully produced by employing soft sacrificial templates or the self-assembly route. [14,[40][41][42] However, to the best of the authors knowledge, there has been no report on the synthesis of non-spherical copper sulfide mesocages with single-crystalline shells. Herein, a template-assisted synthesis of well-defined non-spherical Cu x S mesocages by using shape-controlled Cu 2 O crystals as sacrificial templates is reported.…”
