| 英文摘要 | despite the significant progress in making hollow structures, it is still a challenge to synthesize some specialized hollow structures. in the present work, we obtained a new hollow hematite structure, tube-in-dodecahedron, by using the stepwise influences of fluoride and phosphate anions. based on condition-dependent experiments, we proposed a "nucleation-aggregation-recrystallition and etching" mechanism, which also directed us to synthesize a series of hematite hollow structures, including hollow dodecahedron and hollow ellipsoid. the concentration of phosphate was found to play a decisive role in the control of these hollow structures. 0.08 mm is the critical point for keeping the top facets of dodecahedral hematite particles while 0.2 mm is the upper limit for keeping the lateral facets. the magnetic properties of these synthesized hollow hematite structures were found to be closely associated with the structures. the synthesized tube-in-dodecahedral hematite particles exhibited excellent photocatalytic reactivity toward organic dyes. |
