以不同二氧化钛为原料,用水热法制备一维钛酸盐纳米材料.原料一次粒径和晶体结构对一维纳米钛酸盐的形貌和结构的影响很大.原料的一次粒径越小,反应过程中产物的形貌和晶相转变越快:纯锐钛矿相有利于钛酸盐纳米管的形成,而少量金红石相则有利于纳米管向纳米线的进一步转变和晶相转变.

One-dimensional titanate nanomaterials were synthesized by a hydrothermal reaction using different titania sources.The morphology and crystal structure of the one-dimensional titanate nanomaterials were greatly affected by the primary particle size and crystal structure of the starting materials.The smaller initial particle size of the reactant led to a faster phase transformation of the products.The pure anatase titania favored the formation of titanate nanotubes,while the mixture of anatase titania and a small amount of rutile titania as a starting material favored the further transformation of nanotubes to nanowires or nanoribbons and promoted the phase transformation.
