Reactions of layered perovskite-like oxides K2La2Ti3O10, NaLaTiO4 and corresponding protonated oxides H2La2Ti3O10, HLaTiO4 with vanadyl sulfate aqueous solution have been studied. It was revealed that the exchange reaction of interlayer alkali cations in K2La2Ti3O10 and NaLaTiO4 by with vanadyl cations, which was reported in the literature previously, does not proceed. The formation of the corresponding protonated forms and vanadium-containing particles is found to occur instead. In the case of protonated forms H2La2Ti3O10, HLaTiO4 vanadium-containing nanostructures are formed on the surface.

在层状钙钛矿状钛酸盐K 2 La 2 Ti 3 O 10和NaLaTiO 4的质子化形式表面上形成含钒的纳米结构

研究了层状钙钛矿型氧化物K 2 La 2 Ti 3 O 10,NaLaTiO 4和相应的质子化氧化物H 2 La 2 Ti 3 O 10,HLaTiO 4与硫酸氧钒的反应。结果表明,层间碱金属阳离子在K 2 La 2 Ti 3 O 10与NaLaTiO 4中的交换反应以前在文献中报道过的与钒基阳离子一起进行的方法没有进行。替代地发现了形成相应的质子化形式和含钒颗粒的形成。在质子化形式H 2 La 2 Ti 3 O 10的情况下,在表面上形成HLaTiO 4含钒的纳米结构。
