Synthesis of titanate nanotube solid acid catalysts and C-C bond formation reaction

在不同条件下合成了质子化钛酸盐纳米管，并对其进行了杂原子掺杂改性。这些催化剂被用于C-C键的形成反应。根据合成条件的不同，将纳米二氧化钛转化为钛酸盐纳米管或纳米棒，有效的Bronsted和Lewis酸中心仅在钛酸盐纳米管的表面形成。此外，当Nb5+和Ta5+离子掺杂到钛酸盐纳米管中时，催化性能提高了10倍。

Protonated titanate nanotubes were synthesized under various conditions and modified by doping with heteroatoms. These catalysts were applied for C-C bond formation reactions. TiO2 nanoparticles were converted into titanate nanotubes or nanorods depending on the synthesis conditions and effective Bronsted and Lewis acid sites were only formed on thesurface of the titanate nanotubes. In addition, when Nb5+ and Ta5+ ions were doped into the titanate nanotubes, the catalytic performance was enhanced by a factor of 10.
