%X The TiO2-based nanotubes (TNTs, B每TNTs) of different surface acidities and their supported Rh catalysts were designed and synthesized. The catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectrometer (XPS), tempera每ture每programmed desorption of ammonia (NH3每TPD), atomic emission spectrometer (ICP), and Brunauer每Emmett每Tellerv (BET) surface-area analyzers. Images of SEM and TEM showed that the boron-decorated TiO2 nanotubes (B每TNTs) had a perfect multiwalled tubular structure; their length was up to hundreds of nanometers and inner diameter was about 7 nm. The results of NH3-TPD analyses showed that B每TNTs had a stronger acid site compared with TNTs. For Rh/TNTs and Rh/B每TNTs, Rh nanoparticles highly dispersed on B每TNTs were about 2.79 nm in average diameter and much smaller than those on TNTs, which were about 4.94 nm. The catalytic performances of catalysts for the hydroformylation of 2-methyl-3-butennitrile (2M3BN) were also evaluated, and results showed that the existence of B in Rh/B每TNTs had a great influence on the catalytic performance of the catalysts. The Rh/B每TNTs displayed higher catalytic activity, selectivity for aldehydes, and stability than the Rh/TNTs
