Title
Nanotubular TiO2-supported amorphous Co–B catalysts and their catalytic performances for hydroformylation of cyclohexene
Abstract

•The nano-confinement effect of multiwall TNTs was utilized for preparing Co–B/TNTs.•Co–B deposited on the surface of TNT and entered into the interspace between walls.•Co–B/TNTs showed high catalytic activity and stability for hydroformylation.•The leaching of catalytically active species from Co–B/TNTs was very small.

TiO2 nanotubes supported amorphous Co–B catalysts (Co–B/TNTs) were prepared via WI-CRP. The catalysts were characterized with TEM, XPS, TPD, nitrogen adsorption and so on. The catalytic performances and stabilities of Co–B/TNTs for hydroformylation of cyclohexene as well as the influence factors, such as reaction media and Co loading, were investigated. The Co–B/TNTs not only exhibited better catalytic performances in ether than in acetone and alcohol, but also showed higher activities and stabilities than TiO2 powder supported amorphous Co–B under the same reaction conditions. The reuse of Co–B/TNTs was also tested, and the results showed that the used catalysts maintained high catalytic activity.
