摘要: Abstract One-dimensional protonated titanate nanostructures were tested as solid acid catalysts in the condensation reaction between benzaldehyde and cyclohexanone. Two morphologies employed – nanotubes nanoribbons. In situ diffuse reflectance infrared Fourier transform spectroscopy of adsorbed NH 3 temperature programmed desorption revealed that both nanoribbons possess Lewis Bronsted sites with medium strength, whereas only have also strong sites. Therefore an efficient catalyst was successfully applied to other systems substituted derivatives. Recycling studies showed no significant decrease catalytic activity five cycles even excellent performance large scale experiment. addition, did not require any activation prior reaction. The mechanism is proposed describe process over catalyst.
