Protonated titanate nanotubes (HTiNTs) successfully catalyzed aldol condensation. This is due to the possession of strong acid sites (surface bridging OH groups). Polar solvents compete with substrates for active sites on the surface of HTiNTs. HTiNTs did not require any activation prior to the reaction. HTiNTs were reused several times and efficient even in a 1 g experiment.
