What is it about?
Only the samples based on sulfated titania are active over glycerol conversion. Glycerides up to pentaglycerides, linear and nonlinear structures are formed over TiO2-S. Addition of nanotubes increases the selectivity for short-chain glycerides. Herewith, glycerides of a linear structure only formed

Why is it important?
The catalytic materials based on titanium dioxide show unexpectedly good performance for the glycerol oligomerization. Although individual titania is inactive in the oligomerization of glycerol, modification of TiO2 with sulfonic groups causes the appearance of catalytic activity with the formation of a wide range of polyglycerides. Fabrication of a composite of sulfated titania with carbon nanotubes results in an increase in the selectivity for polyglycerides and simultaneously limits the range of oligomerization products with short-chain glycerides of linear structure.
Perspectives
The paper shows that the modification of titanium oxide by both sulfonic groups and carbon nanotubes gives a promising way for fabrication of a selective catalyst for the oligomerization of glycerol producing short-chain polyglycerides.
