Effect of WO3 Content in WO3-ZrO2-P Catalysts on the Catalytic Pathways of Glycerol Transformation

What is it about?

Changing the content of tungsten oxide in phosphate-stabilized WOx-ZrO2 catalysts dramatically changes the direction of the glycerol transformation. Catalysts with a low WOx content are selective for allyl alcohol formation due to Lewis sites Zr4+ and W6+. Increasing WOx concentration leads to the appearance of Brønsted acid sites, contributing to acrolein formation

Why is it important?

The results obtained hint at the design of new effective catalysts for the production of valuable chemicals by glycerol processing, a byproduct of biodiesel production.
