The use of catalysis in the chemical industry is known in procedures for preparing a wide range of chemical products. Among the different types of catalysis that exist, heterogeneous catalysis has many advantages, such as an easier separation of the catalyst after the reaction, to the advantage of recycling it. Often the catalyst is in solid phase, which allows to increase the number of process options and to reduce the pollutant discharges of the process, while the reagents are in liquid phase.

New composite material based on Titania and Aquivion or PFSA with use as a catalyst precursor or support


  • structure with good surface area and porosity
  • excellent acid catalytic activity in reaction in the gas phase


Possible applications:

In the chemical industry,

  • to dehydrate alcohols such as, in particular, ethanol;
  • to obtain ethylene.
