- •
The use of TS-1 for the oxidation of furfural to maleic acid with H2O2 is reported.
- •
Extraframework TiO2 nanodomains can also be located in the channels and cavities of TS-1.
- •
When present, it blocks the access of reactants to active sites.
- •
Coke deposition and Ti leaching are identified as the main causes of deactivation.
