The Use of Palygorskite as a Catalytic Support for TiO2 on the Degradation of Herbicide: A Review

The immobilization of catalyzers is an alternative to aid the process of photocatalysis. The clays are compounds of high porosity and abundant in nature, therefore, this work aimed at carrying out a prospective study of the use of palygorskite as catalytic support for TiO2 on the degradation of the bentazone herbicide. The bibliographic search on the database (Scopus, Web of Science and SciELO) and patent base (EPO, USPTO and INPI). The results showed that the published articles address the synthesis with excellent results on the degradation of different pollutants. With regard to the patents, it could be observed that some palygorskite-based materials have already been patented. The results show that palygorskite is an excellent alternative for obtaining materials with photocatalystic activity.
