Enhancement of the ETS-10 titanosilicate activity in the shape-selective photocatalytic degradation of large aromatic molecules by controlled defect production

Mild postsynthesis treatments of ETS-10 molecular sieves with diluted HF/water solutions are found to be a convenient method to enhance surface reactivity, as compared to that of the as-synthesized material. Mild conditions like diluted acid solutions and short contact times have to be adopted to prevent the crystal structure of the solid from collapsing.
