Boosting TS-1 Zeolite: Titanium Hack Unveiled
TS-1 zeolite has long been recognized as a game-changer in selective oxidation catalysis, especially for environmentally friendly processes using hydrogen peroxide. However, conventional TS-1 often suffers from limited titanium accessibility, which restricts its catalytic efficiency. Recent research has revealed a clever “titanium hack” that significantly boosts TS-1 performance by improving the dispersion and coordination environment of titanium species within the zeolite framework. The key to this enhancement lies in controlling how titanium is incorporated during synthesis. By fine-tuning the titanium precursor, pH conditions, and crystallization parameters, scientists can ensure that titanium is predominantly present as isolated tetrahedral Ti sites rather than inactive TiO₂ clusters. These isolated Ti sites are highly active and selective, directly responsible for superior oxidation performance in reactions such as epoxidation and hydroxylation.
