|Zeolites are a type of crystalline, microporous, silica-based structure with the ability to trap and contain individual atoms or ions. They often contain some fraction of their structural silicon atoms substituted for another atom; one of the most intriguing being tin. Tin containing zeolites known as stannosilicates, have a multitude of applications; however, they can be difficult to synthesize and produce unwanted byproducts of reaction.
Researchers at Purdue University have developed a method to synthesize stannosilicates with precisely controlled tin distributions and coordination. This is possible through the use of a liquid phase reflux to graft tin atoms into vacancies in the zeolite lattice. This method makes it possible to prepare tin zeolites with a wide range of tin content and densities up to four times higher than currently available synthesis routes. These carefully developed stannosilicates can be finely tuned to be used as a catalyst in a specific reaction, in ion-exchange, or adsorption applications.
