Novel methods for synthesis of zeolites and zeolite-encapsulated metal particles

Zeolites are unknown to many even though they have a large impact on our daily life. Zeolites and zeolites with active metals are used in the oil industry to make fuel for cars but they are also used for purification of the exhaust gas by removing harmful gasses.

There is an ongoing development of zeolites and zeolites with catalytically active metal particles to continuously deal with new challenges and to improve the already existing technologies. Yet, there is no general way to obtain these materials and many of the ways to make them produces a lot of waste.

In this dissertation, different ways to make zeolites were examined with a special focus on minimizing the environmental impact from the production. These production methods were also used to integrate active metals in the zeolite material to obtain materials active for catalysis.

Several types of zeolites were made by different manufacturing methods which avoided the use of different polluting chemicals. Direct implementation of the metals in the manufacturing was accomplished and the materials showed activity for oxidation of toxic carbon monoxide and were selective for hydrogenation of different molecules.

Overall, new methods to make zeolites were developed and metal particles could be integrated in the process to obtain catalytically active materials.
