ZSM-35 is a type of synthetic zeolite, which belongs to the family of molecular sieves. It has a unique framework structure known as FER (named after the mineral ferrierite), which gives it specific properties that make it useful in various catalytic applications. Here's an overview of ZSM-35 molecular sieve:
Key Features and Properties
-
Structure: The FER structure of ZSM-35 consists of intersecting 8-membered ring channels, with pore openings measuring approximately 0.35 x 0.48 nm.
-
Acidity: ZSM-35 can be synthesized with varying levels of acid sites, which are crucial for its catalytic performance.
-
Thermal Stability: It exhibits good thermal stability, allowing it to maintain its structure and functionality at high temperatures.
