Synthesis of HZSM-5 coatings on the inner surface of stainless steel tubes and their catalytic performance in n-dodecane cracking

- The thickness of HZSM-5 layers can be manipulated by changing the growth time.
- Synergy between thickness and diffusivity of HZSM-5 layer determines ZSR performance.
- A non-compact microstructure is necessary for catalytically active zeolite coatings.
