Catalysis & Zeolites
Zeolites and zeolite-like micro-porous materials have been playing an ever-increasing role in heterogeneous catalysis. Zeolites are the most important heterogeneous catalyst having huge industrial applications in fields like petrochemistry, petroleum refining, chemical synthesis & environmental protection. An important zeolite catalyst used in the petroleum industry is ZSM-5. Electron microscopic investigations of zeolites are reviewed.
