A new template-free route to mesoporous ZSM-5 microspheres
Zeolites have been applied widely on catalytic processes because their intricate micropores provide different types of shape selectivity1. However, their small pore size brings diffusion and mass transfer limitations, which can be solved by using zeolite

The relation between the structure and magnetic properties of VO 2+ ( d 1 ) species and nitrosyl adducts of Cu + ( d 10 ) and Na + ( d o ) ions exchanged in the ZSM-5 zeolite was studied by DFT and EPR methods. Electronic g tensors were predicted using the spin-unrestricted zero order relativistic approximation (ZORA) and the scalar ...

Catalytic reduction of NO over in situ synthesized Ir/ZSM-5 monoliths
The catalytic performance of Ir-based catalysts was investigated for the reduction of NO under lean-burn conditions over binderless Ir/ZSM-5 monoliths, which were prepared by a vapor phase transport (VPT) technique. The catalytic activity was found to be

Optical Investigations of Intergrowth Effects in the Zeolite Catalysts ZSM-5 and ZSM-8
X-ray precession photographs and optical investigations of TPA-ZSM-5 (silicalite) and TEA-ZSM-8 zeolites reveal that ZSM-8 consists of two interpenetrating species rotated by 90° round the crystallographic c axis similarly to ZSM-5.

Cu-ZSM-5, Cu-ZSM-11, and Cu-ZSM-12 Catalysts for Direct NO Decomposition
Cu-ZSM-5 has for many years been recognized as a unique catalyst for direct NO decomposition. Here, it is discovered that both Cu-ZSM-11 and Cu-ZSM-12 are about twice as active as Cu-ZSM-5. This difference is attributed to the active sites located almost
