Esterification process catalyzed by ZSM-5 zeolite synthesized via modified hydrothermal method
MethodsX, 2018 A modified hydrothermal method for ZSM-5 synthesis was described. The crystals gave a typical pattern (2θ at around 22.5°, 24.0° and 29.8° corresponding to the major peaks of (501, 303 and 503 crystal surfaces)), which indicated that the subnanocrystals ...

Cu‐ERI Zeolite Catalysts With Tailored Properties for the Removal of N‐Containing Compounds
Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.The study found that Cu‐ERI zeolites, especially Cu‐ERI_2, show strong low‐temperature NH3‐SCR‐DeNOx activity and high N2 selectivity because they contain highly active, easily reducible Cu2+ species; Cu‐ERI_2 also facilitates NH3 activation and preferentially consumes NH3 adsorbed on Brønsted acid sites during NO reduction.

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.Enhanced hydrogen species migration enabled by FN/BZY catalyst mitigates intermediate accumulation and improves DA‐PCFC performance during ammonia decomposition. Ammonia, with its high hydrogen density and carbon‐free nature, serves as ideal fuel for direct ammonia protonic ceramic fuel cells (DA‐PCFCs).

Butene catalytic cracking to propene and ethene over potassium modified ZSM-5 catalysts
, 2005 Catalytic cracking of butene over potassium modified ZSM-5 catalysts was carried out in a fixed-bed microreactor. By increasing the K loading on the ZSM-5, butene conversion and ethene selectivity decreased almost linearly, while propene selectivity ...
