Congratulations to Dr. Kachaporn Saenluang, postdoctoral researcher from the School of Energy Science and Engineering (ESE) under the supervision of Assoc. Prof. Dr. Chularat Wattanakit, for the recent article in Catalysis Science & Technology.
Topic: Cu encapsulated in hierarchical MFI zeolites for ethanol dehydrogenation to acetaldehyde
This article report the design of the Cu nanoparticles encapsulated within both hierarchical and conventional MFI frameworks for the ethanol dehydrogenation. The results showed that the hierarchical silicalite-1 zeolite (Cu@hieS-1) exhibited the simultaneous presence of mesopores and uniformly Cu nanoparticles, with high Cu dispersion, thereby significantly improving active-site accessibility and reducing diffusion path lengths. Catalytic testing demonstrated that the Cu@hieS-1 achieved 96% ethanol conversion and 82% acetaldehyde, outperforming conventional zeolites. This work illustrates the benefits of the encapsulated catalyst in optimizing catalytic performances for sustainable acetaldehyde production.
