Selective Hydrogenation of C=C bond in Cinnamaldehyde on Pd Step Sites of Pd/Al2O3

Autor: Junya Ohyama, Takumi Shiotani, Kazumasa Murata, Atsushi Satsuma

Publikováno v: Chemistry Letters. 50:599-602

We found a positive correlation between C=C selective hydrogenation activity of cinnamaldehyde (CAL) and the fraction of the Pd step site on Pd nanoparticles. Owing to a high fraction of step sites...

Kinetic analysis of Ag particle redispersion into ZSM-5 in the presence of coke using in situ XAFS

Autor: Kazumasa Murata, Atsushi Satsuma, Junya Ohyama

Publikováno v: Catalysis Science & Technology. 11:506-515

In the present study, the redispersion behavior of Ag particles on ZSM-5 in the presence of coke was observed using in situ X-ray absorption fine structure (XAFS) spectroscopy. The dynamics of Ag particle redispersion into the ZSM-5 pores were evalua
