The incorporation of carbon into the carbon monoxide and cyanide ligands of [NiFe]-hydrogenases has been investigated by using (13)C labelling in infrared studies of the Allochromatium vinosum enzyme and by (14)C labelling experiments with overproduced Hyp ...
The following chapter summarizes the various methodologies allowing the reductive cleavage of various carbon---hetereroatom single bonds or multiple bonds naming the transformation of C---N bond, C---P, C---As, C---Sb, C---Bi, C---C, C---Si, C---Ge, C---B, ...
A novel composite material based on carbon nanofibers (CNF) grown on sintered metal fibers (SMFInconel) filter was investigated for its favorable properties as catalytic support. The CNF were formed directly over the SMFInconel by thermal (650 degrees C) c ...
The dynamics of N2O decompn. to gaseous nitrogen and oxygen over HZSM-5 catalysts with a low iron content (200 and 1000 ppm) was studied by the transient response. Method in the temp. range 523-653 K. The active catalysts were prepd. from HZSM-5 with Fe in ...
Gold nanoparticles were supported on activated carbon fibers (ACF) using the aq. soln. of [Au(en)2]Cl3 via ion-exchange with surface hydroxyl groups followed by redn. in H2. The obtained catalysts were tested in CO oxidn. at room temp. Surface phenolic gro ...
Pure and K-doped vanadia/titania catalysts have been studied by transient response method and in situ DRIFTS during toluene partial oxidn. They were characterized by FT-Raman spectroscopy, TPR, TPD of pyridine and XPS. In order to elucidate the role of dif ...
The role was studied, of bulk V2O5 in vanadia/titania catalysts in partial oxidn. of toluene. Two catalysts with 1.8 and 11.1% of V were studied, by in situ DRIFTS and transient-response methods. Bulk V2O5 was found by FT-Raman spectroscopy only in the 11. ...
Syntheses of thermally stable chromium-incorporating hexagonal mesoporous aluminophosphate and cubic Cr-MCM-48 were reported. Characterization of the catalysts was made using low angle XRD, N2 adsorption, UV-VISDRS, thermal anal., ICP-AES and ESR. Mesoporo ...
FeZSM-5 with a wide range of Fe content (0.015–2.1 wt%) were studied in the benzene hydroxylation to phenol with nitrous oxide (C6H6:N2O = 1:5) at low temperatures (
