Interplay of the PtsN (EIIANtr) protein of Pseudomonas putida with its target sensor kinase KdpD
(2015-08-27)
The nitrogen phosphotransferase system (PTSNtr) of Pseudomonas putida is a multi-component regulatory device that participates in controlling a variety of physiological processes in a post-translational fashion. A general ...

Bimetallic PtSn catalyst for the selective hydrogenation of furfural to furfuryl alcohol in liquid phase
(Elsevier Science, 2009-05-20)
Bimetallic PtSn catalysts, containing different amounts of tin, were obtained by means of controlled surface reactions and used in the liquid-phase hydrogenation of furfural. All the studied systems allowed to obtain fufuryl ...
Pt, PtSn and PtGe catalysts supported on granular carbon for fine chemistry hydrogenation reactions
(Elsevier Science, 2008-04)
Two series of PtSn and PtGe catalysts with different metallic loadings, supported on activated carbon powder, were prepared by successive impregnation. Both the effects of the second metal addition and the Sn or Ge loading ...
Effect of particle size in the hydrogenation of crotonaldehyde on supported Pt and Pt-Sn catalysts
(Springer, 2002-03)
The present work reports the effect of metal particle size on the selectivity to crotyl alcohol (SUOL) in the liquid phase hydrogenation of crotonaldehyde over SiO2 and α-Al2O3-supported Pt and Pt-Sn catalysts. It was ...
Asymmetric hydrogenation of 3,4-hexanedione over PtSn catalysts
(Springer, 2010-05-22)
In this work, some results of the liquid-phase racemic and enantioselective hydrogenation of 3,4-hexanedione are presented. The catalysts employed were platinum-based, supported on SiO2. Monometallic catalysts were modified ...
n-Decane dehydrogenation on Pt, PtSn and PtGe supported on spinels prepared by different methods of synthesis
(Elsevier, 2013-07)
The catalytic performance of Pt, PtSn and PtGe supported on ZnAl2O4 obtained by mechanochemical synthesis (MS) or coprecipitation (COPR) is studied in the production of 1-decene from the n-decane dehydrogenation. The effect ...
Silica-supported PtSn catalysts obtained through surface organometallic chemistry on metals techniques using a hydrosoluble organotin promoter. Application to the selective hydrogenation of α,β-unsaturated aldehydes and ketones
(Bentham Science Publishers, 2014-03)
In this paper we propose the preparation of a PtSn bimetallic catalyst through techniques derived from Surface Organometallic Chemistry on Metals (SOMC/M) using water as solvent. The system, PtSn0.2ac, was employed in the ...
