Improving the activity of gold nanoparticles for the water-gas shift reaction using TiO2–Y2O3: an example of catalyst design
(The Royal Society of Chemistry, 2018)
In the last ten years, there has been an acceleration in the pace at which new catalysts for the watergas shift reaction are designed and synthesized. Pt-based catalysts remain the best solution when only activity is ...

Ligand Effects in Carbon−Boron Coupling Processes Mediated by σ-BH Platinum Complexes
(Wiley, 2021)
The reaction of tri-coordinated boranes (derived from dioxaborolanes and diazaborolanes) with cyclometalated low-electron count platinum complexes [Pt(NHC’)(NHC)][BArF] (NHC=ItBuiPr, IMes, IMes*) led, at low temperature, ...

Rhodium and Iridium Complexes of Bulky Tertiary Phosphine Ligands. Searching for Isolable Cationic M(III) Alkylidenes
(American Chemical Society, 2015)
Cyclometalated chloride complexes of rhodium and iridium based on (5-C5Me5)M(III) fragments that result from the metalation of the xylyl substituent of a coordinated PR2(Xyl) phosphine (Xyl=2,6-Me2C6H3) have been prepared ...

Catalytic Upgrading of Biomass-Gasification Mixtures Using Ni-Fe/MgAl2O4 as a Bifunctional Catalyst
(American Chemical Society, 2022)
Biomass gasification streams typically contain a mixture of CO, H2, CH4, and CO2 as the majority components and frequently require conditioning for downstream processes. Herein, we investigate the catalytic upgrading of ...

Electronic structure of stoichiometric and Ar+-bombarded ZrO2 determined by resonant photoemission
(American Institute of Physics Publising LLC, 1995)
The electronic properties of thermally grown ZrO2 thin films before and after Ar+ bombardment have been studied with resonant photoemission spectroscopy using synchrotron radiation. For stoichiometric ZrO2 thin films the ...
