Supported σ-Complexes of Li−C Bonds from Coordination of Monomeric Molecules of LiCH3, LiCH2CH3 and LiC6H5 to Mo≣Mo Bonds
(German Chemical Society, 2022)
LiCH3 and LiCH2CH3 react with the complex [Mo2(H)2(μ-AdDipp2)2(thf)2] (1⋅thf) with coordination of two molecules of LiCH2R (R=H, CH3) and formation of complexes [Mo2{μ-HLi(thf)CH2R}2(AdDipp2)2], 5⋅LiCH3 and 5⋅LiCH2CH3, ...

Selective CO methanation with structured RuO2/Al2O3 catalysts
(Elsevier, 2018)
Active and selective structured RuO2/Al2O3 catalysts for CO methanation using a flow simulating CO2-rich reformate gases from WGS and PROX units (H2 excess, CO2 presence and 300 ppm CO concentration) were prepared. Both, ...

A direct in situ observation of water-enhanced proton conductivity of Eu-doped ZrO2: Effect on WGS reaction
(Elsevier, 2018)
Eu-doped ZrO2 solid solutions have been synthesized in order to prepare proton conductors as water-enhancer additives for the WGS reaction. Elemental characterization has been carried out revealing homogeneous ...

Pt/CePO4 catalysts for the WGS reaction: influence of the water-supplier role of the support on the catalytic performance
(Royal Society of Chemistry, 2018)
For Pt catalysts which have demonstrated great activity for the WGS reaction, the activation of water is described as the rate-limiting step. Such limitation could be overcome through the design of supports able to supply ...

Reversible carbon-boron bond formation at platinum centers through σ-BH complexes
(Royal Society of Chemistry, 2021)
A reversible carbon–boron bond formation has been observed in the reaction of the coordinatively unsaturated, cyclometalated, Pt(II) complex [Pt(ItBuiPr′)(ItBuiPr)][BArF], 1, with tricoordinated boranes HBR2. X-ray diffraction ...

Large-scale high-temperature solar energy storage using natural minerals
(Elsevier, 2017)
The present work is focused on thermochemical energy storage (TCES) in Concentrated Solar Power (CSP) plants by means of the Calcium-Looping (CaL) process using cheap, abundant and non-toxic natural carbonate minerals. CaL ...

Does shaping catalysts modify active phase sites? A comprehensive in situ FTIR spectroscopic study on the performance of a model Ru/Al2O3 catalyst for the CO methanation
(Elsevier, 2018)
Routinely, it seems assumed that the catalytic layer coated on monoliths and microchannel reactors preserve the properties of the initial powder catalyst. However, this assumption should be reasonably demonstrated since ...

Effect of starch as binder in carbon aerogel and carbon xerogel preparation
(Elsevier, 2019)
Carbon aerogels and carbon xerogels were synthesized through resorcinol – formaldehyde polycondensation using Na2CO3 as catalyst. The effect of soluble starch introduction in the organic gel preparation on the porous surface ...

Influence of gold particle size in Au/C catalysts for base-free oxidation of glucose
(Elsevier, 2017)
A series of gold colloids were prepared and immobilized on commercial activated carbon. The influence of the colloid preparation and stability were studied and related to the gold particle size in the final catalyst. The ...
