The Calcium-Looping technology for CO2 capture: On the important roles of energy integration and sorbent behavior
(Elsevier, 2016)
The Calcium Looping (CaL) technology, based on the multicyclic carbonation/calcination of CaO in gas–solid fluidized bed reactors at high temperature, has emerged in the last years as a potentially low cost technology for ...

Monomeric alkoxide and alkylcarbonate complexes of nickel and palladium stabilized with the iPrPCP pincer ligand: a model for the catalytic carboxylation of alcohols to alkyl carbonates
(Royal Society of Chemistry, 2019)
Monomeric alkoxo complexes of the type [(iPrPCP)M-OR] (M = Ni or Pd; R = Me, Et, CH2CH2OH; iPrPCP = 2,6-bis(diisopropylphosphino)phenyl) react rapidly with CO2 to afford the corresponding alkylcarbonates [(iPrPCP)M-OCOOR]. ...

Operando DRIFTS-MS Study of WGS and rWGS Reaction on Biochar-Based Pt Catalysts: The Promotional Effect of Na
(MDPI, 2018)
Biochar-based Pt catalysts, unpromoted and Na-promoted, were prepared by an incipient wetness impregnation method and characterised by Inductively coupled plasma mass spoectrometry (ICP-MS) analysis, X-ray diffraction, N2 ...

Tailoring structured WGS catalysts: Impact of multilayered concept on the water surface interactions
(Elsevier, 2018)
A novel multilayer approach for designing structured WGS catalyst is employed in this study as a response to the lack of new strategies in the literature. The approach proposes the use of two successive layers with ...

Colombian metallurgical coke as catalysts support of the direct coal liquefaction
(Elsevier, 2019)
A Colombian metallurgical coke was modified in its surface chemistry and was used as support of iron sulfide catalysts for direct coal liquefaction. The modification was made by treatments with diluted oxygen and HNO3 at ...

σ-Silane Platinum(II) Complexes as Intermediates in C−Si Bond-Coupling Processes
(Wiley, 2019)
Platinum complexes [Pt(NHC’)(NHC)][BArF] (NHC’ denotes the cyclometallated N-heterocyclic carbene ligand, NHC) react with primary silanes RSiH3 leading to the cyclometallated platinum(II) silyl complexes [Pt(NHC-SiHR’ ...

Effect of the crystal chemistry on the hydration mechanism of swelling micas
(Elsevier, 2017)
Swelling and dehydration under minor changes in temperature and water vapor pressure is an important property that clays and clay minerals exhibit. In particular, their interlayer space, the solid-water interface and the ...

Electrical properties of bismuth ferrites: Bi2Fe4O9 and Bi25FeO39
(Elsevier, 2019)
Bi2Fe4O9 was prepared by solid-state reaction and the electrical properties measured by impedance spectro- scopy. After annealing in O2 at 900 °C, Bi2Fe4O9 is an electrically-homogeneous insulator. Its high frequency p ...
