Lithium Di-‐ and Trimethyl Dimolybdenum(II) Complexes with Mo-‐Mo Quadruple Bonds and Bridging Methyl Groups
(American Chemical Society, 2015)
New dimolybdenum complexes of composition [Mo2{μ-Me}2Li(S)}(μ- X)(μ-N^N)2] (3a−3c), where S = THF or Et2O and N^N represents a bidentate aminopyridinate or amidinate ligand that bridges the quadruply bonded molybdenum ...

A new model of the carbonator reactor in the Calcium Looping technology for post-combustion CO2 capture
(Elsevier, 2015)
The Ca-Looping (CaL) process is considered as a promising technology for CO2 post-combustion capture in power generation plants yielding a minor penalty on plant performance as compared with other capture technologies ...

A Diels–Alder Reaction Triggered by a [4 + 3] Metallacycloaddition
(American Chemical Society, 2015)
The TpMe2Ir(III) complex 1-OH2 (TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate), which contains a labile molecule of water and an iridium-bonded alkenyl moiety (−C(R)═C(R)–(R=CO2Me)) as part of a benzo-annulated five-membered ...

Free-Base Carboxyphenyl Porphyrin Films Using a TiO2 Columnar Matrix: Characterization and Application as NO2 Sensors
(Multidisciplinary Digital Publishing Institute (MDPI), 2015)
The anchoring effect on free-base carboxyphenyl porphyrin films using TiO2 microstructured columns as a host matrix and its influence on NO2 sensing have been studied in this work. Three porphyrins have been used: ...

Synthesis and structure of mixed carboxylate-aminopyridinate and -amidinate complexes of dimolybdenum and ditungsten
(Elsevier, 2015)
We describe in this paper the synthesis and structural characterization of dimolybdenum and ditungsten complexes with MM bonds derived from the metal–metal bonded tetracarboxylates [M2(O2CR)4] and incorporating one or two ...

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 ...

Ni-CeO2/C Catalysts with Enhanced OSC for the WGS Reaction
(MDPI AG, 2015)
In this work, the WGS performance of a conventional Ni/CeO2 bulk catalyst is compared to that of a carbon-supported Ni-CeO2 catalyst. The carbon-supported sample resulted to be much more active than the bulk one. The higher ...

Limestone calcination nearby equilibrium: Kinetics, CaO crystal structure, sintering and reactivity
(American Chemical Society, 2015)
In this work, we analyze limestone calcination kinetics at environmental conditions involving a CO2 partial pressure P close to the equilibrium pressure Peq by means of in situ X-ray diffraction (XRD) and thermogravimetric ...

Mono and bimetallic Cu-Ni structured catalysts for the water gas shift reaction
(Elsevier, 2015)
The water-gas shift (WGS) reaction over structured Cu, Ni, and bimetallic Cu-Ni supported on active carbon (AC) catalysts was investigated. The structured catalysts were prepared in pellets form and applied in the medium ...

Simultaneous production of CH4 and H2 from photocatalytic reforming of glucose aqueous solution on sulfated Pd-TiO2 catalysts
(EDP Open, 2015)
In this work, the simultaneous production of CH4 and H2 from photocatalytic reforming of glucose aqueous solution on Pd-TiO2 catalysts under UV light irradiation by Light-Emitting Diodes (LED) was investigated. The Pd-TiO2 ...
