El inicio de la Química Organometálica moderna data de 1952 con la elucidación de la estructura tipo sándwich del ferroceno por los laboratorios de Wilkinson y de Fisher, de forma independiente. Este hito se toma como el punto de partida desde el cual, la Química Organometálica se ha desarrollado de manera exponencial y ha permeado de manera...

The use of the exceptionally bulky tris-2-(4,40 -di-tert-butylbiphenylyl) phosphine ligand allows the isolation and complete characterization of the first dicoordinate gold(I)–ethylene adduct, filling a missing fundamental piece on the organometallic chemistry of gold. Besides, the bonding situation of this species has been investigated by...

The multicycle CO capture performance of CaO derived from natural limestone and dolomite has been investigated by means of thermogravimetry under realistic Calcium-Looping conditions, which necessarily involve high CO concentration and high temperatures in the calcination stage and fast transitions between the carbonation and calcination...

Organometallic gold complexes are used in a range of catalytic reactions, and they often serve as catalyst precursors that mediate C–C bond formation. In this study, we investigate C–C coupling to form ethane from various phosphine-ligated gem-digold(I) methyl complexes including [Au2(μ-CH3)(PMe2Ar′)2][NTf2], [Au2(μ-CH3)(XPhos)2][NTf2], and...

In this study, CaO derived from steel slag pretreated with diluted acetic acid has been tested as a dry sorbent for CO capture under realistic Ca-Looping (CaL) conditions, which necessarily implies calcination under high CO partial pressure and fast transitions between carbonation and calcination stages. The multicycle capture performance of...

The Calcium Looping (CaL) process, based on the carbonation/calcination of CaO, has been proposed as a feasible technology for Thermochemical Energy Storage (TCES) in Concentrated Solar Power (CSP) plants. The CaL process usually employs limestone as CaO precursor for its very low cost, non-toxicity, abundance and wide geographical...

The Calcium Looping (CaL) process, based on the cyclic carbonation/calcination of CaO, has emerged in the last years as a potentially low cost technique for CO2capture at reduced energy penalty. In the present work, natural limestone and dolomite have been pretreated with diluted acetic acid to obtain Ca and Ca-Mg mixed acetates, whose...

Deep penetration of renewable energies into the grid relies on the development of large-scale energy storage technologies using cheap, abundant, and nontoxic materials. Concentrated solar power (CSP) is particularly suitable to massively store thermal energy for dispatchable electricity generation. This is currently accomplished in a few...

La presente invención propone el empleo de escoria de acería pretratada para el almacenamiento termoquímico de energía solar concentrada (CSP) mediante la integración de esta tecnología con el proceso "Calcium Looping" (CaL). La escoria de acería es un material de bajo coste, abundante y no-tóxico. El CaO derivado del tratamiento de la escoria...

A straightforward method for the preparation of trisphosphinite ligands in one step, using only commercially available reagents (1,1,1-tris(4-hydroxyphenyl)ethane and chlorophosphines) is described. We have made use of this approach to prepare a small family of four trisphosphinite ligands of formula [CH3C{(C6H4OR2)3], where R stands for Ph...
