The SrCO3/SrO system for thermochemical energy storage at ultra-high temperature
(Elsevier, 2022)
Thermochemical energy storage (TCES) has attracted interest in the last years due to the possibility of attaining high energy densities, seasonal storage capacity and greater efficiencies than currently commercial thermal ...

Kinetics and cyclability of limestone (CaCO3) in presence of steam during calcination in the CaL scheme for thermochemical energy storage
(Elsevier, 2021)
In the present work, we explore the use of steam in the CaCO3 calcination step of a calcium looping process devised for integration into a thermochemical energy storage process (CaL-TCES). Steam produces a double benefit: ...

Sustainable routes for acetic acid production: Traditional processes vs a low-carbon, biogas-based strategy
(Elsevier, 2022)
The conversion of biogas, mainly formed of CO2 and CH4, into high-value platform chemicals is increasing attention in a context of low-carbon societies. In this new paradigm, acetic acid (AA) is deemed as an interesting ...

Recent advances on gas-phase CO2 conversion: Catalysis design and chemical processes to close the carbon cycle
(Elsevier, 2022)
Chemical CO2 recycling in the gas phase constitutes a straightforward approach for effective CO2 conversion to added-value products like syngas or synthetic methane. In this scenario, some traditional processes such as the ...

Activation of Si-H and B-H bonds by Lewis acidic transition metals and p-block elements: same, but different
(Royal Society of Chemistry, 2022)
In this Perspective we discuss the ability of transition metal complexes to activate and cleave the Si–H and B–H bonds of hydrosilanes and hydroboranes (tri- and tetra-coordinated) in an electrophilic manner, avoiding the ...

Alkane Metathesis over Immobilized Pincer-ligated Iridium Complexes: Effect of Support Nature
(Elsevier, 2023)
In this work, catalytic alkane metathesis has been evaluated as a suitable approach to upcycle hydrocarbons (polyolefins) at moderate temperatures. To this end, a pincer-ligated iridium complex (dehydrogenation catalyst) ...
