New approach to consecutive CO oxidation and CO₂ chemisorption using Li₂CuO₂ ceramics modified with Na- and K-molten salts

Abstract

A series of X-containing Li2CuO2 (X=Na and/or K) materials were prepared by mechanically adding different mixtures of sodium and potassium carbonates onto a previous lithium cuprate prepared by solid-state reaction....

Insight into CO selective chemisorption from syngas mixtures through Li2MnO3; a new H2 enrichment material

“…follow the reaction described in eqn (11), where the maximum capture corresponded to a weight increment of 18% and involves the evolution of the Li 2 MnO 3 to MnO.…”

“…Within this context, calcium oxide-containing ceramics seem to possess excellent properties as carbon oxides captors within the sorption-enhanced processes, 5–8 although other alkaline and earth-alkaline ceramics have also been analysed, such as MgO and Li 4 SiO 4 . 9–11 All these works have evidenced that SER processes exhibit great potential in decarbonizing hydrogen production.…”

Investigation of palladium catalysts in mesoporous silica support for CO oxidation and CO2 adsorption

“…We recently reported mesoporous silica aerogel-supported palladium catalyst (Pd/SiO 2 ) for low-temperature CO oxidation under ignition/extinction cycles with excellent stability [ 12 ]. The idea of using the same nanomaterials that serve as a catalyst for CO oxidation as a sorbent was recently reported by several groups [ [8] , [9] , [10] , 33 ]. However, some of the materials used in these studies suffer poor stability at higher temperatures.…”
