Exploring the alternative MnO-Na2CO3 thermochemical cycle for water splitting

Authors: Bayon, A; O’Shea, VAD; Serrano, DP; Coronado, JM

Article.
J. CO2 Util.. vol: 42. page: 2212-9820.
Date: DEC. 2020.
Doi: 10.1016/j.jcou.2020.101264.

Abstract:
Thermochemical cycles for H2O and CO2 splitting using CeO2 have demonstrated high efficiency (> 5%) and fast kinetics. Alternative multistage cycles based on stoichiometric oxides, such as Mn-Na, can potentially provide much larger efficiencies under less stringent operation conditions. [read more]
