Brownmillerites CaFeO2.5 and SrFeO2.5 as Catalyst Support for CO Oxidation

open access: yesMolecules, 2021
The support material can play an important role in oxidation catalysis, notably for CO oxidation. Here, we study two materials of the Brownmillerite family, CaFeO2.5 and SrFeO2.5, as one example of a stoichiometric phase (CaFeO2.5, CFO) and one existing ...

Redox‐Active Oxide/molten Salt Composites for Hybrid Thermal‐Chemical Energy Storage

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
Redox‐active oxide–molten salt composites integrate sensible, latent, and thermochemical energy storage within a single particle. A porous Ca2AlMnO5+δ matrix infiltrated with eutectic NaCl/CaCl2 achieves a high‐energy density (267 kJ kg−1) over a narrow, 150 °C temperature window, offering a promising solution for high‐temperature thermal energy ...

Ruddlesden–Popper Structured Sr3Fe2O7−δ as Redox‐Activated CO2 Sorbents for Green Hydrogen Production

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
A‐site and B‐site doped strontium ferrite‐type Ruddlesden–Popper oxides are evaluated as CO2 sorbents for glycerol‐based hydrogen production via sorption‐enhanced steam reforming. A Sr1.4Ca0.6Fe0.9Ni0.1O4−δ composition forms an active Sr3Fe2O7 phase, achieving ≈95 vol% H2 purity and over sixfold longer CO2 prebreakthrough time (tpb) than its perovskite

Crystal and magnetic structures of the brownmillerite Ca2Cr2O5 [PDF]

open access: yesDalton Transactions, 2015
Magnetic moments show a surprising degree of spin canting in the antiferromagnetic structure of the brownmillerite Ca2Cr2O5, obtained from the high pressure perovskite CaCrO3through hard-soft chemistry.

Synthesis and hydration mechanism of a steel‐making by‐product based quaternary binder suitable for superfine tailings

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
• A novel low‐cost SQB was synthesized and optimized for CSTB. • The synergistic hydration mechanism of sulfate‐activated LS with alkali–sulfate‐activated GGBFS in SQB was revealed. • The SQB has effectively consolidated ST, which have significant potential for both environmental and economic benefits.

Devonian micritic limestones used in the historic production of Prague hydraulic lime (‘pasta di Praga’): characterization of the raw material and experimental laboratory burning

open access: yesMateriales de Construccion, 2015
The Devonian micritic limestones from the Prague Basin (Barrandian area, Bohemian Massif, Czech Republic), which were the primary raw material used for natural hydraulic lime burned in Prague, exhibit a feebly to eminently hydraulic character. Based on a

Effect of Activation Mode on the Use of Black Slag in Cementitious Materials for Ecological and Sustainable Construction

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study addresses the environmental challenges of carbon dioxide (CO2) emissions from Portland cement by investigating the valorization of crystalline black slag (CBS) as an eco‐sustainable precursor for geopolymer mortars (GPMs). A novel thermal activation process was employed, where CBS was calcined at 800°C and rapidly water‐quenched to produce ...
