Hydrogen-Tolerant LaCaCoFeO Oxygen Transport Membranes from Ultrasonic Spray Synthesis for Plasma-Assisted CO Conversion.

LaCaCoFeO in its various compositions has proven to be an excellent CO-resistant oxygen transport membrane that can be used in plasma-assisted CO conversion. With the goal of incorporating green hydrogen into the CO conversion process, this work takes a step further by investigating the compatibility of LaCaCoFeO membranes with hydrogen fed into the plasma. This will enable plasma-assisted conversion of the carbon monoxide produced in the CO reduction process into green fuels, like methanol.

Multiplying Oxygen Permeability of a Ruddlesden-Popper Oxide by Orientation Control via Magnets.

Ruddlesden-Popper-type oxides exhibit remarkable chemical stability in comparison to perovskite oxides. However, they display lower oxygen permeability. We present an approach to overcome this trade-off by leveraging the anisotropic properties of Nd NiO .
