TL;DR: Hydrogen is gaining more and more attention because it is regarded as an important future fuel and recently several new processes, such as photovoltaic–photoelectrochemical water splitting and one-step or multistep thermochemical water splitting based on focused solar or nuclear heat, have been developed.

TL;DR: A new technique to produce O2enriched air by using a mixed-ion and electron-conducting (MIEC) perovskite membrane that combines the in situ O2 supply with permeated O2 and air in one unit is proposed thus simplifying the process of O2 enrichment and reducing the operational and capital costs.

TL;DR: This sustainable process combines N( 2)O removal with the simultaneous production of valuable chemicals with a coupled partial methane oxidation allows N(2)-free synthesis gas to be obtained.

TL;DR: In this article, the partial oxidation of methane to synthesis gas due to CH 4 + 1/2 0 2 → CO + 2H 2 was investigated in a permselective membrane reactor using perovskite hollow fibers for the selective separation of oxygen from air.

TL;DR: In this paper, a perovskite mixed conducting membrane made from the composition BaCo x Fe y Zr z O 3− δ (BCFZ, x ǫ+ǫ yǫ +ǫ zǫǫ = 1.0) in a hollow fiber geometry was used to construct a membrane reactor for the partial oxidation of methane to syngas (CO+H 2 ).
