Copper oxide - perovskite mixed matrix membranes delivering very high oxygen fluxes

Effective degradation of azo dyes in the dark by Cu2+ active sites in CaSrNiCu oxides

“…Therefore, the partial substitution and/or replacement of cations in a mixture of mixed metal oxides offers a range of opportunities to optimise and enhance the catalytic performance. Many of these partially substituted compounds have shown high catalytic activity such as Cu for oxygen transport [22], or as Cu-doped perovskites in the Fenton-like reaction [23,24]. Very recently, Chen et al [25] reported that CaxSr1-xCuO3 perovskite was effective in breaking down the azo bonds of OII dyes reaching 80% degradation in 10 min (OII = 50 ppm) under dark conditions, though mineralisation was low at 30%.…”

The Neck to Particle Ratio Effect on the Mechanical and Morphological Sintering Features of Porous Stainless Steel (SS) Hollow Fibers

“…All rights reserved 3 [2]. Subsequently, dense ceramic hollow fibres based on perovskite materials were developed for oxygen separation from air [3,4]. A common feature of these inorganic hollow fibres is their easy and low cost of fabrication which is desirable for industrial application.…”
