Based on the inherent amphoteric properties of SNWs, multicompatibility was explored to facilely composite SNWs with various polymers for preparation of coextruded membranes with enhanced performance and endowed the composites with protein-endowed double adsorption properties. Overall, this work demonstrated that the DES pretreatment process is promising for green and low-cost biopolymer nanomaterial extraction and that the SNWs prepared via DES have good prospects as nanoscale materials in the environmental field and in development of smart biomaterials and drug delivery in biomedicine.We report the facile synthesis methods of four materials, with the general formula SrMnO3-δ, which have previously been synthesized in multiple steps, involving switching between different oxidizing and reducing gases, quenching, the use of zirconium metal as a reductant, etc. However, we have shown that it is possible to synthesize all of these materials by facile processes without unnecessary complications. In fact, we have found methods of synthesizing the oxygen-deficient phases in only one step. Given the diverse range of structures that are formed for SrMnO3-δ, we have investigated the correlations between the structural order and electrocatalytic activity for the oxygen evolution reaction (OER) of water splitting. We have uncovered a systematic trend in the OER activity, where the most oxygen-deficient compound, SrMnO2.5, which features square-pyramidal coordination geometry around manganese, shows the highest OER performance. The next OER activity belongs to SrMnO2.6, which contains both MnO5 trigonal bipyramids and MnO6 octahedra. SrMnO3(cubic), containing only corner-sharing MnO6 units, shows the third best OER
