Random copolymers have been extensively utilized in this field due to their straightforward synthetic methods compared to block copolymers. However, achieving precise control over the nanostructure of these random copolymers is challenging, owing to the irregular distribution of hydrophilic and hydrophobic segments along their backbone. Herein, we introduce the acid doping-induced phase separation of random copolymers containing basic moieties driven by base–acid interaction with phosphoric acid (PA). Small-angle X-ray scattering analysis revealed that increased functionalization led to phase separation and inversion, indicative of dispersed PA distribution, impacting membrane morphology and phase dynamics. The phase morphology control improves proton conductivity and PA retention up to 130% and 260% increases, respectively, resulting in a significant enhancement in power density, a 20% boost to 200 mW/cm2.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142276375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the issue of their terrible battery life and rate capability continues to be their hindrances. A set of three-factor, three-level orthogonal experiments was adopted, including the calcination temperature, calcination time, and heating rate. And two single-factor experiments were carried out to further optimize the preparation conditions. Finally, the optimal conditions were obtained as follows: the calcination temperature was 900 °C, the calcination time was 12 h, and the heating rate was 5 °C min–1. The layered oxide cathode material Co-free P2-Na2/3Fe1/2Mn1/2O2 was synthesized by the solid phase method. Under the control of the optimal conditions, the P2-Na2/3Fe1/2Mn1/2O2 cathode could yield a remarkable initial discharge specific capacity (179.3 mAh g–1, 0.1 C) and cycle stability (54.6% over 50 cycles).

The present study reports the synthesis of a series of three-layer S–A perovskites (A3X1 hybrids), Bi4AA′Ti2NbO14Cl (A, A′ = Sr and Ba), by an innovative approach involving interchange of Sr and Ba between the starting Sillén and Aurivillius blocks to examine the cation redistribution in the resulting intergrowth phases. Rietveld structure refinements reveal the preferred occupation of Sr in the perovskite block, while the larger Ba is grounded in the Sillén block. Due to cation migration between the fluorite-like [Bi2O2] layer and the perovskite block during intergrowth formation, the projected composition Bi4Ba[P]Sr[S]Ti2NbO14Cl (where [P] indicates the perovskite block, while [S] indicates the fluorite block) evolves into the phase with a mixed cation distribution, Bi4Ba0.1[P]Sr0.9[P]Ba0.9[S]Sr0.1[S]Ti2NbO14Cl. The cation migration appears to improve the packing by simultaneously reducing the height of the perovskite block and decreasing the divergence in the Bi–O bond lengths of the fluorite block simultaneously. This leads to greater mixing of Ti-3d, Nb-4d, and Bi6p states contributing near the conduction band minima. The cation-migrated S–A hybrid shows enhanced photocatalytic hydrogen evolution (PHE) as compared to the hybrid perovskites with nonmigrated or unmixed cation distribution. The present investigation discusses the innovative synthesis, cation migration, site disorder, and first-principles electronic structure calculations to unveil their role in enhanced PHE.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":null,"pages":null},"PeriodicalIF":6.4,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142187885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
