Among various hydrogen production methods, the hydrolysis of Ammonia borane (NH₃BH₃/AB) has been widely favored for its eco-friendly properties. However, developing high-performance non-precious metal catalysts remains a key challenge in this field. In this study, the interfacial electronic states were controlled by fabricating CuCo₂O₄-CuO heterojunctions exhibiting built-in electric fields (BIEF). At the heterogeneous interface, charge transfer driven by work function differences results in a cooperative active site featuring an electron-rich CuCo₂O₄ region and an electron-deficient CuO region. Furthermore, under the electrostatic adsorption driven by BIEF, AB and H₂O molecules are efficiently adsorbed and activated, thereby endowing CuCo₂O₄-CuO with remarkable catalytic activity. The hydrogen evolution reaction (HER) rate of this material is 2.29 times higher than that of single-component CuCo₂O₄ and 43.0 times greater than that of single-component CuO, demonstrating performance comparable to supported catalysts.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"65 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144521479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the equiaxed microstructure is obtained by multi-DOF forming process. Microstructural analysis reveals that grain size is refined from 6.94 μm of as-sintered composite to 4.96 μm of multi-DOF formed composite. The refinement mechanism is primarily governed by synergistic interactions between continuous dynamic recrystallization and discontinuous dynamic recrystallization (CDRX/DDRX). Subsequent high-temperature tensile testing of as-sintered and multi-DOF formed composites across the 400-800 ℃ thermal regime elucidates distinct temperature-dependent strength and plasticity enhancement mechanisms. When the tensile temperature ranges from 400 to 600 ℃, the multi-DOF formed composite shows improved strength and plasticity compared to the as-sintered composite. The strengthening mechanisms include Hall-Petch strengthening through grain refinement, TiB load transfer strengthening, and TiB-induced dislocation pinning effect. Concurrently, the plasticity mechanisms correlate with the activation of more prismatic slip systems. When the tensile temperature ranges from 700 to 800 ℃, both the strength and plasticity of multi-DOF formed composite still increase compared to the as-sintered composite. However, the magnitude of strength enhancement is relatively small, while the magnitude of plasticity enhancement is relatively large. The small magnitude of strength enhancement can be attributed to the grain boundary softening effect. The large magnitude of plasticity enhancement is primarily attributed to grain boundary sliding (GBS) and the fact that the TiB phase facilitates dynamic recrystallization at elevated temperatures.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"152 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144516294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
