Efficient degradation of excessive antibiotics in water is worth further exploration. Photocatalytic antibiotic degradation not only makes full use of solar energy, but also exhibits high degradation efficiency and no by-product generation. In this paper, a novel <em>y</em>CeO₂/5Eu-CN photocatalyst with a <em>p</em>-<em>n</em> heterojunction was successfully synthesized by solid-phase methodology, which can effectively photodegrade the antibiotic tetracycline under visible light. Firstly, rare earth Eu ions were doped into the layered g-C₃N₄ prepared by melamine calcination, and then combined with CeO₂ to obtain the effective composite photocatalyst 0.3CeO₂/5Eu-CN. Catalytic exploration indicates that it can effectively photodegrade tetracycline antibiotics with a degradation of 94.0 %, and is recycled three times without loss of photoactivity. Control experiments show 5Eu-CN photocatalyst possesses abundant hole states with a certain width and DOS distribution of VBM through the hybridization of N 2p and Eu 3d, which not only provides more active sites but also exhibits a unique very narrow energy band structure, showing <em>p</em>-type semiconductor characteristics. In addition, 5Eu-CN photocatalyst composites with the <em>n</em>-type semiconductor CeO₂ to form the <em>p</em>-<em>n</em> heterojunction 0.3CeO₂/5Eu-CN. The composite structure efficiently promoted the separation and migration of photogenerated carriers by utilizing the different energy bands of the two semiconductors, significantly suppressing electron-hole pair complexation and enhancing the photocatalytic efficiency. Theoretical calculation also reveals the charge transfer and interaction at the <em>p</em>-<em>n</em> heterojunction interface. This work has achieved innovation in the entire chain of “material design structure – optimization − mechanism elucidation”, providing clearer ideas and theoretical basis for the design of high-performance <em>p-n</em> heterojunction photocatalysts.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"31 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255289","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}

{"title":"Microstructural characteristics and reaction mechanism of ammonium sulfate-promoted cuprite sulfidation","authors":"Xiaodong Jia, Lv Zhao, Jinpeng Cai, Peilun Shen, Dianwen Liu","doi":"10.1016/j.apsusc.2025.164851","DOIUrl":"https://doi.org/10.1016/j.apsusc.2025.164851","url":null,"abstract":"With the depletion of copper sulfide resources, efficient flotation technologies for low-grade copper oxides such as cuprite have garnered considerable attention. Due to the good hydrophobicity exhibited by copper sulfide, sulfidation is generally required for the flotation of cuprite. Meanwhile, ammonium sulfide ((NH₄)₂SO₄) has been widely used as an activator in the sulfidation flotation of cuprite. However, the mechanism through which (NH₄)₂SO₄ enhances the sulfidation effect remains to be systematically elucidated. The study of cuprite’s flotation behavior and surface wettability in this paper reveals that (NH₄)₂SO₄ reduces the depressant effect of excessive Na₂S on cuprite and enhances its flotation efficiency. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) analysis of sulfidation product ions (S₂⁻, S⁻ and Cu₂S⁺) verified the (NH₄)₂SO₄ enhancement of cuprite sulfidation. Microscopic morphology analysis indicates that cuprite surface roughness increased and sulfide products exhibited higher crystallinity and quantity following (NH₄)₂SO₄-enhanced sulfidation. It was revealed by X-ray photoelectron spectroscopy (XPS) analyses that the sulfidation of cuprite was promoted by (NH₄)₂SO₄, as demonstrated by the increase of hydrophobic S₂²⁻ and S_n²⁻ species on the cuprite surface; oxygen was also found to play a crucial role in this process. The main product of direct sulfidation was identified as Cu_7.2S₄ by Grazing-Incidence X-ray Diffraction (GIXRD), and the main product of (NH₄)₂SO₄-enhanced sulfidation was also identified as Cu_7.2S₄ and Cu_1.8S. Furthermore, it has been shown by studies on the solution components that [Cu(NH₃)_n]²⁺ are formed through the combination of (NH₄)₂SO₄ with copper ions, thereby facilitating the dissolution of cuprite. Subsequently, [Cu(NH₃)_n]²⁺ and HS⁻ are caused to react, resulting in the generation of copper sulfide and the release of NH₃. A significant enhancement in cuprite’s sulfidation, a strengthened adsorption of NaBX, and an improved flotation efficiency are all achieved through the oxygen-ammonium synergistic effect.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"10 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255341","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}

Herein, we develop a Ni-MOF/NiCoFe-Prussian blue analogue (NiCoFe-PBA) heterostructure by employing an in-situ growth of NiCoFe-PBA on a 2D Ni-MOF substrate. The formation of this heterogeneous interface significantly enhances charge transfer efficiency. Additionally, the in-situ growth of PBA on the MOF surface effectively mitigates the stacking of 2D Ni-MOF sheets, thereby increasing the exposure of active sites. Furthermore, Ni improves the structural stability of the composite during Na⁺ ion embedding/de-embedding, while Co doping introduces additional electrochemically active sites, significantly boosting the desalination capacity. Therefore, the Ni-MOF/NiCoFe-PBA composite exhibits an excellent desalination capacity of 63.19 mg g⁻¹ in a 500 μS cm⁻¹ NaCl solution, along with good cycling stability. The Na⁺ ion storage mechanism of the Ni-MOF/NiCoFe-PBA composite is thoroughly investigated.

Our findings reveal that both monolayer and bilayer VSe₂ can stably adhere to the LFO (001) surface. Monolayer 1T- and H-VSe₂ exhibit ferromagnetic (FM) characteristics, where the 1T phase is metallic and the H phase is semiconducting.

Bilayer 1T-VSe₂ maintains its metallic character, while bilayer H-VSe₂ with LaO termination exhibits half-metallic properties, and that with FeO₂ termination retains semiconducting, enabling tunable half-metal/semiconductor transitions via LFO substrate engineering.
