MnO₂, known for its abundant structure and outstanding catalytic performance, is one of the most promising candidates for VOCs degradation. Based on the X-ray diffraction, scanning electron microscopy, and transmission electron microscope measurements, fiber-like α-MnO₂, rod-like β-MnO₂, flower-like δ-MnO₂, urchin-like γ-MnO₂, and particle-like ε-MnO₂ were successfully built. The X-ray photoelectron spectroscopy results revealed higher oxygen vacancy and adsorbed oxygen concentrations on the γ-MnO₂ surface. The relationship between the distinct morphologies, crystalline phases and their catalytic activity for benzene oxidation were investigate. The thermal catalytic activities followed the order of γ &gt; α &gt; δ &gt; β &gt; ε-MnO₂ by conventional heating. Benefiting from the stronger low-temperature reducibility and the better low-temperature mobility of oxygen species, urchin-like γ-MnO₂ showed the highest activity (T₅₀ = 195 °C and T₉₀ = 220 °C) over thermal benzene oxidation.

Higher catalytic properties by microwave heating than conventional heating was achieved through crystal phase and structure regulation.

However, many photocatalytic materials still face limitations such as insufficient light absorption efficiency, moderate carrier separation, and poor stability under practical conditions. Heterojunction photocatalysts, by tailoring their band structure and lattice matching, effectively enhance photocatalytic performance, representing a crucial strategy to overcome these limitations. This study employs first-principles calculations to investigate the geometric structure, electronic properties, and photocatalytic performance of several two-dimensional (2D) layered heterojunctions: GaS/SnC, GaS/PtS₂, GaS/HfS₂, and GaS/ZrS₂. The results demonstrate that these heterojunctions exhibit an S-scheme band alignment, which reduces the band gap and promotes the separation of photogenerated carriers. The difference in work functions generates an internal electric field, driving electron-hole migration along an S-shaped pathway, thereby suppressing electron-hole recombination and aligning the band edge positions with the redox potentials for water splitting. Notably, GaS/SnC exhibits significantly improved carrier mobility and relaxation time, indicating suppressed carrier-phonon scattering and efficient charge transport. Our findings suggest that GaS-based heterojunctions are promising S-scheme photocatalysts for water splitting. In particular, the GaS/SnC heterojunction displays a significant red-shift and enhanced visible light absorption, indicating its potential for applications in optoelectronic devices and solar energy conversion.</div></div>","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"707 ","pages":"Article 163646"},"PeriodicalIF":6.3,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144153870","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}
