In this study, the layered GDY was synthesized using the ball milling method, and Zn0.5Cd0.5S/Graphdiyne/NiO (ZnCdS/GDY/NiO) composite was synthesized by in-situ composite and physical mixing method. The prepared ZnCdS/GDY/NiO has good photostability outstanding performance in photocatalytic hydrogen production. When exposed to 5 W of white light, the ZnCdS/GDY/NiO photocatalyst demonstrates a hydrogen production rate of 24.44 mmol·g-1·h-1, which was 8.4 times greater than that of pure Zn0.5Cd0.5S under the same conditions. Various characterization tests and theoretical calculations show that the improved photocatalytic efficiency resulted from the formation of a dual S-scheme heterostructure in the ZnCdS/GDY/NiO composite catalyst, which promoted the recombination of relatively useless photogenerated electron holes. Furthermore, strong photogenerated holes and electrons in the more positive valence band (VB) and the more negative conduction band (CB) were retained, which significantly improved the photogenerated carrier separation ability of the composite catalyst, and thus enhances the hydrogen evolution activity.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"683 Pt 1","pages":"1064-1077"},"PeriodicalIF":9.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142891094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dense CNTs show the intertwined structure features and construct high-speed channels near the surface of the skeletons for efficient thermal conduction, promoting the transport efficiency of heat flow. The regulation of the process leads to a proportion increase in the (1 1 0) crystal plane of the aluminum substrate. The calculation results of non-equilibrium molecular dynamics (NEMD) demonstrate that (1 1 0) crystal plane is conducive to enhancing thermal boundary conductance thus the desirable equivalent thermal conductivity is obtained in the model system. Moreover, the phonon behaviors at the heterointerface observed in phonon density of states spectrums (PDOS) show that the interface system with (1 1 0) crystal plane possesses the superior coupling effect suggesting the brilliant transmission capacity. The theoretical results of NEMD and PDOS provide a microscopic explanation for the high thermal conductivity observed in the prepared composites with a high content of Al (1 1 0) crystal plane.
