Utilizing on density functional theory (DFT) investigation, this paper comprehensively examines H₂ storage properties on superalkali OLi₃ cluster decorated graphene and the results expose that the OLi₃ cluster can firmly bind on graphene owing to the highest binding energy of −2.87 eV. Moreover, double sides of OLi₃-decorated graphene can hold the maximum number of 18 H₂ molecules, achieving an ideal H₂ adsorption energy of −0.201 eV/H₂ as well as the satisfied hydrogen storage capacity of 7.29 wt%, which exceeds the specified target of 5.5 wt% by U.S. Department of Energy (DOE) for 2025 year. The obtained partial density of states (PDOS), charge density difference (CDD) and the isosurface of electrostatic potential (ESP) clearly reflect the H₂ adsorption mechanisms, which mainly consists of orbital hybridization and polarization effect. In addition, ab initio molecular dynamics (AIMD) simulations guarantee an excellent thermodynamic stability for 18H₂/2OLi₃/G system at 300 K through 3 ps simulations and the H₂ molecules can be quickly released under higher temperature in basis of the recovery times (<em>τ</em>). Furthermore, the N-P-T diagram shows the adsorption conditions of H₂ molecules require low temperature and high pressure while the conditions of desorption are just the opposite. Our theoretical predictions can pave the way for the experimental synthesis of high capacity hydrogen storage materials.</div></div>","PeriodicalId":11266,"journal":{"name":"Diamond and Related Materials","volume":"156 ","pages":"Article 112461"},"PeriodicalIF":4.3,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084592","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}

The present study investigates the transport processes and erosion mechanisms of NaCl solutions within the channels of calcium silicate hydrated (C-S-H), C-S-H branched graphene (Gr), functionalized graphene oxide (GO-O, GO-OH and GO-COOH) and 2D-silica (NS) at different temperatures (250 K–400 K) by molecular dynamics. The results obtained demonstrate that the NaCl solution exhibits a half-crescent shape transport in the C-S-H channels and that the solution can pass through the nano-channels at a faster rate as the temperature increases. Elevated temperature increases diffusion, which weakens the bonding strength between the nanomaterials and C-S-H. Gr exhibits a strong repulsion of water and ions. GO-O gradually separates from the C-S-H surface with increasing temperature, proving that its interaction with C-S-H is slowly weakened. Aggregation of NS occurs, forming larger particles to reduce fluidity, and increasing temperature helps to increase diffusion. Oxygen in GO-OH and GO-COOH readily accepts hydrogen bonds and binds to sodium ions, thus immobilizing ions and water molecules on the GO surface. As the temperature increases, the distance of hydrogen bonding increases, but the RDF peak increases, showing that the intermolecular interactions remain strong, which enhances the hydrophilicity of the material. Density Functional Theory (DFT) studies have shown that the adsorption of Ca²⁺, Na⁺, H₂O and Cl⁻ by Gr, GO and NS are Ca²⁺&gt;Na⁺&gt;H₂O &gt; Cl⁻.The rate of diffusion of water shows a different order with temperature in various materials, especially at high temperatures where certain materials have better diffusion properties. The dissociation of water molecules and Ca²⁺ increases with increasing temperature, leading to a decrease in the binding strength between C-S-H and the nanomaterials. The study in this paper will help to reveal the subtle mechanisms of capillary transport in C-S-H nanopores at different temperatures, thus providing a more scientific basis for the design and optimization of cementitious materials. With a better understanding of these mechanisms, we can further promote the development of advanced cementitious materials and enhance their performance and durability in engineering applications.</div></div>","PeriodicalId":11266,"journal":{"name":"Diamond and Related Materials","volume":"157 ","pages":"Article 112456"},"PeriodicalIF":4.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144146951","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}
