In terms of overcoming the difficulty in studying the particle size effects (due to the coexistence of both large and small particles and wide particle distribution) in metal-induced photocatalysis, design strategies are crucial in developing plasmonic-photovoltaic systems with enhanced efficiency. In this work, we first introduce the light absorption by differently shaped metal nanoparticles and address their morphology-induced improved photocatalysis mechanisms in several well-known dye degradation reactions, based precisely on their spectroscopic and microscopic evidence. The shape of the metal nanoparticles plays an important and active role in their respective photocatalytic performance, with the availability of surface energy-based active sites along with better accessibility to interact with the surrounding reaction medium, thus advantageous in high-resolution sensing and energy storage applications. The integration of such plasmonic metal NPs with perovskite semiconductors results in the formation of metal–semiconductor composite (MSC) materials with enhanced solar-light-harvesting ability based on FDTD simulations, thereby providing a potential solution for the well-recognized challenge in the field of solar energy conversion. The plasmonic metal-induced photosensitization improves the photo-absorption limitation of perovskite semiconductors to a large extent, rendering them efficient visible-light-responsive photocatalysts. Additionally, these MSC-based perovskite films display enhanced crystallinity, larger grain size, and reduced surface roughness, thus exhibiting short circuit current, fill factor, and power conversion efficiency when compared to the control device.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"179 ","pages":"Article 114762"},"PeriodicalIF":4.4,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144177508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This manuscript examines MgSb₂O₆ material structural, thermodynamic, electronic, optical, and mechanical properties utilizing density functional theory (DFT) simulations. Additionally, we investigate the effects of hydrostatic pressure ranging from 0 to 70 GPa on these physical properties. Our study presents the first theoretical framework for analyzing the behaviour of MgSb₂O₆ under pressure, offering valuable insights into its properties. The compound retains a tetragonal crystal structure across this pressure range, and the derived lattice constants align with those reported in other experimental studies. Moreover, the thermal properties of the MgSb₂O₆ compound have been determined, including enthalpy, free energy, heat capacity, entropy, and Debye temperature, which can support future experimental and theoretical investigations of this material. Due to their high Debye temperatures, the components under study exhibit relatively high melting points. The electronic density of states (DOS) and electronic band structures were evaluated with the GGA-PBE exchange correlation function, the results reveal that the direct (Γ-Γ) energy bandgap value increases and shifts in the ultraviolet spectrum by applying pressures from 0 to 70 GPa. The optical properties of the MgSb₂O₆ compound are described in detail, including dielectric function, absorption, reflection, conductivity, and refractive index, which highlight the potential of this material for optoelectronic and engineering applications. The increase in the elastic modulus value indicates that MgSb₂O₆ becomes stiffer under stress. The Poisson’s and Pugh’s ratios also show that the compound transforms from brittle to ductile when pressure is applied. Pressure significantly affects this material’s anisotropy factor, causing deviations from a spherical shape.
