Their high surface area, catalytic efficiency, and tunable physicochemical properties enable use in photochemical processes, catalytic converters, biosensing, and therapeutic platforms. In biomedical research, PtNPs exhibit antibacterial, antioxidant, and anticancer activities, making them promising candidates for diagnostics and targeted therapies. This review critically examines recent advances in PtNP synthesis using physical, chemical, and biological approaches, highlighting their respective advantages, limitations, and scalability considerations. Special attention is given to green synthesis strategies employing biological templates as reducing and stabilizing agents. We also summarize characterization techniques and discuss current understanding of PtNP toxicity from in vitro and in vivo studies. Finally, we evaluate biomedical applications, including drug delivery, imaging, and combination cancer therapies, outlining key challenges and research priorities for translating PtNP-based technologies into safe and effective clinical tools.

This study introduces a systematic optimisation approach for synthesising titanium-based lithium-ion sieves (Li₂TiO₃/LTO) via a solid-state reaction using TiO₂ and Li₂CO₃ as precursors, followed by delithiation to produce H₂TiO₃ (HTO). The effects of calcination temperature, heating rate, and Li/Ti molar ratio on structural and functional properties were systematically investigated. Optimal synthesis conditions (Li/Ti ratio 2.0, 850 °C, 9 °C/min) yielded an adsorption capacity of ~ 65 mg/g. Advanced characterisation (XRD, SEM, FTIR, ICP-OES, PSA) confirmed phase purity, nanoscale morphology, and successful delithiation. Kinetic modelling identified the three-dimensional diffusion (Jander) model as most appropriate, with activation energy and pre-exponential factors increasing at higher Li/Ti ratios. Reusability testing demonstrated that HTO outperformed Mn-based sieves, maintaining 55 mg/g after 10 cycles with a Ti dissolution rate of 2.5%. An economic assessment further highlighted the lower operational cost and environmental burden of Ti-based sieves compared to Mn-based alternatives. Overall, the optimised HTO exhibits high adsorption capacity, superior cyclic stability, and economic feasibility, positioning it as a strong candidate for scalable and sustainable lithium recovery from brine.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><img></picture></div></div></figure></div></div>","PeriodicalId":803,"journal":{"name":"Transition Metal Chemistry","volume":"51 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145479578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Substitution of Cd by Mn, Fe, Co, Ni, Cu, Zn, and Hg is examined at two distinct sites. Substitution energies and vibrational frequency analyses confirm that all doped clusters are stable minima, while short molecular dynamics simulations at 300 K verify their dynamical robustness. Bond length and Mayer bond order analyses reveal a systematic progression from ionic (Mn) to covalent (Co, Ni, Cu) bonding, with Zn and Hg behaving as nearly inert <i>d</i>¹⁰ dopants. Hirshfeld charges and magnetic moments corroborate this classification, showing strong correlation between charge transfer, bonding covalency, and magnetic spin states. Electronic analysis demonstrates that TM substitution generally narrows the HOMO–LUMO gap relative to pristine (CdSe)₁₃ (~ 2.3 eV), enhancing conductivity via LUMO stabilization. Mn and Fe retain relatively large gaps (~ 1.2 eV), Co and Ni reduce gaps below 1 eV, and Cu produces the most dramatic narrowing (0.41 eV, Type A). Zn and Hg preserve host-like gaps (&gt; 2 eV), consistent with minimal <i>d–p</i> hybridization. Partial density of states (PDOS) confirm that gap modulation arises from dopant <i>d</i>-orbital participation.
