{"title":"SERS Reveals Counterion-Controlled Au(I)/Au(III) Speciation in Thiocyanate-Mediated Gold Nanowire Growth","authors":"Mari N.Luumi,Adalberto Vasconcelos Sanches de Araujo,Ibrahim Abdelsalam,Pedro Camargo,Rômulo Augusto Ando","doi":"10.1039/d6nr02148d","DOIUrl":"https://doi.org/10.1039/d6nr02148d","url":null,"abstract":"Understanding how coordination chemistry governs nanoparticle growth requires direct identification of the metal–ligand complexes that precede reduction. Here, we show that thiocyanate-mediated gold nanowire formation proceeds through distinct Au–SCN complexes whose oxidation state is determined by the counterion. Using surface-enhanced Raman scattering (SERS) calibrated by density functional theory (B3LYP/def2-TZVPP/D3(BJ)), we resolve the ν(C≡N) signatures of the active Au–SCN intermediates that persist in the as-synthesized colloids. With the imidazolium thiocyanate ionic liquid (EMISCN), the band at 2121 cm⁻¹ matches the computed signature of [Au(SCN)₂]⁻ (Au(I), 2119 cm⁻¹); under sodium-based conditions (NaSCN), the band at 2128 cm⁻¹ aligns with [Au(SCN)₄]⁻ (Au(III), 2131 cm⁻¹). Despite producing wire-like nanostructures in both cases (mean diameters 40 nm and 14 nm, respectively), these systems follow different oxidation-state pathways. Control experiments show that thiocyanate added after nanoparticle formation gives ν(C≡N) positions distinct from both synthesis-derived signatures and induces no anisotropic growth, indicating that the structure-directing species forms prior to reduction in solution. These findings establish SERS as a practical probe of reactive speciation and identify the counterion as a controlling parameter for selecting mechanistic pathways in anisotropic nanoparticle synthesis.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"32 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173199","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}

Herein, a slow-growth kinetics favoured synthetic strategy sequenced by solid-state phosphorization was employed to fabricate a synergistically favourable bimetallic NiCoP electrocatalyst possessing a hierarchical thistle flower-like microarchitecture. The physicochemical characteristics of resultant NiCoP exhibit significant mesoporosity, interconnected hierarchical mesopore channels, low crystallite dimensions, specific surface area of 52.9 m2 g–1, multivalent Ni/Co redox centers and catalytically active phosphide nanodomains along with amorphous phosphate layers constituting phosphide/phosphate heterointerface at the surface of NiCoP thistles. The electrochemical investigations reveal highly reversible redox characteristics, elevated electrocatalytically active sites, substantial electrochemically active surface area (357 cm2 corresponding to Cdl value of 14.3 mF or 72.9 mF cm–2), low onset potential and favourable interfacial charge-transfer kinetics toward alkaline OER. Consequently, the NiCoP electrocatalyst displays remarkable OER activity with a overpotential of 285±2.65 mV (at 10 mA cm–2), a Tafel slope of 113 mV dec–1, low charge-transfer resistance of 4.6 Ω and an apparent turnover frequency of 6.72 s–1, along with excellent operational durability over 18 h amperometric i–t and 24 h chronopotentiometric operations. The superior electrocatalytic efficacy is attributed to the electrochemical synergistics between multivalent Ni and Co species, abundant catalytically accessible low-dimensional phosphide active sites, and hierarchically interconnected mesoporous channels that collectively facilitate electrolyte-ion diffusion, rapid charge transport, enhanced OH– adsorption kinetics, and efficient release of evolved oxygen bubbles during prolonged OER operation. Furthermore, the robust mesoporous microstructural framework effectively mitigates electrochemical degradation and stablizes the partially-reconstructed catalytically active phase during anodic OER conditions. Overall, the present study establishes hierarchically architectured and synergistically favourable bimetallic phosphides as promising non-noble alternatives to conventional OER electrocatalysts for advanced alkaline oxygen electrochemistry and sustainable energy technologies.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"14 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173201","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}

This work leverages the synergistic combination of two emerging liquid metal-based concepts—liquid metal doping and liquid metal bridge solubility—for the generation of ultrathin FTO layers, reducing reliance on current energy-intensive and hazardous chemical vapour deposition (CVD) processes. Here, tin (Sn) and silver fluoride (AgF) are melted together to form a homogeneous liquid, from which the surface oxide is transferred onto a solid substrate. While Ag plays an essential role in facilitating the incorporation and solubility of F in Sn, its presence at the liquid metal surface is restricted due to its very low tendency to oxidise at the surface. The technology enables the harvesting of multilayer architectures at moderately low temperatures and under ambient atmospheric conditions. The harvested FTO nanosheets exhibited a thickness of up to 10 nm, enhanced conductivity, and a transparency of 80% in the visible region. Tin oxide (SnO₂), obtained from a similar liquid metal-based deposition process, was also used as a reference for comparison.

Herein, a Co/N-codoped hierarchical porous carbon nanoreactor, denoted as N-PC@dCo, is constructed from a PDA-coated ZnCo-ZIF precursor through controlled carbonization. During pyrolysis, Zn evaporation generates abundant hierarchical pores, the PDA-derived carbon shell strengthens physical confinement and electronic conductivity, and Co/N active sites provide polar adsorption and catalytic centers for potassium polysulfide conversion. Benefiting from the integrated confinement-adsorption-catalysis effect, the N-PC@dCo/S cathode effectively suppresses polysulfide migration, accelerates K2S nucleation/decomposition, and reduces sulfur redox polarization. As a result, the optimized sample delivers a high reversible capacity of 868.2 mAh g−1 after 50 cycles at 0.1 A g−1, and maintains a long cycling stability over 1000 cycles at a high current density of 5 A g−1. Mechanistic studies reveal that the synergistic effect between Co species and N-doping sites effectively accelerates the redox kinetics of polysulfides, thereby significantly suppressing the shuttle effect. This work provides a rational nanoreactor design strategy for regulating potassium polysulfide chemistry toward durable K–S batteries.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"85 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173207","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}

Herein, we present a self-supporting hierarchical VO2@MXene electrode without current collector and additive for AZIBs, where VO2 nanostructures are intimately anchored within a highly conductive MXene layers. The highly conductive and highly flexible Mxene forms a high-conductivity network, facilitating the rapid transmission of electrons/ions, while providing a buffer for the structural changes of VO2, effectively promoting the structural robustness during the cycling process. Systematic investigation reveals a strong synergistic effect between VO2 and MXene. With an optimal VO2-to-MXene mass ratio of 1:1, the cathode delivers a high discharge capacity of 587.7 mA h g -1 at 1 A g -1 and maintains a remarkable capacity of 361.1 mA h g -1 after 1000 cycles at 5 A g -1 .
