Colloidal plasmonic metal nanoparticles have enabled surface-enhanced Raman scattering (SERS) for a variety of analytical applications. While great efforts been made to create hotspots amplifying signals, it remains challenge ensure their high density and accessibility improved sensitivity the analysis. Here we report dealloying process fabrication porous Au-Ag alloy containing abundant inherent hotspots, which were encased in ultrathin hollow silica shells so that need conventional organic...
Oxygen evolution reaction (OER) plays a key role in energy conversion and storage processes such as water splitting carbon dioxide reduction. However, the sluggish kinetics caused by insufficient active surface limited charge transfer hinder OER's wide applications. In this work, novel self‐templating strategy for fabrication of composite CoO–MoO 2 nanocages with enhanced OER performance is proposed. By designing nanocage structure incorporating conductive MoO to promote both mass transfer,...
Abstract Ionic liquids (ILs) are a family of nonconventional molten salts that offer many advantages, such as negligible vapor pressures, flammability, wide liquidus ranges, good thermal stability, and much synthesis flexibility. The unique solvation environment these ILs provides new reaction or flux media for controlling formation solid‐state materials with minimum perturbation morphologies. A successful lithiation via ionothermal using cost‐effective Li halide source recyclable solvents...
Manipulating the selectivity-determining step in post-C–C coupling is crucial for enhancing C2 product specificity during electrocatalytic CO2 reduction, complementing efforts to boost rate-determining kinetics. Here we highlight role of single-site noble metal dopants on Cu surfaces influencing C–O bond dissociation an oxygen-bound intermediate, steering toward ethylene versus ethanol. Integrating theoretical and experimental analyses, demonstrate that oxygen binding strength surface...
Abstract Separation of electrode materials from their current collectors is an enabling step toward recovering critical spent lithium‐ion batteries. In the presented research, a highly efficient, cost‐effective, and environmentally sustainable separation process was developed for that purpose. Ethylene glycol, vital commodity chemical as antifreeze polymer precursor, used to delaminate at low temperatures in seconds without altering crystalline structure morphology active materials. The...
Effective separation of cathode materials and current collectors is one the most enabling steps, yet a very challenging step, in recycling electrode scraps spent Li-ion cells. Here, green solvent, triethyl phosphate, was used to recover invaluable cobalt-containing cathodes, such as NMC622, by dissolving polymeric binder poly(vinylidene fluoride). Electrochemically active were separated from collected at manufacturing step electrodes through solvent-based method without jeopardizing their...
The proper handling of end-of-life (EOL) lithium-ion batteries (LIBs) has become an urgent and challenging issue with the surging use LIBs, in which recovering high-value cathodes not only relieves pressure on raw material supply chain but also minimizes environmental pollution. Beyond direct recycling spent to their pristine states, upcycling next-generation is great significance maximize value materials sustain fast development LIBs. Herein, a "reciprocal ternary molten salts" (RTMS)...
Identification of active sites for oxygen evolution reaction (OER) plays a key role in the design and fabrication high-performance cobalt-based electrocatalysts. Herein, we report synthesis two types two-dimensional monometallic cobalt hydroxide nanoplates aqueous solution OER: α-Co(OH)2 with both Co2+Td Co2+Oh β-Co(OH)2 sites. Electrochemical characterization reveals that is more than towards OER. The better activity can be attributed to presence α-Co(OH)2, which are Our finding clarifies...
Dynamic manipulation of optical properties through the reversible assembly plasmonic nanoparticles offers great opportunities for practical applications in many fields. The previous success, however, has been limited to Au nanoparticles. Reversible and tuning Ag (AgNPs) have remained a significant challenge due difficulty finding an appropriate surface agent that can effectively stabilize particle control their interactions. Here, we overcome by developing limited-ligand-protection (LLP)...
A novel ratiometric surface-enhanced Raman scattering (SERS) nanosensor has been developed to probe the activity of endonuclease under in vitro and living cells conditions. The optimized alloyed Au/Ag nanoparticles (NPs) were synthesized as SERS substrate, which combined superior properties both pure Au Ag nanoparticles: they exhibit excellent plasmonic property with high chemical stability low cytotoxicity. They then employed for quantitative detection through functionalization...

Plasmonic noble metal nanocrystals with interior nanogaps have attracted great attention in surface-enhanced Raman scattering (SERS) applications due to the presence of built-in hotspots.

Here, this study reports a novel confined‐space thermal dewetting strategy for the fabrication of Au nanocups with tunable diameter, height, and size cup opening. The nanocup morphology is defined by cup‐shaped void space created yolk–shell silica template that spontaneously takes an eccentric configuration during annealing. Thermal Au, which sandwiched between yolk shell, leads to desired morphology. With strong scattering in near infrared, exhibit superior efficiency as contrast agents...
