Abstract Integrating plasmonic nanoparticles into the photoactive metal-organic matrix is highly desirable due to near field enhancement, complementary light absorption, and accelerated separation of photogenerated charge carriers at junction interface. The construction a well-defined, intimate interface vital for efficient carrier separation, however, it remains challenge in synthesis. Here we synthesize bearing interface, composed Ag with silver node via facile one-step approach. effect on...
Abstract Plasmonic nanoparticles (NPs), such as Au, Ag, and Cu, are considered promising photothermal materials attract extensive attention for freshwater production by solar steam generation. However, high cost, narrow absorption range and/or poor stability greatly limit their practical applications. Herein, a high‐efficiency energy conversion material consisting of low‐cost non‐metal, extremely thermally‐stable plasmonic TiN NPs hydrophilic semi‐reduced graphene oxide (semi‐rGO), with...
Emerging rechargeable aluminium batteries (RABs) offer a sustainable option for next-generation energy storage technologies with low cost and exemplary safety. However, the development of RABs is restricted by limited availability high-performance cathode materials. Herein, we report two polyimide two-dimensional covalent organic frameworks (2D-COFs) cathodes redox-bipolar capability in RAB. The optimal 2D-COF electrode achieves high specific capacity 132 mAh g-1 . Notably, presents...
This paper describes a general method to drastically improve the dispersity of oleic acid stabilized nanoparticles in aqueous solutions. We use monodisperse iron oxides and silver as model systems, have modified surface properties these through formation an inclusion complex between surface-bound surfactant molecules α-cyclodextrin (α-CD). After modification, both oxide Ag can transfer from hydrophobic solvents, such hexane, α-CD phase. The efficiency phase solutions depends on initial...
The most studied effect of surface-enhanced Raman scattering (SERS) hotspots is the enormous enhancement analytes therein. A less known effect, though, that formation may cause trapped to change molecular orientation, which in turn leads pronounced changes SERS fingerprints. Here, we demonstrate this by creating and characterizing colloidal solutions. Anisotropically functionalized Au nanorods were synthesized, whereby sides specifically encapsulated polystyrene-block-poly(acrylic acid),...
A new class of SERS nanoprobes is reported, where analyte-tagged metal nanoparticles are encapsulated with block copolymers to provide core–shell structures that stable against salt and oxidant. The facile scalable synthesis gives large quantities readily purified. Nearly all singly encapsulated, allowing unambiguous estimate enhancement factors free "hot-spots". Multiplexing capability demonstrated.
Ag is deposited on the surface of Au nanoparticles functionalized with 4-mercaptobenzoic acid (MBA). Exceptionally strong surface-enhanced Raman scattering (SERS) signals are observed from resulting colloid. Using SERS as a tool, evidence obtained for embedding MBA inside nanoscale metal layer.

Abstract Conversion of clean solar energy to chemical fuels is one the promising and up-and-coming applications metal–organic frameworks. However, fast recombination photogenerated charge carriers in these frameworks remains most significant limitation for their photocatalytic application. Although construction homojunctions a solution, it very challenging synthesize them. Herein, we report well-defined hierarchical homojunction based on via facile one-pot synthesis route directed by hollow...
Titanium dioxide (TiO2) as a common photothermal material usually faces with low conversion efficiency, mainly owing to the little utilization of visible (Vis) and near-infrared (NIR) light in solar spectrum. Introducing oxygen vacancies is an effective strategy for narrowing its bandgap thus enhancing absorption capacity. However, traditional approaches are always not energy-efficient or unable create enough vacancies. Herein, laser ablation liquid (LAL) was successfully employed prepare...

Nanoparticles (NPs) can be conjugated with diverse biomolecules and employed in biosensing to detect target analytes biological samples. This proven concept was primarily used during the COVID-19 pandemic gold-NP-based lateral flow assays (LFAs). Considering gold price its worldwide depletion, here we show that novel plasmonic NPs based on inexpensive metals, titanium nitride (TiN) copper covered a shell (Cu@Au), perform comparable or even better than nanoparticles. After conjugation, these...
