Electrocatalytic reduction reactions (i.e., the hydrogen evolution reaction (HER) and oxygen reaction) at individual, faceted Au nanocubes (NCs) nano-octahedra (ODs) expressing predominantly {100} {111} crystal planes on surface, respectively, were studied by nanoscale voltammetric mapping. Cyclic voltammograms collected individual nanoparticles (NPs) with scanning electrochemical cell microscopy (SECCM) correlated particle morphology imaged electron microscopy. Nanoscale measurements from a...
Palladium octahedrons and tetrahedrons enclosed by eight four {111} facets have been synthesized from cuboctahedral Pd seeds using Na2PdCl4 Pd(acac)2, respectively, as the precursors. Our mechanistic studies indicate that were directed to grow into octahedrons, truncated tetrahedrons, then when Pd(acac)2 was used a precursor. In contrast, same batch of only evolved with increasing sizes precursor switched Na2PdCl4. The difference in growth pattern could be attributed different reduction...
The conversion of CO2 into value-added products is a compelling way storing energy derived from intermittent renewable sources and can bring us closer to closed-loop anthropogenic carbon cycle. ability synthesize nanocrystals well-defined structure composition has invigorated catalysis science with the promise that selectively express most favorable sites for efficient catalysis. performance nanocrystal catalysts reduction reaction (CO2RR) typically evaluated ensembles, which returns an...
Understanding the relaxation and injection dynamics of hot electrons is crucial to utilizing them in photocatalytic applications. While most studies have focused on carrier at metal/semiconductor interfaces, we study situ direct electron from metal adsorbates. Here, report a electron-driven hydrogen evolution reaction (HER) by exciting localized surface plasmon resonance (LSPR) Au grating photoelectrodes. In ultrafast transient absorption (TA) measurements show depletion peak resulting...
Polyhedron packings have fascinated humans for centuries and continue to inspire scientists of modern disciplines. Despite extensive computer simulations a handful experimental investigations, understanding the phase behaviors synthetic tetrahedra has remained fragmentary largely due lack tetrahedral building blocks with tunable size versatile surface chemistry. Here, we report remarkable richness complexity in dimension-controlled assemblies gold nanotetrahedra. By tailoring nanocrystal...

We report a heterometallic seed-mediated synthesis method for monodisperse penta-twinned Cu nanorods using Au nanocrystals as seeds. Elemental analyses indicate that resultant consist predominantly of copper with gold content typically below 3 atom %. The nanorod aspect ratio can be readily adjusted from 2.8 to 13.1 by varying the molar between seeds and precursor, resulting in narrow longitudinal plasmon resonances tunable 762 2201 nm. Studies reaction intermediates reveal symmetry-breaking...
Supercapacitors are widely used in many fields owing to their advantages, such as high power, good cycle performance, and fast charging speed. Among the metal-oxide cathode materials reported for supercapacitors, NiMoO
The self-assembly of shape-anisotropic nanocrystals into large-scale structures is a versatile and scalable approach to creating multifunctional materials. tetrahedral geometry ubiquitous in natural manmade materials, yet regular tetrahedra present formidable challenge understanding their behavior as they do not tile space. Here, we report diverse supracrystals from gold nanotetrahedra including the quasicrystal (QC) dimer packing predicted more than decade ago hitherto unknown phases. We...

Crystallization is a universal phenomenon underpinning many industrial and natural processes fundamental to chemistry materials science. However, microscopic crystallization pathways of nanoparticle superlattices have been seldom studied mainly owing the difficulty real-time observation individual self-assembling nanoparticles in solution. Here, using situ electron microscopy, we directly image full self-assembly pathway from dispersed into ordered nonaqueous We show that electron-beam...
Localized surface plasmon (LSP) has been widely applied for the enhancement of fluorescence emission biosensing owing to its potential strong field enhancement. However, due small penetration depth, LSP offers limited over a whole sensor chip and, therefore, insufficient sensitivity detection biomolecules, especially large molecules. We demonstrate simultaneous excitation and propagating (PSP) on an Au nanohole array under Kretschmann configuration prostate-specific antigen with sandwich...
