High-entropy alloys (HEAs) with unique physicochemical properties have attracted tremendous attention in many fields, yet the precise control on dimension and morphology at atomic level remains formidable challenges. Herein, we synthesize PtRuNiCoFeMo HEA subnanometer nanowires (SNWs) for alkaline hydrogen oxidation reaction (HOR). The mass specific activities of SNWs/C reach 6.75 A mgPt+Ru-1 8.96 mA cm-2, respectively, which are 2.8/2.6, 4.1/2.4, 19.8/18.7 times higher than those NPs/C,...

The ultrafast growth of high‐quality uniform monolayer WSe 2 is reported with a rate ≈26 µm s −1 by chemical vapor deposition on reusable Au substrate, which ≈2–3 orders magnitude faster than those most 2D transition metal dichalcogenides grown nonmetal substrates. Such allows for the fabrication millimeter‐size single‐crystal domains in ≈30 and large‐area continuous films ≈60 s. Importantly, shows excellent crystal quality extraordinary electrical performance comparable to mechanically...
A Pt 1 /(Co,Ni)(OH) 2 /C single-atom electro-catalyst efficiently splits water for H generation, via balanced water-dissociation and -formation steps from the synergistic effect of surface-defective (Co,Ni)(OH) electronically tuned sites.
High-entropy alloys (HEAs) have been attracting extensive research interests in designing advanced nanomaterials, while their precise control is still the infancy stage. Herein, we reported a well-defined PtBiPbNiCo hexagonal nanoplates (HEA HPs) as high-performance electrocatalysts. Structure analysis decodes that HEA HP constructed with PtBiPb medium-entropy core and PtBiNiCo high-entropy shell. Significantly, HPs can reach specific mass activities of 27.2 mA cm-2 7.1 A mgPt-1 for formic...
Designing platinum (Pt)-based formic acid oxidation reaction (FAOR) catalysts with high performance and selectivity of direct dehydrogenation pathway for fuel cell (DFAFC) is desirable yet challenging. Herein, we report a new class surface-uneven PtPbBi/PtBi core/shell nanoplates (PtPbBi/PtBi NPs) as the highly active selective FAOR catalysts, even in complicated membrane electrode assembly (MEA) medium. They can achieve unprecedented specific mass activities 25.1 mA cm-2 7.4 A mgPt-1 FAOR,...
Methanol (ME) is a liquid hydrogen carrier, ideal for on-site-on-demand H2 generation, avoiding its costly and risky distribution issues, but this "ME-to-H2" electric conversion suffers from high voltage (energy consumption) competitive oxygen evolution reaction. Herein, we demonstrate that synergistic cofunctional Pt1Pdn/(Ni,Co)(OH)x catalyst with Pt single atoms (Pt1) Pd nanoclusters (Pdn) anchored on OH-vacancy(VOH)-rich (Ni,Co)(OH)x nanoparticles create triadic active sites, allowing...
