An activity lift for platinum Platinum is an excellent but expensive catalyst the oxygen reduction reaction (ORR), which critical fuel cells. Alloying with other metals can create shells of on cores less metals, increases its surface exposure, and compressive strain in layer also boost (see Perspective by Stephens et al. ). Bu produced nanoplates—platinum-lead covered shells—that were tensile strain. These nanoplates had high stable ORR activity, theory suggests arises from optimizing...
Electrochemical conversion of CO2 into valued products is one the most important issues but remains a great challenge in chemistry. Herein, we report novel synthetic approach involving prolonged thermal pyrolysis hemin and melamine molecules on graphene for fabrication robust efficient single-iron-atom electrocatalyst electrochemical reduction. The single-atom catalyst exhibits high Faradaic efficiency (ca. 97.0 %) CO production at low overpotential 0.35 V, outperforming all Fe-N-C-based...

Abstract Among van der Waals layered ferromagnets, monolayer vanadium diselenide (VSe 2 ) stands out due to its robust ferromagnetism. However, the exfoliation of VSe is challenging, not least because flake extremely unstable in air. Using an electrochemical approach with organic cations as intercalants, 1T‐VSe flakes are successfully obtained from bulk crystal at high yield. Thiol molecules further introduced onto surface passivate exfoliated flakes, which improves air stability for...

The construction of an efficient oxygen reduction reaction and evolution (ORR/OER) bifunctional electrocatalyst is great significance but still remains a giant challenge for high-performance metal-air batteries. In this study, uniform FeS/Fe3C nanoparticles embedded in porous N,S-dual doped carbon honeycomb-like composite (abbr.

Controllable synthesis of single atom catalysts (SACs) with high loading remains challenging due to the aggregation tendency metal atoms as surface coverage increases. Here we report graphene supported cobalt SACs (Co1/G) a tuneable by atomic layer deposition. Ozone treatment support not only eliminates undesirable ligands pre-deposited precursors, but also regenerates active sites for precise tuning density Co atoms. The Co1/G demonstrate exceptional activity and selectivity hydrogenation...
Hydrazine-reduced graphite oxide and graphene were synthesized to compare their performances as anode materials in lithium-ion batteries sodium-ion batteries. Reduced inherits the layer structure of graphite, with an average spacing between neighboring layers (d-spacing) 0.374 nm; this exceeds d-spacing (0.335 nm). The larger provides wider channels for transporting lithium ions sodium material. We showed that reduced can reach a specific capacity 917 mA h g-1, which is about three times 372...

Abstract Nanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within ultrathin thickness, emerge miniaturized, ultracompact and kaleidoscopic optical vortex generators. However, it is often required to segment or interleave independent sub-array metasurfaces multiplex vortices in a single nano-device, which turn affects the device’s compactness channel capacity. Here, inspired by phyllotaxis patterns pine cones sunflowers, we theoretically prove experimentally...
Deuterium labeling is of great value in organic synthesis and the pharmaceutical industry. However, state-of-the-art C-H/C-D exchange using noble metal catalysts or strong bases/acids suffers from poor functional group tolerances, selectivity lack scope for generating molecular complexity. Herein, we demonstrate deuteration halides heavy water as reagent porous CdSe nanosheets catalyst. The mechanism involves generation highly active carbon deuterium radicals via photoinduced electron...
The ability to tune both local and global environments of a single-metal active center on support is crucial for the development highly robust efficient single-atom electrocatalysts (SAECs) that can surmount thermodynamic kinetic constraints in electrocatalysis.
