We grow nearly freestanding single-layer 1T'-WTe2 on graphitized 6H-SiC(0001) by using molecular beam epitaxy (MBE), and characterize its electronic structure with scanning tunneling microscopy / spectroscopy (STM/STS). demonstrate the existence of topological edge states at periphery WTe2 islands. Surprisingly, we also find a band gap in bulk semiconducting behaviors low temperature, which is likely resulted from an incommensurate charge density wave (CDW) transition. The realization...
The electrochemical nitrogen reduction reaction (NRR) under ambient conditions is currently attracting intense attention, but it still remains a great challenge to develop highly selective and active NRR electrocatalysts.
Interfacial electron engineering between noble metal and transition carbide is identified as a powerful strategy to improve the intrinsic activity of electrocatalytic oxygen reduction reaction (ORR). However, this short-range effect huge structural differences make it significant challenge obtain desired electrocatalyst with atomically thin layers. Here, we demonstrated combinatorial strategies fabricate heterostructure Mo2C-coupled Pd atomic layers (AL-Pd/Mo2C) by precise control...
Mechanism research of nanozymes has always been great interest since their emergence as outstanding mimics friable natural enzymes. An important but rarely mentioned issue in mechanism nanozymology is the inhibitory effect nanozymes. And conventional with various active sites hinder research, while single-atom Fe-N-C similar to enzymes exhibit structural advantages. Herein, we synthesized Fe (Fe-SANs) ultrahigh oxidase-like activity and found that a common analgesic-antipyretic drug...
Abstract The two-dimensional topological insulators host a full gap in the bulk band, induced by spin–orbit coupling (SOC) effect, together with topologically protected gapless edge states. However, it is usually challenging to suppress conductance and thus realize quantum spin Hall (QSH) effect. In this study, we find mechanism effectively conductance. By using quasiparticle interference technique scanning tunneling spectroscopy, demonstrate that QSH candidate single-layer 1 T ’-WTe 2 has...
To realize a topological superconductor is one of the most attracting topics because its great potential in quantum computation. In this study, we successfully intercalate potassium (K) into van der Waals gap type II Weyl semimetal WTe2 and discover superconducting state KxWTe2 through both electrical transport scanning tunneling spectroscopy measurements. The superconductivity exhibits an evident anisotropic behavior. Moreover, also uncover coexistence positive magnetoresistance state....
Semiconducting heterostructures have been widely applied in photocatalytic hydrogen evolution due to their variable band gaps and high energy conversion efficiency. As typical semiconducting heterostructures, ZnO/ZnS heterostructured nanorod arrays (HNRAs) obtained through a simple anion-exchange process this work. Structural characterization indicates that the nanorods (HNRs) are all composed of hexagonal wurtzite ZnO core cubic zinc-blende ZnS shell. expected, as-obtained one-dimensional...
Metallization of 1T-TaS_{2} is generally initiated at the domain boundary a charge density wave (CDW), expense its long-range order. However, we demonstrate in this study that metallization can be also realized without breaking CDW order upon surface alkali doping. By using scanning tunneling microscopy, find always persisting, and instead associated with additional in-gap excitations. Interestingly, excitation near top lower Hubbard band, contrast to conventional electron-doped Mott...
Herein, we report a novel cobalt doped transition metal carbide-based OER electrocatalyst, β-molybdenum carbide (β-Mo2C) encapsulated by nitrogen carbon framework, Co0.1-β-Mo2C@NC, which shows an unexpected onset overpotential of 200 mV and 262.2 at current density 10 mA cm-2. This strategy doping reduces the amount cobalt, increases active sites as well; furthermore, introduction molybdenum enhances stability catalyst.
Ammonia (NH3), which serves as a fertilizer supply, is struggling to satisfy the ever-growing population requirements over world. The electrocatalytic nitrogen reduction NH3 production highly desired but shows extremely poor activity and selectivity of reported electrocatalysts. In this work, we rationally design novel Rh atomic layer-decorated SnO2 heterostructure catalyst through interfacial engineering strategy, simultaneously achieving highest yield rate (149 μg h-1 mgcat-1) Faradaic...
A chemical fixation strategy originating from single-atom-anchoring with metal–organic frameworks as a carrying matrix was proposed for solid-state electrochemiluminescence (ECL). Herein, UiO-67(N) the exposure of 2,2′-bipyridine (bpy) ligands could coordinate Ru2+ to form local structure [Ru(bpy)3]2+ (Ru-UiO). The influence steric effect induced different Ru sources discussed. as-obtained Ru-UiO exhibits high ECL intensity and outstanding stability in presence coreactant at low...
The ever-increasing attention on the highly sensitive biosensors pushes people to explore functional nanomaterials for signal amplification. To endow inert metal–organic frameworks (MOFs) with enzyme mimicking activity, a simple strategy of introducing Cu2+ via coordination 2,2′-bipyridine ligands Zr-MOF, just like "Midas touch," is proposed. More details environment Cu active sites in Zr-MOF-Cu are disclosed electron paramagnetic resonance and synchrotron-radiation-based X-ray absorption...
Abstract A facile method for the quantitative preparation of silver dibenzo‐fused corrole Ag‐1 is described. In contrast to saddle conformation resolved by single‐crystal X‐ray analysis Ag‐1, it adopts an unprecedented domed geometry, with up and down orientations, when adsorbed on Ag(111) surface. Sharp Kondo resonances near Fermi level, both at ligand center were observed cryogenic STM, relatively high temperature (172 K), providing evidence a non‐innocent Ag II ‐corrole .2− species....
A bifunctional bio-photoelectrochemical cell based on a biotic/abiotic hybrid strategy was fabricated as “trading” platform for renewable energy conversion and H 2 O output under mild pH conditions.
Stanene has been predicted to be a two-dimensional topological insulator (2DTI). Its low-buckled atomic geometry and the enhanced spin-orbit coupling are expected cause prominent quantum spin hall (QSH) effect. However, most of experimentally grown stanene date displays metallic state without real gap, possibly due chemical with substrate stress applied by substrate. Here,we demonstrate an efficient way tuning buckling in open topologically nontrivial energy gap. Via growth kinetics, we...
