Intrinsically inferior electrocatalytic activity of NiFe layered double hydroxides (LDHs) nanosheets is considered as a limiting factor to inhibit the properties for oxygen evolution reaction (OER). Proper defect engineering tune surface electronic configuration electrocatalysts may significantly improve intrinsic activity. In this work, selective formation cation vacancies in LDHs successfully realized. The as-synthesized LDHs-VFe and LDHs-VNi show excellent OER, mainly attributed...
Despite wide applications of bimetallic electrocatalysis in oxygen evolution reaction (OER) owing to their superior performance, the origin improved performance remains elusive. The underlying mechanism was explored by designing and synthesizing a series stable metal-organic frameworks (MOFs: NNU-21-24) based on trinuclear metal carboxylate clusters tridentate ligands. Among examined MOFs, NNU-23 exhibits best OER performance; particularly, compared with monometallic all MOFs display...
Sb-based nanocomposites are attractive anode materials for batteries as they exhibit large theoretical capacity and impressive working voltage. However, tardy potassium ion diffusion characteristics, unstable Sb/electrolyte interphase, huge volume variation pose a challenge, hindering their practical use potassium-ion (PIBs). Now, simple robust strategy is presented uniformly impregnating ultrasmall Sb nanocrystals within carbon nanofibers containing an array of hollow nanochannels (denoted...
Abstract The oxygen evolution reaction (OER) is an ideal model to study the relationship between activity and surface properties of catalysts. Defect engineering has been extensively developed tune electrocatalytic for OER. Compared anion vacancies in metal oxides, cation are more challenging selectively generate, insight into structure vacancies‐rich catalysts lacked. Herein, using SnCoFe perovskite hydroxide as a precursor, abundant Sn on were preferentially produced by Ar plasma. could be...
Electrocatalysis is dominated by reaction at the solid-liquid-gas interface; surface properties of electrocatalysts determine electrochemical behavior. The charge active sites on catalysts modulate adsorption and desorption intermediates. However, there no direct evidence to bridge catalytic activity sites. Defects (active sites) were created a HOPG (highly oriented pyrolytic graphite) that broke intrinsic sp2 -hybridization graphite plasma, inducing localization onto defective sites, as...
Direct production of H2 from photocatalytic water splitting is a potential solution to environmental pollution and energy crisis, tremendous efforts have been made seek efficient photocatalysts that can split pure (pH = 7) under visible light irradiation. Herein, by means systematic density functional theory (DFT) computations, we demonstrated the two-dimensional (2D) PdSeO3 monolayer promising candidate. The mechanical exfoliation its bulk phase experimentally feasible due rather small...

To meet the requirements for industrial water splitting to generate hydrogen, it is urgent, but still quite challenging develop highly active and stable electrocatalysts large-current-density hydrogen evolution reaction (HER). Herein, Ru-incorporated NiSe2 (Ru-NiSe2 ) was designed synthesized. The introduction of Ru results in formation hierarchically structured Ru-NiSe2 with large electrochemical surface area, well-modified electronic structure. As expected, as-fabricated displays...
By means of comprehensive density functional theory (DFT) computations, we designed a new two-dimensional (2D) structure silicon, namely, tetra-silicene. In tetra-silicene, each silicon atom binds with four neighboring Si atoms to form 2D network composed only tetragons. Our DFT computations demonstrate that tetra-silicene is rather high experimental feasibility, as indicated by its considerable cohesive energy, all positive modes in the phonon spectrum, and well maintained after 10 ps...
