Co3O4 with a high theoretical capacitance has been widely recognized as promising electrode material for supercapacitor, but its poor electrical conductivity and stability limit practical applications. Here, we developed an effective synthetic route to synthesize one-dimensional (1D) porous ZnO/Co3O4 heterojunction composites. Benefiting from the heterostructure promote charge transfer protect corrosion 1D structure improve ion diffusion prevent structural collapse in discharge process,...
A facile hydrothermal method combined with a mild ultrasonic means has been developed for the fabrication of magnetically recyclable thin-layer MnO2 nanosheet-coated Fe3O4 nanocomposite. The photocatalytic studies suggest that MnO2/Fe3O4 nanocomposite shows excellent efficiency and stability simultaneously degradation methylene blue under UV–vis light irradiation. Moreover, its good acid resistance stable recyclability are very important future practical application as photocatalyst....
Electrode materials for high-rate supercapacitors are greatly desired. Among actively studied electrode materials, phosphide compounds with metallic features recognized as such promising supercapacitor materials. In this work, considering the benefits of multimetal redox centers and superior electrical conductivity ternary nickel–cobalt metal phosphides improving performance, urchin-like hollow spheres were prepared a mild hydrothermal method followed by phosphorization. The formation...
The prepared monodisperse Ni@Pd3 core–shell nanoparticles with a Pd-enriched surface exhibited Pt-like ORR electrocatalytic activity and long durability under both acidic alkaline conditions.
The topological characteristics, including invariant orders, band inversion, and the edge mode (TEM) in photonic insulators, have been widely studied. Whether people can take advantage of intriguing modes simple one-dimensional systems to implement some practical applications is an issue which are increasingly concerned about. In this work, based on a dimer chain composed ultra-subwavelength resonators, we verify experimentally that TEM effective second-order parity-time (PT) system immune...
Fe3O4 nanoparticles (NPs) with sizes of ca 5.3, 6.6, and 9.8 nm can be successfully loaded on the surface CoSe2-DETA hybrid nanobelts via a facile thermal reduction process in polyol solution. The resulting multifunctional nanocomposites are superparamagnetic at room temperature. Most interestingly, electrocatalytic activity for O2 reaction (ORR) constructed Fe3O4-decorated CoSe2 yield decent enhancement compared original catalysts, i.e., onset potential current density show 1.01 mA cm−2...
With the rapid global urbanization, today's cities are facing an increasing pressure for treatment of both domestic and industrial wastewaters. In this work, a proof-of-concept "treating wastewater using sludge originating from urban pollution control" was proposed. After one-step pyrolysis excess treatment, metal–carbon composite catalyst with high H2O2-producing capacity (432 mg/h/g) successfully synthesized. By application prepared material as cathode in electro-Fenton system, phenol (40...
Carbon-based materials are recognized as promising candidates for pollutant degradation because of their environmental benignity. Massive and cost-effective production efficient recovery carbon-based catalysts crucial to apply this technology. However, various nanostructured carbons with different dimensions usually utilized precursors while not considering complex preparation procedures the high costs ingredients. Moreover, catalyst separation given sufficient attention. In work, a calcium...
Electron doping by hydrogenation can reversibly modify the electrical properties of complex oxides. We show that in order to realize large, fast, and reversible response hydrogen, it is important consider both electron configuration on transition metal 3d orbitals, as well thermodynamic stability nickelates. Specifically, large doping-induced resistivity modulations ranging several orders magnitude change are only observed for rare earth nickelates with small ionic radii A-site, which case...
Abstract Track irregularity from rail alternate side wear is manifested as uneven waveforms alternating in the left and right rails with equal intervals, which will cause carbody sway behaviour of railway vehicles greatly influences passenger comfort. In this work, mechanism due to track possible solutions issue were studied by field testing numerical calculation approaches. First, an urban transit train introduced full-scale tests, through characterized formatted are presented. Then,...

The catalytic properties of ultrafine metal nanoparticles (NPs) are usually limited by their dispersion NPs; support is thus needed for NPs. However, single-dimensional supports cannot exhibit a superior performance because the ease aggregation. In this work, we design hierarchical structure comprising 0D nickel (Ni) NPs, flower-like 3D MoS2 nanosheets (NSs), and 2D graphene performance. design, NSs were backbone growth Ni NPs was used to hamper aggregation deformation NSs. well-dispersed...
