The flower-like MoS2/BiVO4 composite with heterojunction has been successfully fabricated by a two-step approach. A possible formation mechanism of this heterostructure was investigated. calculated valence band offset (VBO) and conduction (CBO) showed that the VBO CBO are 1.4 0.3 eV, respectively, implying well-defined staggered type II alignment. photodegradation methylene blue (MB) adopted to assess photocatalytic ability pristine MoS2 BiVO4 as well composites. It exhibited structures...
Molybdenum disulfide (MoS2) has attracted extensive attention as a non-noble metal electrocatalyst for hydrogen evolution reaction (HER). Controlling the skeleton structure at nanoscale is paramount to increase number of active sites surface. However, hydrothermal synthesis favors presence basal plane, limiting efficiency catalytic reaction. In this work, perfect hollow MoS2 microspheres capped by nanospheres (hH-MoS2) were obtained first time, which creates an opportunity improving HER...
Rational architecture design of the artificial protective layer on zinc (Zn) anode surface is a promising strategy to achieve uniform Zn deposition and inhibit uncontrolled growth dendrites. Herein, red phosphorous-derived combined with conductive N-doped carbon framework designed dendrite-free deposition. The Zn-phosphorus (ZnP) solid solution alloy formed during plating. Meanwhile, dynamic evolution mechanism ZnP successfully revealed. concentration gradient electrolyte electrode can be...
The zinc l -cysteine functional layer was constructed by in situ etching Zn anode 1 M solution. This not only improves the hydrophobicity and corrosion resistance of anode, but also guides uniform deposition.
Aqueous metal-ion batteries are considered next-generation energy storage devices with improved safety. However, they suffer from sluggish kinetics and side reactions. This work presents a zinc-ion encapsulation strategy based on the poloxamer pre-solvation sheath for realization of efficient zinc anode–electrolyte interfaces. The poloxamers can reversibly self-assemble into by electron-donating effect effectively shield ions surrounding water. also lowers activation desolvation, endowing...
Abstract The mechanically and electrochemically stable ionically conducting solid electrolyte interphase (SEI) is important for the stabilization of metal anodes. Since SEIs are originally absent in aqueous zinc batteries (AZMBs), it very challenging to suppress water‐induced side reactions dendrite growth Zn anodes (ZMAs). Herein, a gradient‐structured robust gradient SEI, consisting B,O‐inner F,O‐exterior layer, situ formed by hydrated eutectic homogeneous reversible deposition,...
The molecularly engineered multifunctional additive of H-SU, which effectively modulates both solvated and interfacial structures, was chosen from a family imide derivatives for practical aqueous Zn metal full cells.
Abstract The undesirable dendrite growth induced by non-planar zinc (Zn) deposition and low Coulombic efficiency resulting from severe side reactions have been long-standing challenges for metallic Zn anodes substantially impede the practical application of rechargeable aqueous metal batteries (ZMBs). Herein, we present a strategy achieving high-rate long-cycle-life anode patterning foil surfaces endowing Zn-Indium (Zn-In) interface in microchannels. accumulation electrons microchannel...
