Three-dimensional (3D) lithiophilic host is one of the most effective ways to regulate Li dendrites and volume change in working metal anode. The state-of-the-art 3D hosts are facing main challenge that layer would melt or fall off high-temperature environment when using thermal infusion method. Herein, a porous CuZn alloy containing anchored Zn sites employed prestore strategy, composite thus fabricated. Benefiting from with strong adsorption capacity Li, which based on analyses nucleation...
Two nanostructured proton-containing δ-MnO<sub>2</sub> (H-δ-MnO<sub>2</sub>) materials were synthesized through proton exchange for K-containing (K-δ-MnO<sub>2</sub>) nanosheets and nanoparticles prepared by the hydrothermal homogeneous precipitation method solid-state reaction.
Micro silicon is considered as the most prospective anode material for large-scale application of lithium-ion batteries (LIBs) due to its low production cost and diverse accessibilities. However, micro anodes coupled with conventional binders generally show poor performances in LIBs. Therefore, developing new high performance LIBs highly desirable. In this work, we report first lignin-derived water-soluble binder (lignin-graft-sodium polyacrylate, PAL–NaPAA) anodes. The PAL–NaPAA obtained...
The lithium (Li)-metal anode offers a promising solution for high-energy-density lithium-metal batteries (LMBs). However, the significant volume expansion of Li metal during charging results in poor cycling stability as result dendritic deposition and broken solid electrolyte interphase. Herein, facile one-step roll-to-roll fabrication zero-volume-expansion Li-metal-composite (zeroVE-Li) is proposed to realize LMBs with outstanding electrochemical mechanical stability. zeroVE-Li possesses...
Amino-functionalized multi-walled carbon nanotubes (NH2-MWCNTs) for the removal of methyl orange (MO) from aqueous solution were prepared first time using 1,6-hexanediamine by a simple one-pot process at 198 °C 8 h. The resulting materials characterized different techniques, such as TEM, FTIR, XPS, Raman, elemental analysis and BET surface area measurement. Experimental results indicated that amount bound on MWCNTs was estimated to be around 5 wt% showed an excellent adsorption capacity...
Effective removal of heavy metal ions from wastewater is one the important environment issues.
Lithium–sulfur batteries are highly appealing as high-energy power systems and hold great application prospects for flexible wearable electronics. However, the easy formation of lithium dendrites, shuttle effect dissolved polysulfides, random deposition insulating sulfides, poor mechanical flexibility both electrodes seriously restrict utilization stabilities sulfur practical applications. Herein, we present a cooperative strategy employing silk fibroin/sericin to stabilize lithium–sulfur...
A novel selective fluorescent chemosensor L based on rhodamine B derivative has been designed and synthesized to optically detect Cu2+ S2− in aqueous buffer solution. The fluorescence of was excited by with a 1 : binding ratio, could be used as “turn-on” type sensor. Otherwise, the emission band would undergo slight red-shift. Once Cu2+, copper complex can exhibit high selectivity for S2−. Upon addition color changes from colorless pink. Additionally, resulting pink solution immediately upon...
A highly enantioselective [4 + 2] cycloaddition of allenoates with 2-olefinic benzofuran-3-ones catalyzed by (DHQD)2AQN, which allowed the synthesis optically active dihydropyran-fused benzofurans, was developed.
The use of carbon-based catalysts to catalyze the hydrothermal conversion biomass and its derived carbohydrates produce platform compounds such as 5-(hydroxymethyl)furfural (HMF), levulinic acid (LA), furfural (FF) has a long history. excellent thermal stability chemical activity low preparation cost make them develop rapidly in catalytic conversion, which is core attention review. Carbon are divided into sulfuric acid-based carbon catalysts, phosphoric metal-supported other types study...
δ-MnO2/o-MWCNTs were synthesized by coating MnO2 spontaneously on oxidized multi-walled carbon nanotubes via simple immersion of the o-MWCNTs into KMnO4 solution. This catalyst comprising outer region catalytic and inner highly conductive enhanced photocatalytic water oxidation activity.
Nitrogen-doped carbon anode materials have been prepared by a hard-template (SiO2 nanoparticles) method, in which alkali lignin-derived azo polymer (AL-azo-NO2) was used as low-cost precursor. The as-prepared N-doped show honeycomb-like morphology with uniform nanopores. These are able to reversibly insert Na+ ions and promising cycling performance. In particular, the porous material larger surface area pore volume delivers higher initial capacity of 205 mAh g−1 voltage range 0.01–2 V at 50...
