α-Fe2O3 nanotubes that can be used as chemical sensors (see Figure) are fabricated by a novel carbon nanotube (CNT) templated synthesis. CNTs coated with continuous layer of Fe2O3 nanoparticles the decomposition Fe(NO3)3 in supercritical CO2/ethanol solution. Subsequent removal gives highly sensitive to H2S, which makes them attractive materials for chemiluminescent H2S sensors.
Lithium–sulfur (Li–S) batteries are considered promising energy storage technologies due to their high density and environmental friendliness. However, the unsatisfactory electrochemical performance mainly caused by dissolution shuttling of polysulfides limits application. Herein, a multifunctional separator, i.e., sodium alginate (SA) fiber membrane with in situ loading ZIF-67 attached on polyacrylonitrile (PAN) matrix (ZIF-67/SA-PAN), is developed for Li–S batteries. On basis synergistic...
Passivation of the Mg anode surface in conventional electrolytes constitutes a critical issue for practical batteries. In this work, perfluorinated tert-butoxide magnesium salt, Mg(pftb)2 , is codissolved with MgCl2 tetrahydrofuran (THF) to form an all-magnesium salt electrolyte. Raman spectroscopy and density function theory calculation confirm that [Mg2 Cl3 ·6THF]+ [Mg(pftb)3 ]- main electrochemically active species The proper lowest unoccupied molecular orbital energy level anion enables...
Seeking an optimal catalyst to accelerate conversion reaction kinetics of room-temperature sodium-sulfur (RT Na-S) batteries is crucial for improving their electrochemical performance and promoting the practical applications. Herein, theoretical calculations interfacial interactions catalysts polysulfides in terms surface adsorption state, ions migration, electronic concentration around Fermi level are systematically proposed as guiding principles selection RT Na-S batteries. As a case, MoN...
Abstract The separators used in lithium‐sulfur (Li–S) batteries play a crucial role their cycling performance and safety. Current commercial lack the ability to efficiently regulate polysulfide shuttling are prone thermal runaway at high temperatures. Recent studies have shown that multifunctional can boost electrochemical safety of Li–S batteries. Metal–organic frameworks (MOFs) emerged as promising materials for modifying due large specific surface areas highly ordered tunable nanopores....
Abstract Fiber‐supercapacitors (FSCs) are promising energy storage devices that can complement or even replace microbatteries in miniaturized portable and wearable electronics. Currently, a major challenge for FSCs is achieving ultrahigh volumetric power densities simultaneously, especially when the charge/discharge rates exceed 1 V s −1 . Herein, an Au‐nanoparticle‐doped‐MnO x @CoNi‐alloy@carbon‐nanotube (Au–MnO @CoNi@CNT) core/shell nanocomposite fiber electrode designed, aiming to boost...
MXene is a two-dimensional nanostructured transition metal carbon/nitride and carbon nanotubes (CNTs) are one-dimensional graphitized material, which widely exploited for their large specific surface excellent electrical conductivity, but the easy aggregation limits performance.
