Case Study

Vanadium Carbide-Doped Carbon Nanofibers for Sodium-Sulfur Batteries

Tang W, et al. Chemical Engineering Journal, 2020, 395, 124978.

A three-dimensional self-supporting structure for room-temperature sodium-sulfur (RT Na-S) batteries was successfully prepared by embedding vanadium carbide (VC) nanoparticles into carbon nanofibers. The results showed that the prepared VC-CNFs@S electrode showed a reversible capacity of 379 mAh g-1 after 2000 cycles at 0.5C, with a capacity retention rate of up to 96.2%.
Preparation of VC-CNFs and its structural advantages
· Initially, the precursor of VC-CNFs was fabricated using a straightforward one-step electrospinning method. After undergoing pre-oxidation, vanadium acetylacetonate was converted into a vanadoxy complex. Subsequently, when subjected to calcination at 800 °C, the polyacrylonitrile was carbonized into carbon nanofibers rich in nitrogen, which can potentially serve as an effective anchoring site for polysulfides. Concurrently, the reaction of the vanadoxy complex with carbon led to the formation of vanadium carbide (VC) nanoparticles.
· When utilized in Na-S batteries, the VC-CNFs host exhibit remarkable structural benefits: (a) the interconnected structure facilitates rapid electron transport throughout the electrode; (b) the porous nature of CNFs allows for physical confinement of polysulfides; (c) the VC nanoparticles function as both chemical traps, adsorbing sulfur species, and electrocatalysts, accelerating their redox reactions.

Preparation of Vanadium Carbide Coated Graphite Carbon Nitride Nanocomposites

Kokulnathan T, et al. ACS Applied Nano Materials, 2020, 3(3), 2554-2561.

In this work, a vanadium carbide supported on graphite phase carbon nitride nanosheets (VC/g-CN NSs) was developed, which can be used as an efficient electrocatalyst for the determination of furazolidone (FZD) in biological samples. The results showed that under the optimized conditions, the VC/g-CN NSs modified electrode has a wide detection range (0.004-141 μM), a very low detection limit (0.5 nM), excellent selectivity and reproducibility.
Preparation of VC/g-CN NSs nanocomposite modified electrode
· In the preparation of g-CN NSs, 2 grams of bulk g-CN were dispersed in 50 milliliters of deionized water and stirred for 15 minutes. Subsequently, 10 milliliters of sulfuric acid were added slowly to the solution. The mixture was then placed in an ultrasonic bath operating at 60 Hz with a maximum power output of approximately 60 W at room temperature. The resulting pale-yellow precipitates were washed with deionized water and ethanol, and subsequently dried in an air oven at 80 °C to form g-CN NSs.
· The electrocatalyst suspension was created by mixing 4 milligrams of VC and 3 milligrams of g-CN NSs in deionized water using ultrasonication. The homogenous suspension was then drop-casted (8.0 µL) onto the glassy carbon electrode and dried at room temperature.
