Low‐Temperature Atomic Layer Deposition Synthesis of Vanadium Sulfide (Ultra)Thin Films for Nanotubular Supercapacitors
Abstract
<jats:p>Herein, the synthesis of vanadium sulfide (V<jats:sub><jats:italic>x</jats:italic></jats:sub>S<jats:sub><jats:italic>y</jats:italic></jats:sub>) by atomic layer deposition (ALD) based on the use of tetrakis(dimethylamino) vanadium (IV) and hydrogen sulfide is presented for the first time. The (ultra)thin films V<jats:sub><jats:italic>x</jats:italic></jats:sub>S<jats:sub><jats:italic>y</jats:italic></jats:sub> are synthesized in a wide range of temperatures (100–225 °C) and extensively characterized by different methods. The chemical composition of the V<jats:sub><jats:italic>x</jats:italic></jats:sub>S<jats:sub><jats:italic>y</jats:italic></jats:sub> (ultra)thin films reveals different vanadium oxidation states and sulfur‐based species. Extensive X‐ray photoelectron spectroscopy analysis studies the effect of different ALD parameters on the V<jats:sub><jats:italic>x</jats:italic></jats:sub>S<jats:sub><jats:italic>y</jats:italic></jats:sub> chemical composition. Encouraged by the rich chemistry properties of vanadium‐based compounds and based on the variable valences of vanadium, the electrochemical properties of ALD V<jats:sub><jats:italic>x</jats:italic></jats:sub>S<jats:sub><jats:italic>y</jats:italic></jats:sub> (ultra)thin films as electrode material for supercapacitors are further explored. Thereby, nanotubular composites are fabricated by coating TiO<jats:sub>2</jats:sub> nanotube layers (TNTs) with different numbers of V<jats:sub><jats:italic>x</jats:italic></jats:sub>S<jats:sub><jats:italic>y</jats:italic></jats:sub> ALD cycles at low temperature (100 °C). Long‐term cycling tests reveal a gradual decline of electrochemical performance due to the progressive V<jats:sub><jats:italic>x</jats:italic></jats:sub>S<jats:sub><jats:italic>y</jats:italic></jats:sub> thin films dissolution under the experimental conditions. Nevertheless, V<jats:sub><jats:italic>x</jats:italic></jats:sub>S<jats:sub><jats:italic>y</jats:italic></jats:sub>‐coated TNTs exhibit significantly superior capacitance properties as compared to the blank counterparts. The enhanced capacitance properties exhibited are derived from the presence of chemically stable and electrochemically active S‐based species on the TNTs surface.</jats:p>
