Disordered surface formation of WS2 via hydrogen plasma with enhanced anode performances for lithium and sodium ion batteries. - In: Sustainable energy & fuels, ISSN 2398-4902, Bd. 3 (2019), 3, S. 865-874

Transition metal dichalcogenide (TMD) nanoparticles have attracted much attention recently for lithium and sodium ion batteries (LIBs and SIBs) due to their layered structures, which act as host lattices when reacting with ions to yield intercalation compounds. In the present article, WS2 nanoparticles are modified through hydrogen plasma treatment, and the hydrogenated WS2 (H-WS2) nanoparticles demonstrate clearly enhanced electrochemical performance as an anode material for LIBs and SIBs. H-WS2 nanoparticles are fabricated via hydrogen plasma treatment at 300 ˚C for 2 hours. A transmission electron microscopy (TEM) investigation shows that the nanoparticles have a disordered surface layer with a thickness of around 2.5 nm after the treatment, and this is confirmed by the results of Raman spectroscopy. A shift in the X-ray photoelectron spectroscopy (XPS) peaks indicates that the structural surface disorders are incorporated in the crystalline structure. The H-WS2 based LIBs and SIBs possess significantly higher specific capacities at different current densities. In addition, electrochemical impedance spectroscopy (EIS) reveals a drastic decrease in the charge-transfer resistance for both the LIBs and SIBs, which implies that the plasma hydrogenated electrode is more favorable for electron transportation during the electrochemical process. The improved rate performance of H-WS2 when applied to both LIBs and SIBs can be attributed to the reduced charge-transfer resistivity at the disordered surface layer and the improved electronic conductivity due to the disordered surface in the crystalline structure.

Plasma hydrogenated TiO2/nickel foam as an efficient bifunctional electrocatalyst for overall water splitting. - In: ACS sustainable chemistry & engineering, ISSN 2168-0485, Bd. 7 (2019), 1, S. 885-894

Electrochemical water splitting is one of the most efficient technologies for hydrogen production and fabrication of low-cost, robust, and highly active electrocatalysts. It is attractive because replacing noble metal-based materials is a key issue in current catalysis research. By using H2 plasma treatment, the TiO2/nickel foam composite is converted to be an efficient bifunctional electrocatalyst toward both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in the alkaline electrolyte. The investigation reveals the existence of abundant oxygen vacancies of TiO2, which might lead to the dramatic improvement of electrical conductivity and faster charge transfer rate; also, density functional theory (DFT) calculations suggest that the oxygen vacancies activate surrounding surface lattice oxygen to induce favorable reactive-intermediate adsorption energy of TiO2 for hydrogen evolution and adjust the strength of the chemical bonds between the TiO2 surface and reactive intermediates to more favorable values, inducing a lower energy barrier for oxygen evolution. The finding confers a unique function to TiO2 that is different from its widely accepted role as an electrocatalytically inert semiconductor material, suggesting the H2 plasma treated TiO2/nickel foam could be a bifunctional electrocatalyst for overall water splitting.
