Sep 15, 2014 · This paper describes the development of synthetic protocols for producing colloidal WS 2 monolayers, presenting not only the usual semiconducting prismatic 2H-WS 2 structure but also the less common distorted octahedral 1T-WS 2 …

Jan 1, 2023 · In this work, the 2H-WS 2 nanosheets are prepared by an improved CVD method using a combination design of two tubes closed at one end. By optimizing growth conditions, the large-area 2H-WS2 nanosheets with different thickness and morphologies are obtained.

Feb 10, 2024 · In this study, through systematic investigation and theoretical simulation of phase change of 2M WS 2, we demonstrate that ultrathin 2M WS 2 has significantly higher intrinsic thermal...

Feb 21, 2019 · The obtained W/WS 2−x electrocatalysts are evaluated experimentally and theoretically to arrive at a better understanding of how to modify the inherently inert 2H-WS 2 for more efficient HER.

Oct 2, 2023 · Here, this issue is addressed by evolving a dual-phase 1T-2H WS 2 heterostructure that combines two different phases directly on the current collector. The resulting material demonstrated a 2D transformable phase structure, large interlayer distance, and highly exposed edge-active sites.

Jan 8, 2018 · We show that LPE–2H–WS 2 undergoes a spontaneous reaction with aqueous AuCl 3 to form AuNPs that predominantly nucleate at edge sites. The observation of the covalent Au–S bond for the...

Nov 15, 2024 · Here we achieve phase-switchable preparation of 2D transition metal dichalcogenides using an electrochemical lithium-ion intercalation-based exfoliation strategy by controlling the discharge...

Jul 28, 2017 · We successfully synthesized WS 2 nanosheets of regular hexagonal symmetry with a 2H → 1T phase transition. This represents a novel method of producing 1T-WS 2 nanosheets from bulk 2H-WS 2 without compromising on its electrocatalytic properties.

Feb 1, 2023 · Transition metal dichalcogenides have attracted significant attention in green energy production and storage due to their two-dimensional structure and tunable electronic properties. In this study, four phases of WS2, including 2H, 1H, 1 T’, and 1 T, were studied using Density Functional Theory (DFT) and Machine Learning (ML).

Oct 8, 2014 · This paper describes the development of synthetic protocols for producing colloidal WS2 monolayers, presenting not only the usual semiconducting prismatic 2H-WS2 structure but also the less common distorted octahedral 1T-WS2 structure, which exhibits metallic behavior.
