High-Yield WS₂ Synthesis through Sulfurization in Custom-Modified Atmospheric Pressure Chemical Vapor Deposition Reactor, Paving the Way for Selective NH₃ Vapor Detection.

ABSTRACT: Nanostructured transition metal dichalcogenides have garnered significant research interest for physical and chemical sensing applications due to their unique crystal structure and large effective surface area. However, the high-yield synthesis of these materials on different substrates and in nanostructured films remains a challenge that hinders their real-world applications. In this work, we demonstrate the synthesis of two-dimensional (2D) tungsten disulfide (WS₂) sheets on a hundred-milligram scale by sulfurization of tungsten trioxide (WO₃) powder in an atmospheric pressure chemical vapor deposition reactor. The as-synthesized WS₂ powders can be formulated into inks and deposited on a broad range of substrates using techniques like screen or inkjet pri
