    Application
    The purpose of Single Layer WS2 Dispersion (C: 0.1mg/ml, solvent: water) is to leverage the unique properties of tungsten disulfide (WS2) at the molecular level for various advanced applications. This dispersion features single-layer WS2, which possesses a direct bandgap of 2.1 eV, making it highly effective in a range of technological and industrial fields. Due to its distinct electron configuration and high specific surface area, it is particularly advantageous as a catalyst in hydrogen evolution reactions (HERs), enhancing efficiency in energy storage devices and electrodes. Additionally, the dispersion holds promise in applications combating electromagnetic pollution due to its tunable electromagnetic absorption. WS2's capabilities extend further into the realm of medical applications, where it serves as a potent agent in photothermal therapy for cancer treatment, absorbing NIR light and converting it into heat for targeted cell ablation. The dispersion's composition in water facilitates its integration into various formulations, maximizing its use in cutting-edge material science and engineering projects.
