Extended Data Fig. 10: Morphology diagram of HEA nanomaterials.
From: Isothermal solidification for high-entropy alloy synthesis
STEM images show the diverse morphology of HEAs. a, To synthesize nanoparticles in panel (a), we utilize sphere liquid Ga (marked with red outline) or liquid Ga alloy (marked with yellow outline) as precursors. Additionally, we introduce HCl into the metal salt solution to eliminate the surface oxide of the Ga and Ga alloy particles. The reaction temperature with the red outline is 30 °C and the reaction temperature with yellow outline is room temperature. b, d, f, The synthesis conditions for the particles depicted in panel (b), (d), and (f) mirror those in panel (a), but with elevated reaction temperatures of 40 °C, 60 °C, and 80 °C. c, We employ spherical shape (marked with indigo outline), irregular shape (marked with green outline), and two-dimensional-film (marked with white outline) liquid Ga/Ga alloy precursors, without the addition of HCl in the metal salt solution, and the reaction temperature is 60 °C. e, For HEA synthesis, we use two-dimensional films of liquid Ga/Ga alloy precursors and the reaction temperature is 80 °C.
