This invention discloses a method for preparing a high-strength, high-thermal-conductivity Mg-Zn-Cu-Mn magnesium alloy, belonging to the field of magnesium alloy preparation technology. Metal raw materials are prepared according to the atomic percentage ratio of each constituent element in the Mg-3Zn-3Cu-xMn alloy (0≤x≤1). Then, alloy melting, homogenization treatment, and hot extrusion deformation are performed sequentially. The extrusion temperature is 260-270℃, and the extrusion speed is 0.3-0.6 mm / s. This invention achieves homogeneous dispersion of Mn to cluster precipitation in the Mg-Zn-Cu magnesium alloy through Mn alloying modification treatment. When 0.6 wt.% Mn is added, the alloy exhibits the best thermal conductivity and tensile strength. This invention refines the grain size of the Mg-Zn-Cu-Mn magnesium alloy and eliminates some casting defects, thereby further improving the alloy's strength and thermal conductivity.

This invention relates to a vacancy-controlled manganese selenide-molybdenum selenide-sulfurite heterojunction catalyst, its preparation method, and its applications. The invention first prepares nanoparticle-sized MnSe, then reacts the MnSe with sodium molybdate, Se powder, and other raw materials via a hydrothermal reaction to obtain the manganese selenide-molybdenum selenide-sulfurite heterojunction catalyst.
