Embodiment 1
[0028] Example 1 SiO 2 Coated Sn 0.99 Cu 0.01 Preparation of Alloy Powder as Catalyst Carrier with Temperature Regulating Function
[0029] 1) Weigh 30g of pre-prepared LiNO 3 -NaNO 3 -KNO 3 eutectic mixture (melting point about 120 °C) and 6 g of Sn prepared by high-temperature melting 0.99 Cu 0.01 alloy;
[0030] 2) LiNO 3 -NaNO 3 -KNO 3 The eutectic mixture is placed in a container and heated to melt it to obtain LiNO 3 -NaNO 3 -KNO 3 molten liquid, and heated up to 290 ° C, while passing nitrogen to drive out the air in the container, the Sn 0.99 Cu 0.01 The alloy is carefully added to the above molten liquid, and after the metal emulsion is formed under the action of ultrasonic waves, it is rapidly cooled to room temperature to obtain a solid;
[0031] 3) The obtained solid was washed with water to remove nitrate, and dried under vacuum at 40°C for 12 h to obtain micron-sized Sn 0.99 Cu 0.01 powder, its scanning electron image is as figure 1 shown;
