The invention discloses a method for preparing nano-rod-shaped magnesium fluoride, which uses anodized aluminum oxide as a template, fills a magnesium fluoride precursor or magnesium fluoride into the pores of the template, and after drying, roasting and curing, and roasting and curing The product is washed with a template removal agent to remove the template, then washed with deionized water to remove the template removal agent, and finally dried to obtain nanorod-shaped magnesium fluoride, the nanorod-shaped magnesium fluoride having a diameter of 20-500nm and a length of 20-500nm. at 0.5‑500µm. The magnesium fluoride prepared by the invention has a special rod shape, and has strong anti-sintering ability when used in reaction systems such as fluorine-chlorine exchange reaction, dehydrochlorination reaction, dehydrogenation reaction and isomerization reaction. The catalyst life is improved and its industrial application is expanded. |
