Ammonia-storage active mixture and preparation thereof

The invention relates to an ammonia-storage mixture and preparation thereof. The invention is characterized in that the preparation method comprises the following steps: doping proper amounts of molecular sieve, carbon fiber, deionized water and industrial alcohol in industrial anhydrous magnesium chloride powder; mechanically stirring to obtain a semidry evenly-mixed wet material; and filling into a tank body to prepare an integral porous solid block. The solid block contains abundant ammonia gas transmission pores, has a plurality of macropores in a macroscopic view, has quick ammonia charging property and favorable ammonia storage property, can quickly release ammonia gas, can be used repeatedly without breaking, has efficient adsorption and desorption characteristics, is suitable for adsorbing and storing ammonia gas, is applicable to SCR (selective catalytic reduction) and FCEV (fuel cell electric vehicle) systems, and satisfies the application demands for automobile industry in future.
