The present application belongs to the field of inorganic metal hydrogen storage material preparation and processing technology, and particularly relates to an activation method of deactivated Ti-Mn-based AB2 type hydrogen storage alloy. The present application co-dopes a small amount of LaNi5 alloy and metal V in the long-stored and deactivated Ti-Mn-based AB2 type hydrogen storage alloy, grinds and mixes, manually press-molds, smelts, and then crushes to obtain a new type of high-performance Ti-Mn-based AB2 type composite hydrogen storage alloy, which can efficiently activate the existing deactivated Ti-Mn-based AB2 type hydrogen storage alloy, restore good initial kinetics and hydrogen storage capacity, and activate a large amount of long-stored and deactivated Ti-Mn-based AB2 type alloy without significantly affecting the cost of the alloy, thereby promoting the wide use of Ti-Mn-based AB2 type alloy in solid-state hydrogen storage devices.

The invention discloses a coal gangue microwave-chemical synergistic activation method and activated coal gangue, the coal gangue microwave-chemical synergistic activation method comprises the following steps: (1) crushing coal gangue to obtain a crushed product; (2) mixing the crushed product with a composite activator, and performing microwave treatment to obtain an activated product; the composite activating agent comprises waste alkali liquor, fly ash aluminum extraction residues and water glass; and (3) drying, cooling and grinding the activated product to obtain the activated coal gangue. The microwave-chemical synergistic activation method for the coal gangue is high in activation efficiency, efficient destruction of crystal lattices of coal gangue minerals is achieved through the synergistic effect of microwaves and the composite activating agent, the activation time is shortened, the silicon-aluminum dissolution rate is increased, the silicon dissolution rate reaches 80% or above, the aluminum dissolution rate reaches 70% or above, the problem that single chemical activation is low in efficiency is solved, and the method is suitable for industrial production. And the obtained activated coal gangue product has high activity.
