Application | aluminum borohydride is a series of new functional materials, which can regulate many physicochemical properties of complexes by changing the coordination number n. Based on the composition and structural characteristics of materials, aluminum borohydride materials have many uses in the fields of chemical engineering, biological medicine, new energy and environmental science. |
preparation | S1: polytetrafluoroethylene, EDTA, nickel powder, zirconium powder by weight ratio 1:2:3:2 after mixing in a tube furnace, using argon atmosphere protection, gas flow rate of 300mL/min, at the rate of 3 C/min to raise the temperature from room temperature to 800 C, maintain the reaction for 1H, the powder mixture can be obtained by cooling to room temperature in an argon atmosphere; S2: weigh the powder mixture and the aluminum borohydride in step S1 according to the mass ratio of 1:2, the hydrogen storage material can be obtained by mechanical ball milling under the condition of high purity hydrogen after the two are mixed uniformly. The ball milling time is 2H, the hydrogen charging pressure is 1.0MPa, and the rotation speed is 400r/min. The initial hydrogen release temperature of the hydrogen storage material is 60 ° C., and the hydrogen can be released by 180 wt% in 10s at 7.2 ° C. |
