Abstract

Hydrolysis of Zr(BH₄)₄·8NH₃ in deionized water can generate high purity hydrogen at room temperature. However, the sluggish hydrolysis kinetics of Zr(BH₄)₄·8NH₃ hinders its practical use. To improve its hydrogen generation properties, the effects of magnetic stirring, changing hydrolysis solution and tuning the ammonia coordination number on the hydrolysis properties of Zr(BH₄)₄·8NH₃ were investigated. Results show that both changing hydrolysis solution and tuning the ammonia coordination number can enhance the hydrolysis kinetics. The hydrolysis kinetics properties of Zr(BH₄)₄·8NH₃ were significantly improved in MgCl₂ and CoCl₂ solutions. The Zr(BH₄)₄·xNH₃ (x ≤ 8) samples were synthesized by a ball-milling method with different ammonization time (10, 60 and 180 min). Both the hydrolysis kinetics and hydrogen yield of Zr(BH₄)₄·xNH₃ (x ≤ 8) were enhanced as the ammonia coordination number (x) decreased. Thus, tuning ammonia coordination number is an effective way to control the hydrolysis properties of Zr(BH₄)₄·xNH₃ (x ≤ 8).
