Hydrogen generation by the reaction of Al with water promoted by an ultrasonically prepared Al(OH) 3 suspension

A high-activity Al(OH)3 suspension is prepared by the reaction of Al with water using an ultrasonic procedure. The above Al(OH)3 suspension could considerably promote the Al-water reaction and hydrogen-generation under ambient condition. This Al(OH)3 suspension has a good stability in air and its activity increases with decreasing the particle sizes of Al powder to prepare it. The mechanism analyses reveal that the Al(OH)3 particles in...
