Rapid Hydrogen Generation from Aluminum-Water System Using Synthesized Aluminum Hydroxide Catalyst

Hong-Wen Wang and Ming-Ssu Chin
Abstract—Catalytic effect of Al(OH)3 on the hydrogen generation from Al/water system is evaluated. The Al(OH)3 powders are synthesized from various molar ratios of Al(NO3)3 : NaOH = 1:3 ~ 1:5. It was found that the Al(OH)3 catalyst derived from the ratio Al(NO3)3 : NaOH = 1:3.5~1:4 in an ice bath exhibits the best catalytic effect and exerts the highest hydrogen generation rate. Over 95% yield of hydrogen from a 3 g Al/50 ml water system (with 15 g Al(OH)3 and pH=12) can be generated within 100 s. That is, by using specially synthesized Al(OH)3 catalyst at a Al:Al(OH)3:H2O=3:15:50 weight ratio, very rapid hydrogen generation rate (~667 ml/g·Al·min), without using any alloying elements or extreme corrosive condition, can be realized.

Index Terms—Aluminum hydroxide, aluminum nitrate, hydrogen generation.
