Improved hydrogen generation from Al/water reaction using different synthesized Al( OH ) ₃ catalyst crystalline phases

The catalytic influence of different crystalline phases of aluminum hydroxide nanoparticles for the hydrogen generation from the reaction of Al and water is described. In this study, different aluminum hydroxide powder crystalline phases (mixed-phase, bayerite phase, gibbsite phase), (Al(OH)3), were distinctly prepared using precipitation methods in different solvents (methanol, ethanol, and HNO3) at room temperature (25°C). Interestingly, the...
