Efficient Hydrogen Generation from Ammonia Borane on Skeletal Cu Catalysts Prepared from Cu-Ti Amorphous Alloys

Abstract

The catalytic performances of skeletal Cu prepared from Cu Ti amorphous alloy heated at various temperatures were tested for the hydrogen generation from ammonia borane. The catalytic activity per surface area decreased with increasing heating temperatures of Cu Ti amorphous alloy. The thermal treatment of Cu Ti amorphous alloy leads to the high surface area of skeletal Cu. A skeletal Cu catalyst prepared from heated Cu Ti amorphous alloy at 300°C which is a moderate temperature somewhat lower than crystallization temperature, exhibited a higher catalytic activity in this reaction.

“…However, these reactions are difficult to control and can result in an explosion. Chemical hydrides, such as ammonia-borane456 and formic acid78, are leading candidates for new hydrogen storage materials because of their hydrogen content and highly efficient catalysts for producing H 2 from these molecules have been reported91011121314151617181920212223. However, for effective functioning, these catalysts often require heat energy91014 and anaerobic conditions1112141522.…”
