Nanocatalysts for Hydrogen Generation from Ammonia Borane and Hydrazine Borane

Abstract

Ammonia borane (denoted as AB, NH3BH3) and hydrazine borane (denoted as HB, N2H4BH3), having hydrogen content as high as 19.6 wt% and 15.4 wt%, respectively, have been considered as promising hydrogen storage materials. Particularly, the AB and HB hydrolytic dehydrogenation system can ideally release 7.8 wt% and 12.2 wt% hydrogen of the starting materials, respectively, showing their high potential for chemical hydrogen storage. A variety of nanocatalysts have been prepared for catalytic dehydrogenation from aqueous or methanolic solution of AB and HB. In this review, we survey the research progresses in nanocatalysts for hydrogen generation from the hydrolysis or methanolysis of NH3BH3and N2H4BH3.

Hydrazine Borane and Hydrazinidoboranes as Chemical Hydrogen Storage Materials

“…With such catalytic materials, different results were obtained in terms of hydrogen generation rate and catalytic lifetime. For the reason that will be evoked in the next sub-section and because focusing on the catalytic activity is off topic here, the reader is referred to the following review articles for more information about the catalysts, their performance and the kinetic parameters [32,[36][37][38].…”

Surface‐modified carbon black derived from used car tires as alternative, reusable, and regenerable catalysts for H 2 release studies from sodium borohydride methanolysis

“…H 2 is the frontrunner amongst all the sustainable energy carrier as can be attainable from many sources, water splitting through electrolysis that can utilize solar and wind powers, from biomass and natural gas and so on. H 2 is a carbon‐free, environmentally ecological friendly, and possess high‐energy density compared with petroleum‐based fuels . H 2 can also be stored in hydride forms with many metals such as sodium borohydride (NaBH 4 ), lithium borohydride (LiBH 4 ), potassium borohydride (KBH 4 ), aluminum borohydride, and even as ammonium borane (NH 3 BH 3 ) .…”

On-demand Hydrogen Production from Organosilanes at Ambient Temperature Using Heterogeneous Gold Catalysts

“…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.…”
