Title: Growth of Crystalline Polyaminoborane through Catalytic Dehydrogenation of Ammonia Borane on FeB Nanoalloy

Abstract

Tremendous effort has been devoted to the study of complex and chemical hydrides for hydrogen storage in the past decade [1, 2]. Ammonia Borane (NH 3BH 3, AB) with a hydrogen content of 19.6 wt % has received significant attention [3-5]. Methods to improve the kinetics of the step-wise dehydrogenation of AB are diverse including the uses of mesoporous frameworks [6], catalysts [7-16], and additives [17]. It was reported that when dissolving in organic solvents AB released hydrogen readily in the presence of transition metal catalysts through the formation of M∙∙∙HBH 2NH 3 complex (where M is Ir, Ru, or Ni etc.) [8-10]; Lewis or Brønsted acids, on the other hand, react with AB in solution to form the initiating species (BH 2NH 3) + [11], which may have the similar function as the [BH 2(NH 3) 2] +BH 4 - (DADB) in the dehydrogenation of solid AB [17, 18]. However, comparatively little study has been reported on the catalytic dehydrogenation of AB in solid form. Other important but less investigated aspects in the solid-state reaction are the characterizations of functional catalytic species and products from the step-wise dehydrogenation.
