Iron‐Nanoparticle‐Catalyzed Hydrolytic Dehydrogenation of Ammonia Borane for Chemical Hydrogen Storage

Abstract

Attractive hydrogen production? The amorphous Fe nanoparticles prepared following a simple but very efficient method possess high catalytic activity (see picture) for the generation of hydrogen from an aqueous solution of ammonia borane, even in air, and can readily be recycled with no obvious loss of catalytic activity.

Carbon-supported platinum-decorated nickel nanoparticles for enhanced methanol oxidation in acid media

“…For clarity, the diffraction patterns between 35°and 45°have been enlarged in the inset of The diffractograms of Ni/C are indicative of a crystalline structure mainly with amorphous state, which could stem from surface layers (The presence of the first peak is due to the supporting material and the broader second peak indicates the amorphous state of the Ni). Compared with Inset The enlarged XRD patterns of Pt/C, PtNi/C, Ni/C, and Pt-Ni/C catalysts its crystallized counterpart, a metal in an amorphous state holds many more lattice defects and thus could give birth to distinct effects in mediating the electronic structure and/or tuning the atomic arrangement and coordination of the outer shell [17,18]. Based on this concept, Pt decorating of amorphous Ni core could be expected to decrease the usage of Pt and enhance its catalytic activity at the same time.…”

Ruthenium nanoparticles supported over carbon thin film catalyst synthesized by pulsed laser deposition for hydrogen production from ammonia borane

“…Heterogeneous route of catalysis involving metal catalysts has been found to be very efficient in accelerating HGR. Various noble and non-noble metal catalysts like Rh [5], Pd [6], Ru [7], Co [8], Ni [9] and Fe [10] nanoclusters, Ru/C powder catalyst [11], K 2 PtCl 6 [12], NiAg [13], Ni@Ru [14], Ru, Rh and Pt supported over γ-Al 2 O 3 [15], Co/γ-Al 2 O 3 [16], nickel and cobalt borides [17][18][19][20] etc., have been generally used to produce hydrogen by hydrolysis of AB.…”

Exploring Promising Catalysts for Chemical Hydrogen Storage in Ammonia Borane: A Density Functional Theory Study

“…Boddien et al [18,19] have examined efficient dehydrogenation of formic acid using an iron-based catalyst, highlighting DFT-based insights and experimental kinetic studies. Yan et al [20] have developed markedly catalytic amorphous iron nanoparticles for H 2 generation from AB. Baker et al have synthesized iron complexes comprising amido-and phosphine-supporting ligands, and have scrutinized the reactivity thereof [21].…”
