“…Ozay's group originally studied Cu, Co, and Ni particles with average sizes of 75–150 nm that was formed in polymeric‐(acrylic acid‐ co ‐vinyl‐imidazole) hydrogel network structures, as catalysts for the hydrolysis reaction of EDAB. [ 267 ] Hydrogels are 3D cross‐linked polymeric networks which, by swelling, retains water up to several hundred times their dry weight in aqueous media. Their hydrophilic functional groups and anionic structures are thus relevant for metal ions as absorbent material support.…”

Dihydrogen is one of the sustainable energy vectors envisioned for the future. However, the rapidly reversible and secure storage of large quantities of hydrogen is still a technological and scientific challenge. In this context, this review proposes a recent state-of-the-art on H 2 production capacities from the dehydrogenation reaction of ammonia borane (and selected related amine-boranes) as a safer solid-source of H 2 by hydrolysis (or solvolysis), according to the different developed nanoparticle-based catalysts. The review groups the results according to the transition metals constituting the catalyst according a special view to current cost/availability consideration. This includes the noble metals Rh, Pd, Pt, Ru, Ag, as well as transition metals such as Co, Ni, Cu, and Fe. For each element, the monometallic and polymetallic structures, isolated or supported, are presented and the performances described in terms of TOF and recyclability. The structure-property links are highlighted whenever possible. It appears from all these works that the mastery of the preparation of catalysts remains a crucial point; not only in terms of process but also in terms of mastery of the electronic structures of the elaborated nanomaterials. A particular effort of the scientific community remains to be made in this multidisciplinary field with major societal stakes.

“…At the same time, in the FT-IR spectrum of the SPVI hydrogel, the peaks observed at 1497 cm À 1 (C=C), 1278 cm À 1 (CÀ N), 1162 cm À 1 (SO 2 asymmetric stretching as overlapped with CÀ OÀ C asymmetric stretching vibration of ester group) and 1037 cm À 1 (SO 2 symmetric stretching as overlapped with CÀ OÀ C symmetric stretching vibration of ester group) supported the presence of both monomers in the structure. [3,13] The morphological structure of SPVI was investigated by SEM analysis. SPVI hydrogel that had reached equilibrium swelling ratios in DIW was freeze-dried using a lyophilizator, then the SPVI pieces were coated with gold and then SEM analyzes were performed.…”

This study describes the synthesis of Pd 0 nanoparticles supported in hydrogel networks (SPVI@Pd) and their catalytic activity for the borane-morpholine complex (MB) hydrolysis reaction. In this respect, while our study is one of the limited number of studies reported for the catalytic hydrolysis of MB, it is the first study in which Pd 0 nanoparticles supported in hydrogel networks were used in the catalytic hydrolysis of MB. The synthesized Pd 0 nanoparticles were characterized using structural and morphological characterization techniques and as a result of these analyses, the sizes of Pd 0 nanoparticles were determined average as 7.01 � 1.90 nm. The E a value and the turnover frequency (TOF) value at 303 K for the SPVI@Pd 3.0 catalyzed MB hydrolysis reaction were determined as 49.46 kJ/ mol and 187.74 mol H2 ⋅ mol Pd À 1 ⋅ h À 1 . It was also observed that the SPVI@Pd 3.0 catalyst had good catalytic activity even after eight cycles.

Here, the first ever preparation of some series of nanoceria‐supported Ru‐based nanoparticles with different compositions (RuxM100‐x@NC, M: Co, Ni, Pd) and their use as highly active catalysts to liberate hydrogen gas from hydrolysis of ethane 1,2‐diamine borane (EDAB) is reported. For the preparation of totally fifteen RuxM100‐x@NC nanoparticles with different compositions, the related metal cations are first supported on nanoceria surfaces by wet impregnation method in aqueous solution. Then, Ru3+‐M2+‐exchanged nanoceria samples are synchronously reduced during hydrolysis reaction of EDAB to form corresponding RuxM100x@NC nanoparticles meanwhile the formed nanoparticles catalyze the same reaction. RuxM100x@NC nanoparticles are identified by inductively coupled plasma‐optical emission spectroscopy (ICP‐OES), powder X‐ray diffraction (PXRD), transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), and BET surface area techniques. They provide quiet high catalytic activities in the hydrolysis reaction of EDAB. Among them, Ru20Pd80@NC nanoparticles are by far the best one up to date with a TOF value of 608.49 min−1 at 25 °C.
