Bimetallic RuCo and RuCu catalysts supported on γ-Al2O3. A comparative study of their activity in hydrolysis of ammonia-borane

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

“…Almost all the catalysts reported in the past for hydrolysis of AB are in the form of powder including those supported on certain substrates [7,11,15,[22][23][24][25][26][27][28][29][30]40]. The major problem with this form is that catalysts cannot be easily recovered.…”

“…However, recently, Ru-based catalysts are highly investigated for hydrolysis of AB namely: ruthenium (0) nanoparticles (NPs) supported on hydroxyapatite [22], bimetallic-based RuCo and RuCu alloy supported on -Al 2 O 3 [23], graphene supported Ru NPs [24], water soluble laurate-stabilized ruthenium (0) nanoclusters catalyst [7], Ru/γ-Al 2 O 3 nanopowder [25,26], Ru(acac) 3 [27], Ni@Ru [28], NiRu alloy [29], and PSSA-co-MA stabilized ruthenium (0) nanocluster catalyst [30] etc. Nevertheless, all the catalysts used are in powder form which has the problem related to separation and aggregation during the course of the reaction.…”

“…The absorptive properties of carbon can be tuned by simply decorating the surface of carbon with oxygen-containing groups with acidic, neutral, or basic nature [39]. Ru supported over black carbon [11], multi-walled CNT [40], and graphene [23], displayed outstanding catalytic activity for hydrolysis of AB with very high stability. In all the cases, the enhanced activity is attributed to the role played by carbon in providing high surface area and in dispersing the Ru NPs on the surface to make available good number of active sites.…”

Cobalt-Nickel-Boron Supported over Polypyrrole-Derived Activated Carbon for Hydrolysis of Ammonia Borane

“…Compared to conventional support materials (e.g., SBA-15 [14], carbon black [18], Al 2 O 3 [19], SiO 2 [20], and TiO 2 [21]), porous carbon materials are widely used in industrial applications due to their high surface area, good thermal and mechanical stabilities, chemical inertness, and high physisorption capacity [22][23][24]. Porous carbon materials have attracted attention in materials science and catalysis, and they have emerged as potential supports for growing and anchoring metal nanoparticles.…”

Catalytic performance of bimetallic Ni-Pt nanoparticles supported on activated carbon, gamma-alumina, zirconia, and ceria for hydrogen production in sulfur-iodine thermochemical cycle

“…Bimetallic catalysts have been studied for various catalytic reactions such as catalytic reforming, oxidation-reduction organic reactions, hydrogen generation, and fuel-cell electrocatalysis [33][34][35][36][37][38][39][40][41]. Various methods are available for the production of supported bimetallic catalysts such as co-precipitation [42], sol-gel [43], hydrothermal [44], impregnation-calcination [21], and electroless deposition [45].…”
