A facile synthesis of monodisperse cobalt–ruthenium alloy nanoparticles as catalysts for the dehydrogenation of morpholine borane and the hydrogenation of various organic compounds

Abstract

Herein we report a novel wet-chemical protocol for the composition-controlled synthesis of monodisperse cobalt-ruthenium (CoRu) alloy NPs and their catalysis in the hydrolytic dehydrogenation of morpholine borane (MB) for chemical...

Designing an industrially viable bimetallic catalyst for the polyol synthesis

“…Two satellite peaks at binding energies of 788.4 eV and 804.8 eV show the contribution from the CoO species. 32 These results imply that while Ru is mainly present in a metallic form, Co is present in a higher oxidation state.…”

Bimetallic Nanoalloy Catalysts for Green Energy Production: Advances in Synthesis Routes and Characterization Techniques

“…[1] For this purpose, scientists have recently attracted much interest in several areas, including electrocatalysis and heterogeneous catalysis. [2] They focused on developing energy conversion and storage solutions that are highly efficient, costeffective, and have minimal environmental impact to meet energy demands. This approach emphasizes low emissions and improved efficiency.…”

Green Approaches to Dehydrogenation of DMAB Catalyzed by Starch Stabilized Ru(0), Cu(0) and Ni(0) Nanoparticles in the Absence of a Solvent

“…For this purpose, many studies are carried out with commonly used solid hydrogen storage materials such as ammonia borane [32,33] and dimethylamine borane, [34,35] as well as new derivatives such as ethylene diamine-bisborane, [36][37][38] methylamine borane [39][40][41] and morpholine borane. [42,43] Among them, dimethylamine-borane (Me 2 NHBH 3 , DMAB), which has many properties such as low melting point, high stability, durability, sustainable environmental and economic advantages, is one of the most preferred amine borane derivatives in hydrogen production. [44][45][46] In addition, DMAB, the only chemical hydride with a melting point close to room temperature (∼ 35 °C), can be used as both solvent and hydrogen source.…”

“…Although the production, storage and use of hydrogen, which is a promising energy carrier, is still an important problem for industrial applications, all the researches to solve this problem are focused on to obtain alternative amine borane derivatives to be used as solid storage materials with thermal stability, ease of hydrogen release and high hydrogen density. For this purpose, many studies are carried out with commonly used solid hydrogen storage materials such as ammonia borane [32,33] and dimethylamine borane, [34,35] as well as new derivatives such as ethylene diamine‐bisborane, [36–38] methylamine borane [39–41] and morpholine borane [42,43] …”
