“…Amorphous alloys have received increased attentions as potentially desirable catalysts, owing to their unique isotropic structures and high concentration of coordinatively unsaturated sites . In particular, the amorphous Ni−B alloy catalyst has been shown to be a superior hydrogenation reaction (HDR), hydrodesulfurization (HDS), and hydrodenitrogenation (HDN) catalyst. Both HDR and HER involve the adsorbed hydrogen atoms as an intermediate on the surface, with both HDR and HER requiring a similar binding energy of hydrogen.…”

A fruitful paradigm in the development of low‐cost and efficient water splitting systems for hydrogen generation is to search the highly active non‐noble catalysts towards hydrogen evolution reaction (HER). Here, the electrocatalytic HER activity of nanostructured amorphous nickel boride (Ni−B) alloy has been investigated. Amorphous Ni−B has exhibited excellent catalytic efficiency and long‐term stability for HER over a broad pH range, which is actually comparable to the performance of Pt. This high catalytic activity is due to the amorphous structure and the moderate electron structure of Ni−B. The Ni−B catalyst is easily obtained via electroless plating technique and we could get a supported Ni−B catalyst on desired substrates. Given the low cost, abundance, corrosion resistance, high efficiency and ease of fabrication, amorphous Ni−B is among the best alternatives to noble metal hydrogen evolution catalysts for water splitting.

“…Transition metal boride materials have attracted considerable attention in recent years. For example, (i) nickel boride (NiB) and cobalt boride (CoB) are being explored as catalysts for the hydro‐desulfurization reaction; (ii) molybdenum borides and iron diboride (FeB 2 ) are studied as electrocatalysts for hydrogen evolution reaction; (iii) iron diboride (FeB 2 ) and amorphous cobalt boride (Co 2 B) are being developed as electrocatalysts for oxygen evolution reaction; and (iv) titanium diboride (TiB 2 ), vanadium diboride (VB 2 ), iron boride (FeB), and CoB are considered as multielectron transfer anode materials for battery applications . However, if compared to carbides, sulfides or phosphides, which are considered for similar applications, metal borides are far from being extensively explored owing mainly to the difficulties encountered during their synthesis.…”

A Simple, General Synthetic Route toward Nanoscale Transition Metal Borides

Most nanomaterials, such as transition metal carbides, phosphides, nitrides, chalcogenides, etc., have been extensively studied for their various properties in recent years. The similarly attractive transition metal borides, on the contrary, have seen little interest from the materials science community, mainly because nanomaterials are notoriously difficult to synthesize. Herein, a simple, general synthetic method toward crystalline transition metal boride nanomaterials is proposed. This new method takes advantage of the redox chemistry of Sn/SnCl , the volatility and recrystallization of SnCl at the synthesis conditions, as well as the immiscibility of tin with boron, to produce crystalline phases of 3d, 4d, and 5d transition metal nanoborides with different morphologies (nanorods, nanosheets, nanoprisms, nanoplates, nanoparticles, etc.). Importantly, this method allows flexibility in the choice of the transition metal, as well as the ability to target several compositions within the same binary phase diagram (e.g., Mo B, α-MoB, MoB , Mo B ). The simplicity and wide applicability of the method should enable the fulfillment of the great potential of this understudied class of materials, which show a variety of excellent chemical, electrochemical, and physical properties at the microscale.

“…It is notable that crystalline Co 2 B and Ni 3 B have relatively low activities and are unstable under HDS conditions. 239 Addition of Mo to Ni-B/boehmite drastically increased the conversion of thiophene from 43% to 74% at a low HDS temperature of 493 K. 240 …”

Synthesis and catalysis of chemically reduced metal–metalloid amorphous alloys

Amorphous alloys structurally deviate from crystalline materials in that they possess unique short-range ordered and long-range disordered atomic arrangement. They are important catalytic materials due to their unique chemical and structural properties including broadly adjustable composition, structural homogeneity, and high concentration of coordinatively unsaturated sites. As chemically reduced metal-metalloid amorphous alloys exhibit excellent catalytic performance in applications such as efficient chemical production, energy conversion, and environmental remediation, there is an intense surge in interest in using them as catalytic materials. This critical review summarizes the progress in the study of the metal-metalloid amorphous alloy catalysts, mainly in recent decades, with special focus on their synthetic strategies and catalytic applications in petrochemical, fine chemical, energy, and environmental relevant reactions. The review is intended to be a valuable resource to researchers interested in these exciting catalytic materials. We concluded the review with some perspectives on the challenges and opportunities about the future developments of metal-metalloid amorphous alloy catalysts.
