“…The results of the ICP and thermal analysis indicate that the resultant is not oxidized. In fact, the fresh metal alloy particles can be oxidized very easily by the oxygen in the air [ 21 ]. In this case, the particles can be cladded by PVP to insulate oxygen from air.…”

“…Room temperature solid-solid chemical reaction is a novel technique for preparation of nanosized materials. Recently, we have found that some amorphous alloys nanoparticles and the copper, bismuth, or antimony nanocrystalline particles can be prepared very easily by room temperature solid-solid reaction [ 18 – 21 ]. The reaction can be quickly accomplished at room temperature, which is a challenge to those traditional methods.…”

The Fe-Ni-Pb-B alloy nanoparticles was prepared by a solid-solid chemical reaction of ferric trichloride, nickel chloride, lead acetate, and potassium borohydride powders at room temperature. The research results of the ICP and thermal analysis indicate that the resultants are composed of iron, nickel, lead, boron, and PVP, and the component of the alloy is connected with the mole ratio of potassium borohydride and the metal salts. The TEM images show that the resultants are ultrafine and spherical particles, and the particle size is about a diameter of 25 nm. The largest saturation magnetization value of the 21.18 emu g−1 is obtained in the Fe-Ni-Pb-B alloy. The mechanism of the preparation reaction for the Fe-Ni-Pb-B multicomponent alloys is discussed.

“…Besides the chemical reduction and electroless plating, the electroplating [98-100] and solid-solid reaction [101] were developed for the synthesis of amorphous alloy. Moreover, the assembly or control of the size and morphology of amorphous alloy has been explored by adjusting the preparation environment, such as in the presence of macromolecule [56], surfactant [88,102,103], microemulsion, and magnetic field [39][40][41][42][43].…”

This paper reviews the advances in the chemical synthesis and application of metal-metalloid amorphous alloy nanoparticles consisting of transition metal (M) and metalloid elements (B, P). After a brief introduction on the history of amorphous alloy catalysts, the paper focuses on the properties and characterization of amorphous alloy catalysts, and recent developments in the solution-phase synthesis of amorphous alloy nanoparticles. This paper further outlines the applications of amorphous alloys, with special emphasis on the problems and strategies for the application of amorphous alloy nanoparticles in catalytic reactions. History of amorphous alloy catalystAmorphous alloys have been extensively investigated internationally over the last 50 years largely spurred by their unique electronic, magnetic and surface properties and their increasing utility in a broad range of applications [1,2]. The amorphous alloy nanoparticles have gained increasing attention as novel catalytic materials since 1980, with the unique isotropic structure and high concentration of coordinatively unsaturated sites leading to catalytic activity and selectivity superior to their crystalline counterparts [3]. Especially, amorphous alloys chemically reduced by borohydride (BH 4 − ) and hypophosphite (H 2 PO 2 − ) have nanosized morphology and consequently higher surface area and activity than those prepared by the quenching method [4][5][6][7][8]. It has been regarded that the amorphous alloy catalyst can be a potential alternative to Raney nickel or noble metal catalyst in catalytic hydrogenation. Raney nickel has shown many serious disadvantages, such as short lifetimes due to poor sulfur resistance and environmental pollution caused by alkaline leaching during preparation. In contrast, the amorphous alloy nanoparticulate catalysts are inexpensive, environmentally benign, and effective catalytic materials.For the chemical synthesis of metal-metalloid amorphous alloy catalysts, Brown et al. and Paul et al. found that the NiB particles reduced by sodium borohydride in water or ethanol solution showed excellent catalytic activity and selectivity in many hydrogenation reactions [9][10][11][12][13][14][15]. After that, and Chen et al. [21][22][23][24] studied the mechanism of borohydride reduction and the relation between properties and preparation conditions. On the other hand, Deng and coworkers have been interested in studying the properties of amorphous alloy particles and the application of metal boron (MB) and metal phosphorus (MP) amorphous alloys for catalytic hydrogenation [25-37]. Dragieva et al. focused on developing amorphous alloys as electrode or catalytic oxidation materials [38-43], while Chen and coworkers prepared MPB alloy nanoparticle catalysts for various selective hydrogenation reactions [44-50]. Amorphous alloy nanoparticulate catalysts have been widely studied by different research groups in China [51-60]. Among them, our group has attempted to develop NiB and NiP industrial amorphous alloy catalysts in various catalyt...
