“…Current methods of preparing nanosized particles of TMPs typically employ arrested precipitation or solvothermal routes, both of which require relatively high temperatures. For the late transition metals, pioneering studies by Brock and Schaak on the synthesis of nanosized TMPs have been focused on the use of trioctylphosphine (TOP) and trioctylphosphine oxide (TOPO) at temperatures generally in the range 200–300 °C. − In addition, Brock has also demonstrated that desilylation could be used to produce FeP nanoparticles at 240–300 °C. These high-temperature routes to TMPs in most cases provide the most thermodynamically stable, well-known crystalline phase of the material.…”

Low-Temperature Synthesis of Amorphous FeP₂ and Its Use as Anodes for Li Ion Batteries

The reaction of Fe(N(SiMe(3))(2))(3) with PH(3) in THF at 100 °C gives amorphous FeP(2) in high yield. As an anode material in a Li ion battery, this material shows remarkable performance toward electrochemical lithiation/delithation, with gravimetric discharge and charge capacities of 1258 and 766 mA h g(-1), respectively, translating to 61% reversibility on the first cycle and a discharge capacity of 906 mA h g(-1) after 10 cycles. This translates to 66% retention of the theoretical full conversion capacity of FeP(2) (1365 mA h g(-1)).

“…177,178 The metal halide (chlorides mainly) starting precursors used in the reaction process are generally more sensitive to moisture than their oxide counterparts. Also, many of them have a very low boiling point, for example NbCl 5 (248 °C), TiCl 4 (136.4 °C) and ZrCl 4 (331 °C), [179][180][181] so when they are used, the synthesis reactions often have to be carried out in a closed vessel such as a quartz ampoule or an autoclave. Despite these drawbacks, the MSM-ABRS process does have several merits.…”

Transition meal and rare earth borides have been subjected to extensive investigations because of their unique structures, superior properties and diverse applications. Conventional methods for their syntheses suffer from various drawbacks. So several alternative approaches have been explored. Among them, the so-called ‘molten salt synthesis (MSS)’ technique has proved promising. Over the past 10–15 years, it has been used to prepare a range of transition metal and rare earth borides. In this paper, the main results from these studies are reviewed. Initially, the relevant background on metal borides and their conventional synthesis methods are introduced, followed by the main principles/mechanisms of MSS. The following three sections provide an overview of the main work on MSS of binary and ternary borides, boride solid solutions, and boride-based composite powders. Then, two newly modified MSS approaches are presented. Finally, the main issues covered in this paper are summarised, and future prospects considered.

“…A general rout towards metal boride nanocrytals had been developed by ionothermal process at a relatively mild temperature (500-900 °C) [15]. ZrB 2 can also be obtained by a co-reduction method at low temperature [16,17]. Very recently, a solid-state reaction between zirconium dioxide and sodium borohydride was reported to produce pure nanosized ZrB 2 at the temperature of 1100 °C [18].…”

Iodine-assisted solid-state synthesis and characterization of nanocrystalline zirconium diboride nanosheets A solid-state route was developed to prepare zirconium diboride nanosheets with the dimension of about 500 nm and thickness of about 20 nm from zirconium dioxide, iodine and sodium borohydride at 700 °C in an autoclave reactor. The obtained ZrB 2 product was investigated by X-ray diffraction, scanning electron microscope and transmission electron microscopy. The obtained product was also studied by thermogravimetric analysis. It had good thermal stability and oxidation resistance below 400 °C in air. Furthermore, the possible formation mechanism of ZrB 2 was also discussed.
