“…Ni-Fe bimetallic phosphides (NiFeP) nanorods were synthesized at a low-temperature phosphorization process using a hydrothermal technique (Du et al, 2018). In the method, a Ni-Fe bimetallic-organic frameworks (MIL-88-Fe 2 Ni MOF) precursor was used to engineer NiFeP nanorod structures.…”

“…An enormous effort has been made for the development of low-cost metal catalysts with phosphides doping (Cui et al, 2015). Ni-Fe phosphide nanorods exhibited electrocatalytic activity with a lesser overpotential of 243 mV (vs. RHE) at 20 mA.cm −2 , smaller Tafel slope of 69.0 mVdec −1 , and a higher exchange current density of 79.4 µA cm −2 in the HER within basic medium (Du et al, 2018). The synergetic effect developed between NiP 2 and FeP enhanced the electrocatalytic activity of NiFeP bimetallic phosphides nanorods.…”

Bimetallic nanoparticles (BNPs) have attracted greater attention compared to its monometallic counterpart because of their chemical/physical properties. The BNPs have a wide range of applications in the fields of health, energy, water, and environment. These properties could be tuned with a number of parameters such as compositions of the bimetallic systems, their preparation method, and morphology. Monodisperse and anisotropic BNPs have gained considerable interest and numerous efforts have been made for the controlled synthesis of bimetallic nanostructures (BNS) of different sizes and shapes. This review offers a brief summary of the various synthetic routes adopted for the synthesis of Palladium(Pd), Platinum(Pt), Nickel(Ni), Gold(Au), Silver(Ag), Iron(Fe), Cobalt(Co), Rhodium(Rh), and Copper(Cu) based transition metal bimetallic anisotropic nanostructures, growth mechanisms e.g., seed mediated co-reduction, hydrothermal, galvanic replacement reactions, and antigalvanic reaction, and their application in the field of catalysis. The effect of surfactant, reducing agent, metal precursors ratio, pH, and reaction temperature for the synthesis of anisotropic nanostructures has been explained with examples. This review further discusses how slight modifications in one of the parameters could alter the growth mechanism, resulting in different anisotropic nanostructures which highly influence the catalytic activity. The progress or modification implied in the synthesis techniques within recent years is focused on in this article. Furthermore, this article discussed the improved activity, stability, and catalytic performance of BNS compared to the monometallic performance. The synthetic strategies reported here established a deeper understanding of the mechanisms and development of sophisticated and controlled BNS for widespread application.

Nickel phosphide (Ni 2 P/C) hollow microspheres were synthesized via a facile two-step route based on metal-organic framework (MOF) precursors. Unlike direct phosphating the MOF by calcination that would damage the MOF structure and that would form multiple phases, solvothermal method was able to convert the Ni-based MOF to one-pure-phase nickel phosphide with the MOF skeleton maintained, as suggested by XRD, XPS, and SEM. When using as the battery-supercapacitor hybrids electrode material, the optimized Ni 2 P/C exhibited the specific capacity 670.4 C/g (1676 F/g) at 1 A/g in a threeelectrode system, and a maximum energy density 42.74 Wh/kg at 764.23 W/kg in an asymmetric supercapacitor. It also delivered an energy density of 35.39 Wh/kg at 7000 W/kg with the rate capability retention of 92 % after 5000 cycles. The high specific surface area and the increased amount of electrochemically active sites endowed by the unique morphology, together with the low charge transfer resistance all contribute to the excellent electrochemical performance of the Ni 2 P/C material. These also indicate that solvothermal method is feasible in converting MOF to metal phosphide for the application in energy storage and conversion systems.[a] Prof.

Hierarchical Cobalt Sulfide/Molybdenum Sulfide Heterostructure as Bifunctional Electrocatalyst towards Overall Water Splitting

The development of non‐noble metal based electrocatalysts for overall water splitting is a potent strategy towards a carbon‐neutral and clean energy economy. Herein, hierarchical CoSx@MoS2 was synthesized via a one‐pot solvothermal process. Formation of the heterostructure was confirmed by electron microscopy and spectroscopic techniques. CoSx@MoS2 showed competent electrocatalytic activity towards both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline medium. Superior electrocatalytic activity was attributed to the increase in number of active sites, betterment in charge transfer and facilitation of H‐ and O‐ containing active species adsorption‐desorption at the active sites. Overall water splitting efficiency of CoSx@MoS2 was found to be superior in comparison to the state‐of‐the‐art RuO2‐Pt/C couple. Along with efficiency the heterostructure also exhibited long‐term operational durability. Thus, hierarchical CoSx@MoS2 is a potential non‐noble metal based bifunctional electrocatalyst towards overall water splitting.
