Cost-effective and readily available catalysts applicable for electrochemical conversion technologies are highly desired. Herein, we report the synthesis of dithiophosphonate complexes of the type [Ni{S2P(OH)(4-CH3OC6H4)}2] (1), [Co{S2P(OC4H9)(4-CH3OC6H4)}3] (2) and [Fe{S2P(OH)(4-CH3OC6H4)}3] (3) and employed them to prepare Ni2P, Co-Ni2P and Fe-Ni2P nanoparticles. Ni2P was formed by a facile hot injection method by decomposing complex1in tri-octylphosphine oxide/tri-n-octylphosphine at 300 °C. The prepared Ni2P was doped with Co and Fe employing complexes2and3, respectively, under similar experimental conditions. Doping Ni2P with Co and Fe demonstrated synergistic improvement of Ni2P performance as an electrocatalyst in supercapcitance, hydrogen evololution and oxygen evolution reactions in alkaline medium. Cobalt doping improved the Ni2P charge storage capacity with a supercapacitance of 864 F g?1at 1 A g?1current density. Fe doped Ni2P recorded the lowest overpotential of 259 mV to achieve a current density of 10 mA cm?2and a Tafel slope of 80 mV dec?1for OER, better than the undoped Ni2P and the benchmark IrO2. Likewise, Fe-doped Ni2P electrode required the lowest overpotential of 68 mV with a Tafel slope of 110 mV dec?1to attain the same current density for HER. All catalysts showed excellent stability in supercapacitance and overall water splitting reactions, indicating their practical use in energy conversion technologies.

A sulfur-rich nickel complex has been synthesized by the reaction between 2,4-bis(4-methoxyphenyl)- 1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson’s reagent) and Ni(NO3)2·6H2O in 2-propanol. The complex has been characterized by elemental analysis, IR,1H NMR,13C NMR, and31P NMR spectroscopies and molar conductivity. Also, the crystal structure of the complex has been investigated by X-ray diffraction, which illustrates a slightly distorted square planar environment around Ni(II) ion in solid. Furthermore, the crystal structure of the complex shows 3D network through intermolecular C-H…Ni, CH O, and C-H S hydrogen bonds and C–H π interaction.
