We report the development of an efficient and earth-abundant catalyst for electrochemical overall water splitting. Trimetallic NiFeMo alloy is synthesized by hydrothermal deposition from inorganic precursors and subsequent low-temperature thermal annealing. A complete cell made of NiFeMo electrodes on nickel foam exhibits a low voltage of 1.45 V at 10 mA/cm2 as a result of low overpotentials ...
In pursuit of sustainable hydrogen production, alkaline water electrolysis offers fossil-free technology for generating hydrogen. Exploring new non-precious metal electrocatalysts plays a crucial role in this endeavor. Herein, we investigate a trimetallic NiFeMo material on a nickel foam support, serving as a bifunctional electrocatalyst for catalyzing both the hydrogen evolution reaction (HER ...
In this work, we successfully synthesized nanocluster structure composites composed of NiFeMo alloys with controllable lattice strain by the electrodeposition method at room temperature. The unique structure of NiFeMo/SSM (stainless steel mesh) facilitates the exposure of abundant active sites and promotes mass transfer and gas exportation.
The NiFeMo trimetallic film supported on nickel foam (NF) synthesized by Qin et al. showed good performance in overall water splitting; 6 unfortunately, its smooth and compact surface hindered the further increment of activity due to the lack of active area.
The carbon compound NiFeMo-P anchored on nickel foam (NiFeMo-P-C) was successfully constructed via hydrothermal and hydrogen reduction methods. The synergistic effect between alloy and metal phosphide, as well as the carbon composition and partially broken hollow morphology, allowing for much higher oxygen evolution reaction (OER)/hydrogen evolution reaction (HER) activity and superior stability.
ABSTRACT: We report the development of an efficient and earth-abundant catalyst for electrochemical overall water splitting.

Herein, we proposed an electrochemical in situ etching method to achieve molybdenum component-controlled dissolution of ultrathin NiFeMo layered double hydroxides (LDHs) nanosheet arrays on nickel-iron foam (NFF) to create in situ reconstructed oxygen evolution reaction (OER) active sites in LDHs.
Compared to the NiFe-LDH without Mo, the NiFeMo-LDH nanosheet arrays exhibited enhanced activities with 17.1 mV/dec less Tafel in OER. The good performance of the electrocatalyst is ascribed to the special nanosheet arrays and the heterostructure of the Ni-Fe-Mo system.
