One-step hydrothermal synthesis of a Ni₃S₂–FeMoO₄ nanowire–nanosheet heterostructure array for synergistically boosted oxygen evolution reaction

Abstract

We propose a one-step hydrothermal strategy to fabricate hierarchical Ni3S2–FeMoO4 nanowire–nanosheet heterostructures on NiFe-foam as structurally-integrated electrodes for synergistically boosted OER at high current density.

Ruthenium-doped Ni(OH)2 to enhance the activity of methanol oxidation reaction and promote the efficiency of hydrogen production

“…At present, precious metals (Pt and Pd) and their alloys are still the most effective catalysts for the small molecule oxidation-assisted hydrogen production system. 12,13 However, Ru is less expensive than Pt, which is one of the alternatives to Pt-based catalyst. 14 Thus, new methods may be investigated to increase the use of ruthenium metal and enhance its catalytic oxidizing capacity, which is essential to lower precious metal waste, develop appropriate non-Pt-based catalysts, and enhance their usage.…”
