Terbium: Water Splitting catalyst for Powering hydrogen

A wide range of applications require the design of excellent, affordable, and stable electro-catalyst systems for practical applications. One promising method and tactic for creating a sustainable and clean energy source is large-scale electrolytic water splitting. In this work, we use a hydrothermal technique to stepwise surface-redox-etch Tb foam (TF) to create a self-supported electro-catalyst from Tb-CoB LDH-Tb-CoO electro-catalyst. The Tb-CoB LDH-Tb-CoO was produced. Water oxidation produces a current with a density of roughly 100mA.cm-2 at a voltage of just 240 mV. The hydrogen evolution reaction, on the other hand, requires 276 mV in 1 M potassium hydroxide. In a two-electrode alkaline electro-catalyst, the synergistic impact of Tb-CoB LDH-Tb-CoO results in the development of a highly self-supported catalytic system that can split water by crossing a 10 mA.cm-2 current density at just 1.53 V. To ensure durability and potential as a real-world energy conversion system, the developed electrode generates a stable performance for an extended period of time with a high density of current.
