Ti- Mn based Bimetallic Alloy Electrocatalyst for Improve Hydrogen Evolution Reaction

Developing electrocatalysts that are highly efficient and durable is essential for creating high-performance water-splitting devices, which are crucial for clean energy conversion. Unfortunately, existing electrocatalysts are inefficient and necessitate high overvoltage to facilitate the water-splitting reactions effectively. In this study, we are introducing a titanium-manganese alloy as a promising catalyst for the hydrogen evolution reaction (HER). We evaluated the electrocatalytic activity of the TiMn ₂ alloy for the production of hydrogen in acidic electrolytes. Our results demonstrate that the TiMn ₂ electrocatalyst exhibits a low overpotential of 139 mV for HER in 0.5 M H ₂ SO ₄ and a low Tafel slope of 68 mV/dec at a current density of 10 mA/cm ² and a scan rate of 10 mV/s.In addition to this remarkable activity, the catalyst demonstrates excellent stability as a HER electrode over 24 hours of continuous operation, with minimal activity loss (13.2%).
