AI Technical Summary

Technical Problem

Existing precious metal-based catalysts are expensive and rare, resulting in low efficiency of the oxygen evolution reaction (OER) in the process of hydrogen production by water electrolysis, making it difficult to apply them on a large scale.

Method used

A self-supporting oxygen evolution electrode material was adopted. Transition metal oxides (TMOs) were directly grown on porous foam metal and combined with carbon nanotubes. The material was then modified using atmospheric pressure non-equilibrium oxygen plasma jet to form a carbon nanotube composite material coated with Fe and Co metal elements. This reduced the water splitting overpotential and improved the OER activity.

Benefits of technology

It effectively reduces the overpotential of water splitting, accelerates the OER process, improves the efficiency of hydrogen production by water electrolysis, and significantly enhances the stability and catalytic activity of the material.
