Abstract: Six-membered high-entropy foam for hydrogen production by water splitting and preparation method are provided. The foam consists of Ni, Fe, Cu, Co, Mo, and Pt, comprising 10 at %-25 at % of Ni, 10 at %-25 at % of Fe, 10 at %-25 at % of Cu, 10 at %-25 at % of Co, 10 at %-25 at % of Mo, and 10 at %-25 at % of Pt. Catalyst loading of the foam can reach a range of 0.8 mg/cm2-3.2 mg/cm2, which is much higher than the effective catalyst loading of most nano-catalysts. When used as catalyst for hydrogen production by water splitting, the hydrogen evolution overpotential of the surface of the six-membered high-entropy foam is within a range of 36 mV-60 mV, and the foam operates stably at industrial-level current density (500 mA/cm2). The preparation method does not require harsh environment such as high temperature or high vacuum, making the method simple and easy to implement, with low-cost raw materials.
