Abstract
Techniques for preparing an electrocatalyst include growing and immobilizing an earth-abundant metal on an MXene two-dimensional (2D) substrate using a solvothermal, hydrothermal, or electrodeposition process. The earth-abundant metal may include NiFeOOH. The earth-abundant metal may include Mn, Fe, Co, Ni, Cu, Ti, V, Cr, and a combination thereof. The earth-abundant metal may be nanoparticles. The nanoparticles may include multiple metals. The electrocatalyst may be provided for an oxygen evolution reaction. The electrocatalyst may produce a current density of 500-1000 mA/cm2 for at least 20 hours without degradation thereof.
