Active and stable electrocatalysts for oxygen evolution reaction (OER) are crucial in the widespread application of water electrolyzers. Cobalt phosphide nanoparticles (Co-P) with different degrees crystallinity synthesized via solvothermal phosphidization Co metal-organic frameworks P4 using solvents. The Co-P can be converted to active OER 1 M KOH, most reaching 10 mA cm-2 current densities a...

Proton Exchange Membrane (PEM) water electrolysis (WE) produces H2 with a high degree of purity, requiring only and energy. If the energy is provided from renewable sources, it releases “Green H2”, CO2-free H2. PEMWE uses expensive rare noble metal catalysts, which hinder their use at large industrial scale. In this work, electrocatalytic properties Transition Metal Phosphides (TMP) catalysts s...
