Phosphorus-induced activation of Ir metallene for efficient acidic overall water electrolysis

Abstract

In this work, we synthesize P-doped Ir metallene (P-Ir metallene) with rich defects as highly active bifunctional catalyst towards hydrogen evolution reaction and oxygen evolution reaction, requiring overpotentials of 28...

An active Ni(OH)2/MnCO3 catalyst with efficient synergism for alkaline methanol oxidation

“…1 Hydrogen receives much greater interest than ever before as a desirable energy carrier. 2 Alkaline water electrolysis stands out as a particularly auspicious approach for hydrogen production, while its catalytic efficiency is hampered by the slow kinetics of the oxygen evolution reaction (OER), which remarkably surpasses the thermal-equivalent potential for water splitting. 3,4 Replacing the OER with a more favorable methanol oxidation reaction (MOR) can decrease the operating voltage as well as the associated costs in hydrogen production.…”
