Highly clean and efficient iron phosphates modified by Ru nanocrystals for water oxidation

curve shows no distinct variations in current over 45 h at a constant overpotential of 334 mV, indicating the outstanding activity and durability of the catalyst. Furthermore, nickel/cobalt-rich phosphates and phosphides were also acquired using similar experimental procedures, manifesting the wide applicability of Ru actuation. Hence, this work offers a convenient and scalable method for designing highly efficient, green, clean, and cost-effective electrocatalysts for water splitting.
