Sophie’s paper on spontaneous iridium deposition onto nickel for OER

Another paper from Sophie Mellsop, this time in Electrocatalysis. Sophie investigated whether iridium can be spontaneously deposited onto nickel substrates from H2IrCl6 solution to improve oxygen evolution performance in 30% KOH. The approach works well — 45 minutes at 60°C was sufficient to significantly boost OER activity, with H2IrCl6 giving the most active and stable coating. A simple, scalable route to improved alkaline water electrolysis anodes.
