Demetalation, caused by the electrochemical dissolution of metal atoms, poses a significant challenge to the practical application of single-atom catalytic sites (SACS) in proton exchange membrane-based energy technologies. One promising approach to inhibit SACS demetalation is the use of metallic p...
