Abstract Iron single‐atom catalysts (SACs) have garnered increasing attention as highly efficient catalysts for the oxygen reduction reaction (ORR). yet their performance in practical devices remains suboptimal due to the low density of accessible active sites. Anchoring iron single atoms on 2D support is a promising way to increase the accessible active sites but remains difficult at... https://parisnaturalfoodes.shop/product-category/dmae-advanced-firming-cream/
