Abstract
Single-Atom Catalysts Carbon-supported single-atom catalysts are subjected to surface oxidation and hydroxylation upon long-term exposure to ambient environment, causing severe performance degradation. The hydrogen passivation strategy developed by Jianglan Shui and co-workers in article number 2103600 can protect the catalytic active sites and ultimately improve the storage stability of single-atom catalysts.
