Catalytic activities of various Pt catalysts in AB hydrolysis. a Plots of time vs normalized volume of hydrogen gas generated from the AB hydrolysis reaction over the single-atom Pt1/graphene and dimeric Pt2/graphene catalysts. Pt NPs samples of 2cPt/graphene, Pt/graphene-WI, Pt/carbon, Pt/SiO2, and commercial PtO2 powder were also evaluated as a comparison. b The specific rates over these samples based on the mole of Pt
