Schematic illustration of the synthesis of Co1/G SACs with tuneable loadings. The first cycle of Co ALD by an alternative exposure of the support to CoCp2 vapor and O3 gas at 150 °C; the second cycle of Co ALD on Co1/G to deposit another batch of Co atoms on the active sites created by O3 treatment at 150 °C in the previous Co ALD cycle; more cycles of Co ALD results in a high loading of Co1 SACs. The balls in gray, white, red, and blue represent carbon, hydrogen, oxygen, and cobalt, respectively
