摘要
Fundamental knowledge of structure-activity correlations for heterogeneous single-atom catalysts(SACs)is essential in guiding catalytic design.While linear scaling relations are powerful for predicting the performance of traditionalmetal catalysts,they appear to fail with the involvement of SACs.Comparing the catalytic CO oxidation activity of different atomically dispersed metals(3d,4d,and 5d)in conjunction with computational modeling enabled us to establish multiple scaling relations between the activity and simply calculated descriptors.
