Single-atom catalysts(SACs)have received great research interest because of their maximum atom-utilization efficiency and unique catalytic properties[1-5].However,most of the reported SACs only focus on single-site active components,with rare reports studying catalyst promoters in their single-site forms[6-8].Because promoters are essential components in many indus-trial catalysts,the exploration of the single-site promoters should be of great significance in catalysis,both in funda-mental and application research.Similar to SACs,these single-site promoters have structural simplicity and homogeneity,and the synergistic effect on the catalytic reaction should be unique yet clarified.
