摘要	Atomically dispersed catalysts (ADCs) have emerged as a rising star of new materials, exhibiting remarkable catalytic efficiency, selectivity and recyclability. However, little is known about the atomic-scale mechanisms leading to the generic synthesis of fully exposed metals, the feasibility of tailoring metal's coordination environments and the thermal robustness. Here we demonstrate the strong metal support interactions (SMSI) as one of the key factors to universally construct a series of atomically dispersed single metals and synergetic bimetals for high-performance catalysts. The SMSI is realized through the anchoring effects of hybrid sp(2)- and sp(3)-carbons on the surface of nanodiamond@graphene (ND@G) support. Such SMSI assures the effective tuning of metal's coordination numbers by means of either controlling mass loading or introducing complementary species. Furthermore, the impressive thermal stability of ND@G-supported Pt-Sn catalyst as well as the failure route are revealed by atomic resolution in-situ observations. This work not only paves the way towards a library of highly tunable and stable ADCs, but also sheds light on the fundamental regulating principles for their industrial applications.
