In recent years, single-atom catalysts (SACs) with high metal loading have emerged in different heterogeneous catalysis fields and shown extraordinary catalytic properties. When there are enough coordination atoms (or functional groups) on the supports, it is possible to achieve a limit monolayer atom surface of supports ultrahigh density (5–15 nm−2) extremely close site distance (0.2–0.5 nm), by using appropriate synthesis methods procedures. These high-density usually no or less bonds, which mostly isolated support form 3D foam-like atomic constructions. Herein, new notion foam (AFCs) propsed redefine these ultrahigh-density SACs accommodated specific supports. This paradigm construction for has potential significance both theoretical research industrial applications. The latest major advancements controllable AFCs various (e.g., polymer, carbon, metallic compound) via (bottom-up top-down approaches) summarized. latent principles typical application cases emphasized wide range thermocatalysis, photocatalysis, electrocatalysis, etc.). challenges prospects this newly materials practical pointed out as well.
