Atomic catalytic pairs enable multistep transformations, yet the roles of spatial arrangement and coordination symmetry in homonuclear pairs remain unclear. Here, the authors construct atomically dispersed homonuclear Pt₁–Pt₁ pairs with asymmetric Pt₁C₃–Pt₁O₁C₃ coordination on reduced graphene oxide, enabling efficient transfer hydrogenation of azobenzene.
