In heterogeneous catalysis, supports play a crucial role in modulating the geometric and electronic structure of the active metal phase for optimizing the catalytic performance. A γ‐Al2O3 nanosheet that contains 27 % pentacoordinate Al3+ sites can nicely disperse and stabilize raft‐like Pt‐Sn cluste...
