| Abstract: | In CO hydrogenation, small (ca. 1 nm) Pt–Ir bimetallic clusters encapsulated in the supercage of NaY zeolite showed significant non-linear Schulz-Flory distributions, especially high selectivity for C4 hydrocarbons, which is different from those of Pt or Ir clusters entrapped inside the supercage of NaY. |
