在没有明显迁移到载体（Al 2 O 3）的孔中的情况下，预先形成的和尺寸选择性合成的金属簇（例如Pd或Ni）和由铵盐稳定的金属簇（例如Pt/Sn）可以被特定地放置在外表面上并固定（参见右侧的示意图;黑色：金属簇，灰色：载体颗粒）。初步实验表明，这种皮质催化剂在氢化反应中显示出增加的活性。
Without appreciable migration into the pores of the support (Al 2 O 3), preformed and size‐selectively synthesized metal clusters (eg Pd or Ni) and bimetal clusters (eg Pt/Sn) stabilized by ammonium salts can be placed specifically on the outer surface and immobilized (see schematic representation on the right; black: metal cluster, gray: support particles). Initial experiments indicate that such cortex catalysts show increased activities in hydrogenation reactions.
