Circumventing the wettability issue of heterogeneous metal catalysts for solvent-free organic transformations (opens in new tab)

Substituting homogeneous metal catalysts with recyclable heterogeneous metal catalysts has long been a goal in catalysis. However, most approaches yield heterogeneous metal catalysts that often exhibit relatively low stability and diminished catalytic activity under practical reaction conditions. Herein, we present an inorganic Rh catalyst obtained by confining subnanometer Rh clusters within a self-pillared zeolite structure. This catalyst design not only stabilizes the subnanometer Rh activ...
