IPC-1P, a layered zeolite precursor with a relatively high density of surface silanols can be swollen using docosyltrimethylammonium hydroxide and functionalized with ultra-small Rh nanoparticles. The resulting mesoporous zeolitic material Rh@IPC_C22 has a high layer disordering without microporosity. In situ STEM imaging during heating and DFT simulations show strong metal-silanol interactions stabilizing Rh nanoparticles against thermal sintering.
