Abstract: This mini review charts the transformation of zeolite from classical heterogeneous catalysts into versatile, grafting-free Pickering interfacial catalysts (PICs). We first introduced the basic stabilization energy theory, which provides us with important guidelines for material design. Generally, zeolites with anisotropic morphology, i.e., layer or fibrous, tend to give higher stabilization energy, thus show more potential of intrinsic amphiphilicity. Particular attention is paid to morphology engineering: ultrathin MWW nanosheets and high-aspect-ratio TON nanofibres with the tuned acidity and zeta potential bestow their ability to stabilize the emulsion. Subsequent deposition of Pd or Pt nanoparticles converts the emulsifier into a Pickering interfacial catalyst that simultaneously stabilizes droplets and catalyzes reactions, such as hydrogenations and Suzuki-Miyaura coupling. Overall, the convergence of crystalline porosity, tunable surface chemistry and catalytic functionality positions zeolite-based PICs as a sustainable cornerstone for next-generation chemical manufacturing.
