Ni nanoparticles encapsulated within H-type ZSM-5 crystals for upgrading palmitic acid to diesel-like fuels

Abstract Meso-Ni@HZSM-5 bi-functional catalysts were successfully post-encapsulated with about 3–7 nm Ni nanoparticles within HZSM-5 crystals, which exhibited significantly efficient conversion activity (67.4 g[palmitic acid] g[Ni]−1 h−1) of palmitic acid and 100% selectivity of hydrocarbons with the outstanding stability during recycling application, compared to the impregnated Ni/HZSM-5 catalyst (14.0 g[palmitic acid] g[Ni]−1 h−1).
