Fabrication of robust noble metal nanoparticles (NPs) usually suffers from instability due to the large surface energy of small particles. Herein, highly dispersive Pd nanoparticles (average size: ∼3 nm) with controllable content were directly encapsulated within pure silica zeolite matrix with TON topol. via a dry gel conversion pathway, in which 1-butyl-3-methylimidazolium bromide and (3-mercaptopropyl) trimethoxysilane were utilized as the structure-directing agent and metal stabilizer, resp. High crystallinity and large surface area were reached over this Pd containing zeolites. The champion catalyst Pd-Si-ZSM-22 effectively catalyzed the transformation of furfuryl alc. into tetrahydrofurfuryl alc. via hydrogenation by using H2. High conversion (>99%) and selectivity (>99%) were reached with large turnover numbers and the stable activity was observable during the recycling test. The comparison with the post-impregnated counterpart indicates that the straightforward synthesis is favorable for the construction of stable and robust Pd species within the confined microchannels of TON zeolites.
