제목 High dispersion of supported metal catalysts on zeolitic mesopore walls
초록 Supported metal catalysts played a central role in many heterogeneous catalysis. Highly dispersed form of metal nanoparticles are generally preferred in terms of catalytic activity. High dispersion of supported metal nanoparticles can be readily achieved at low metal loading. However, supported metals become to be distributed in an inhomogeneous manner with increasing in loading amount. In this contribution, we reported that MFI zeolite nanosponges can support transition metal nanoparticles (e.g., Ni, Cu, Co) on the mesopore walls in a highly dispersed form at a very high content (~20 wt.%). Such a high dispersion might be attributed to three-dimensional interconnections of uniform mesopores and ordered arrangement of Si-OH groups onto the zeolitic mesopore walls. The MFI zeolite nanosponges supported on 20wt% Ni nanoparticles exhibited a high catalytic activity in CO2 methanation reaction, as compared to MCM-48 supporting on 20wt% Ni nanoparticles.
