Hydroisomerization of linear paraffins to branched isomers is an important petrochemical process, which is commonly conducted by bifunctional catalysts of Pt-supported on zeolites for high catalytic performance.1 In this process, an inexpensive Ni has been tested to replace high-cost Pt component in the bifunctional catalysts for the hydroisomerization. In this work, we synthesized mesoporous MFI and *MRE zeolite by using structure-directing surfactant and mesoporous TON zeolite by a post desilication-dealumination treatment and loaded Ni nanoparticles to these mesoporous zeolites.2 Such Ni-loaded mesoporous MFI, *MRE, and TON samples showed even better catalytic performance than those of 0.5 ~ 1.0 wt% Pt-loaded counterparts. These high catalytic performances on Ni-supported mesoporous zeolites was attributed to the tiny Ni nanoparticles that were stabilized by the confined mesoporous channels and facile diffusion property of mesoporous zeolites. 1Deldari, H.; Appl.
