Tóm tắt

Each step in the catalyst synthesis process plays an important role in tuning the catalyst structures. For zeolite-supported nickel catalysts, we found the conventional calcination-reduction method typically leads to the formation of large nickel particles, but a pre-aging in hydrogen or nitrogen at a low temperature prior to final reduction can result in ultra-small nickel nanoparticles in a metallic state. This pre-aging treatment facilitates the interaction between Ni
