Abstract EN
The development of base metal catalysts for industrially important reactions continues to be an important goal of catalysis research.
Herein, the effects of pyrolysis temperature on the tex tural, structural, surface, magnetics properties and catalytic properties of silica-supported nickel nanoparticles (NiNPs) were thoroughly investigated.
Mono-dispersed NiNPs encapsulated in gra phitic shells were first successfully obtained and were characterized using a variety of methods such as BET surface area measurement, CO-pulse chemisorption, X-ray diffraction (XRD), X-ray pho toelectron spectroscopy (XPS), high resolution transmission electron microscopy (HR-TEM), and superconducting quantum interference device (SQUID) measurement.
The findings showed that all catalysts' properties were considerably altered with change in pyrolysis temperature.
Hydrogenation of diphenylacetylene was then selected as the model reaction for the evaluation of the catalytic per formance of the graphitic-shelled NiNPs.
After testing, pyrolysis of a nickel at 800 °C (catalyst A) displayed tremendous activity and selectivity to produce > 94% of stilbene with selectivities of 99% for the Z-isomer.
