摘要: Abstract Supportless Ni-Pd-0.1CNT foamy nanocatalyst with specific surface area of 611.3 m2/g was produced by electroless deposition nickel, palladium and multiwall carbon nanotube (MWCNT) on interim polyurethane substrate. Application temperature programmed reduction (TPR) oxidation (TPO) data into Kissinger (Redhead) kinetic model showed lessening their activation energies due to Pd CNT addition. Presence Ni/SiC caused 8% higher steam reforming methane; while presence resulted in 22% methane conversion. The catalytic behavior the samples described morphological compositional studies which were carried out transmission electron microscope (TEM), field emission scanning (FESEM) equipped energy dispersive spectroscopy (EDS) atomic absorption spectrometer (AAS) pondered Brunauer–Emmett–Teller (BET), TPR, TPO X-ray diffraction (XRD).
