Abstract

The catalytic activity of NiV₂O_x/Al₂O₃ for propane dehydrogenation (PDH) at 500 °C was observed to be 2–5 times higher than those of their monometallic counterparts, primarily attributed to the synergistic effect of Ni nanoparticles (NPs) and VO_x. This synergy was concluded to promote not only the desorption of propylene but also the generation and desorption of H₂, significantly improving the catalytic performance.
