摘要

在500℃条件下，nivox /Al2O3对丙烷脱氢（PDH）的催化活性比单金属催化剂高2-5倍，这主要归因于Ni纳米粒子（NPs）和VOx的协同作用。这种协同作用不仅促进丙烯的解吸，还促进H2的生成和解吸，显著提高了催化性能。

Co-catalysis of propane dehydrogenation by Al2O3-supported Ni nanoparticles and VOx†

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.
