Abstract

The catalytic activity of NiV2Ox/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 VOx. 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.

负载al2o3的Ni纳米颗粒与VOx†共催化丙烷脱氢
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。
