A research team led by Professor Zeng Jie from the University of Science and Technology of China (USTC), in collaboration with Researcher Li Xu from the University of Electronic Science and Technology of China, has achieved a significant breakthrough in the field of propane dehydrogenation reaction catalysts. The team has successfully synthesized a silica-supported platinum-indium alloy cluster catalyst and observed that, under the influence of high-concentration propylene, the initially disordered platinum-indium alloy clusters within the catalyst undergo a transformation into ordered platinum-indium intermetallics. This remarkable structural evolution results in a propane dehydrogenation reaction activity that surpasses that of most platinum-based catalysts. The findings of this groundbreaking research have been published in Nature Communications under the title "Reaction-induced Dynamic Evolution of PtIn/SiO₂ Catalyst for Propane Dehydrogenation".
