Formation and Functioning of Bimetallic Nanocatalysts: The Power of X‐ray Probes

Abstract: Bimetallic nanocatalysts are key enablers of current chemical technologies, including car exhaust converters and fuel cells, and play a crucial role in industry to promote a wide range of chemical reactions. However, owing to significant characterization challenges, insights in the dynamic phenomena that shape and change the working state of the catalyst await further refinement. Herein, we discuss the atomic‐scale processes leading to mono‐ and bimetallic nanoparticle formation and highlight the dynamics and … Show more

“…Кроме того, Марин и др. обнаружили, что катализаторы Pt-Ga демонстрируют обратимую петлю сплава/сегрегации при воздействии окислительно-восстановительного цикла, чередующегося между 5% H 2 /He и 20% O 2 /N 2 при 600 °C [29,30]. Это обеспечивает стабильность катализатора в процессе реакции/регенерации.…”
