Title: Discovery of Accelerated Three-way Catalyst Sintering in Mixed Gas Environments.
Authors: Smith, Jacob; Chi, Miaofang
Abstract: This article, published in the journal Microscopy & Microanalysis, discusses the discovery of accelerated three-way catalyst sintering in mixed gas environments. The study focuses on the sintering of Pt/Al2O3 catalysts at high temperatures in the presence of water vapor and oxygen. Through in situ gas phase scanning transmission electron microscopy, the researchers found that water vapor and oxygen act together to accelerate the rate of sintering by destabilizing and disassociating Pt nanoparticles on the Al2O3 surface. The findings highlight the importance of studying the complex gas interactions in catalyst systems to design more durable and effective catalysts.
