Resumo da Palestra:

“Platinum is the most used electrocatalyst in electrochemical energy conversion devices such as fuel cells and electrolysers. In my talk I will highlight our recent work on understanding the surface chemistry of platinum in an aqueous electrolyte, by combining single-crystal electrochemistry, density functional theory calculations, ultra-high-vacuum modeling, in situ spectroscopy and in situ electrochemical scanning tunneling microscopy. I will challenge some existing explanations and interpretations of platinum electrochemistry, and show the surface disordering of platinum that happens at both positive (anodic) and negative (cathodic) conditions.”
