Colloquium - 03 July 2024 – Prof. Andreu Cabot, Catalonia Institute for Energy Research (IREC)

Title: Bottom-up engineering of energy conversion materials and devices

Time: 2024-07-03 14:00 - 15:30

Venue: Institute for Energy Research, 1517

Organizer: Institute for Energy Research

Abstract:

Colloidal synthesis routes allow extremely precise control over material parameters without particularly high capital or operating costs (ambient pressures, low temperatures) and with high-throughput production and material yields. For such control over material parameters to truly impact real applications, colloidal nanocrystals need to be properly organized or arranged into functional unsupported superstructures, high-resolution patterns, thin films, porous nanomaterials or highly dense nanocomposites, depending on the application. In this talk, I will present our recent work on the colloidal synthesis of high entropy alloy nanoparticles, discuss their electrocatalytic properties and demonstrate their potential as oxygen catalysts at the cathode of metal-air batteries. Additionally, I will talk about the printing of nanostructures using a jet-deflection electrohydrodynamic printer.
