On the viability of chitosan-derived mesoporous carbons as supports for PtCu electrocatalysts in PEMFC

Autor: Julia Garcia-Cardona, Ignasi Sirés, Marco Mazzucato, Riccardo Brandiele, Enric Brillas, Francisco Alcaide, Christian Durante, Pere L. Cabot

Chitosan is an abundant and non-toxic natural polysaccharide rich in nitrogen, which is used here to obtain N-doped mesoporous carbons (NMCs) as supports for Pt-saving PtCu alloy elecrocatalysts, which can be of interest for low-temperature fuels cel

Sulfur Doping versus Hierarchical Pore Structure: The Dominating Effect on the Fe-N-C Site Density, Activity, and Selectivity in Oxygen Reduction Reaction Electrocatalysis

Autor: Giorgia Daniel, Tomasz Kosmala, Riccardo Brandiele, Paolo Pastore, Gaetano Granozzi, Christian Durante, Marco Mazzucato, Denis Badocco, Laura De Lazzari

Publikováno v: ACS Applied Materials & Interfaces

Nitrogen doping has been always regarded as one of the major factors responsible for the increased catalytic activity of Fe–N–C catalysts in the oxygen reduction reaction, and recently, sulfur has emerged as a co-doping element capable of increas

How determinant is the iron precursor ligand in Fe-N-C single-site formation and activity for oxygen reduction reaction?

Autor: Christian Durante, Marco Mazzucato

Publikováno v: Electrochimica Acta. 394:139105

Metal-Nitrogen-Carbon (M-N-C) materials have emerged as one of the best non-PGM alternatives to Pt/C catalysts for the electrochemical reduction of O2 in fuel cells. In this work, we explore how decisive is the iron precursor ligand in the Fe-Nx site
