CoPi-modified mesoporous titania photoelectrodes for water splitting: why less is more
Autor: Priscila Vensaus, Lucas Nahuel Mendioroz, Facundo Carlos Herrera, Mark Patrick Kreuzer, Federico Andres Viva, Galo Juan de Ávila Arturo Soler Illia
Titanium dioxide is a promising candidate for photoelectrochemical water splitting; however, its performance is limited due to the sluggish oxygen evolution reaction (OER). In this work, a hybrid nanomaterial was developed by combining ordered mesopo

Platinum-based cathode catalyst systems for direct methanol fuel cells
Autor: Federico A. Viva
Metallic platinum has been and still is the most active electrocatalyst for several reactions, including the oxygen reduction reaction (ORR). This reaction, in which gaseous oxygen is reduced to water, is the cathode process for polymer electrolyte m
