We report nitrogen-doped biomass-derived porous carbon materials with great performance for the Oxygen Reduction Reaction (ORR) in alkaline media. The level of nitrogen doping in a simple pyrolysis of corncob (CC) was varied systematically, a 1:1 CC:

The green synthesis of platinum nanoparticles between 3 and 7 nm was achieved using an aqueous extract, and then supported on high surface area carbon obtained from the pyrolysis of the same natural source, which is finally used as an electrocatalyst

Pt–CoTiO3 nanocatalysts were supported on RGO functionalized with the Cr(CO)6 and [(ƞ6-C6H6)Cr(CO)6] organometallic compounds and characterized for the oxygen reduction reaction (ORR). Different stoichiometric ratios of Cr(CO)6 gave mono- and bis-

A green methanol functionalization of Vulcan XC-72 as novel strategy to develop high-performance Pt1Sn1 electrocatalyst was studied. The electrocatalysts were synthesized by the intermittent microwave heating (IMH) polyol method. X-ray diffraction me

Herein, we report a methodology that leads to the formation of Ru metallic sites, followed by the development and anchorage of Pt-Ru alloyed nanoparticles on the surface of Ordered Mesoporous Hollow Carbon Spheres (OMHCS). Along with the Ru sites, it

In this work, low-Pt content nanocatalysts (≈ 5 wt. %) supported on Hollow Carbon Spheres (HCS) were synthesized by two routes: i) colloidal conventional polyol, and ii) surfactant-free Bromide Anion Exchange (BAE). The nanocatalysts were labelled
