The development of highly active, low cost and stable electrocatalysts for direct alcohol fuel cells remains a critical challenge. While Pd₂Sn has been reported as an excellent catalyst for the ethanol oxidation reaction (EOR), here we present DFT analysis results showing the (100) and (001) facets of orthorhombic PdSn to be more favourable for the EOR than (010).

29 p, 950.3 KB Graphene-based Janus micromotors for the dynamic removal of pollutants / Orozco, Jahir (Institut Català de Nanociència i Nanotecnologia) ; Mercante, Luiza A. (Institut Català de Nanociència i Nanotecnologia) ; Pol, Roberto (Institut Català de Nanociència i Nanotecnologia) ; Merkoçi, Arben (Institut Català de Nanociència i Nanotecnologia)
Persistent organic pollutants (POPs) are ubiquitous in the environment as a result of modern industrial processes. We present an effective POPs decontamination strategy based on their dynamic adsorption at the surface of reduced graphene oxide (rGO)-coated silica (SiO)-Pt Janus magnetic micromotors for their appropriate final disposition.

The development of reversible oxygen electrodes, able to drive both the oxygen evolution reaction (OER) and the oxygen reduction reaction (ORR), is still a great challenge. We describe a very efficient and stable bifunctional electrocatalytic system for reversible oxygen electrodes obtained by direct CVD growth of nitrogen-doped carbon nanotubes (NCNTs) on the surface of cobalt boride (CoB) nanoparticles.
