Among pure metals, platinum is the best electrocatalyst for the oxygen reduction reaction
(ORR) in direct methanol fuel cells. Its activity is further improved when supported on a high …

This study demonstrates promising bifunctionality of nitrogen-doped carbon nanostructures
(CN x) for ORR and OER in acidic medium. Although CN x catalysts are not as active as Pt/C …

A green synthesized gold-catalyst (PDA-gC 3 N 4/Au) for highly efficient reduction of
nitroaromatics by NaBH 4 was proposed. Polydopamine (PDA) served as the reductant and …

Oxygen reduction reaction (ORR) is one of the fundamental reactions that occur on the
cathode of fuel cells. The sluggish kinetics of ORR and the high cost of the conventionally …

Lanthanum based electrocatalytically active LaMO 3 (M= Cr, Mn, Fe, Co, Ni) perovskites
were synthesized using a single step solution combustion technique. The structural and …

Polymer electrolyte membrane fuel cells (PEMFCs) are a fast growing next-generation
energy conversion technology, which hold promising interest for transportation and other …

Four carbonaceous materials (acetylene black, multi-walled carbon nanotubes, and two
carbon materials synthesized by hard-template method) were used as a support to …

A simple and green method for the deposition of gold nanoparticles (Au NPs) on the surface
of polydopamine (PDA)-encapsulated Fe3O4 nanoparticles is proposed to fabricate a core …

Crystalline cobalt oxide nanoparticles have been densely and strongly anchored onto mildly
oxidized multiwalled carbon nanotubes (Co3O4/mMWCNT) and applied as electrocatalysts …

Graphene based non precious metal catalysts for oxygen reduction reaction (ORR) has
been successfully fabricated through pyrolysis of a mixture of Fe, Co salts, polyaniline, and …
