Nanotechnology is defined as the branch of science dealing with extremely small-sized
particles with a size in the range of 1–100 nm, which are termed nanoparticles. Due to the …

Over the past few decades, direct methanol fuel cells (DMFCs) have been intensively
developed as clean and high-efficiency energy conversion devices. However, their …

Advances in science and nanotechnology have facilitated the development of new methods
for the preparation of pure selenium as selenium nanomaterials. They offer remarkable …

Articles devoted to non-platinum anode catalysts for DMFC and PEMFC application,
operated in acidic media were reviewed. Several classes of possible platinum substitutes …

In the last two decades X-ray absorption spectroscopy (XAS) has increasingly been applied
to the study of fuel cell catalysts and, in particular, Pt containing catalysts for use in low …

Oxygen reduction catalysts have been prepared on the basis of heat-treated, carbon
supported iron phenanthroline complexes. The activity of the catalyst towards oxygen …

This work is part of a continued research aimed at the understanding of the promoting role of
Se in the enhancement of the electrocatalytic activity of Ru in the oxygen reduction reaction …

A carbon-supported Ru85Se15 chalcogenide catalyst was synthesized via a microwave-
assisted polyol process using RuCl3 and Na2SeO3 as the Ru and Se precursors. The …

Stable polymer coated platinum–ruthenium nanoparticles were prepared. The effects of
several preparation parameters have been studied in view of optimizing the particles' …

For efficient operation, mixed-reactant fuel cells utilise highly selective anode and cathode
electrocatalysts. While platinum and its alloys are the most widely used ORR electrocatalysts …
