Bimetallic nanomaterials for direct alcohol fuel cells

Modification of multi-walled carbon nanotubes with platinum–osmium to develop stable catalysts for direct methanol fuel cells

“…Nanoparticles (NPs) have important applications in various elds, such as catalysis, sensors, optics, solar energy, cancer therapy/diagnosis, and bioimaging. [10][11][12][13][14][15][16] At the same time, the amount and type of metal atoms in the NPs inuence the catalytic activity, 10,17,18 while the removal and adsorption efficiency of undesirable elements during chemical reactions are affected by the composition of the metal. Metal NPs and their complexes generally outperform conventional catalysts in terms of catalytic performance due to advantages, such as high surface-to-volume ratios and compact size (in the case of NPs).…”

Synthesis of a functionalized carbon supported platinum–iridium nanoparticle catalyst by the rapid chemical reduction method for the anodic reaction of direct methanol fuel cells

“…6 Therefore, different nanostructures have been used in DMFCs. 4,7,8 Likewise, it is known that Pt-based metals, bimetals and their alloys such as Pt, Pt–Ir, and Pt–Fe–Ru are also good catalysts in the investigation of the electrocatalytic oxidation mechanism (MOR) and kinetics of methanol. 9–11 Pt-based nanomaterials are considered effective anode electrocatalysts for DMFCs 12–14 and Pt is preferred in many studies because it shows superior electrocatalytic activity and conductivity.…”

Facile Synthesis of Fiber‐Reinforced Catalyst for High Performance Ethanol and 2‐Propanol Oxidation

“…Direct alcohol fuel cells (DAFCs), which are classified as fuel cells, are systems that generate electrical energy as a result of the electrochemical reaction of alcohol fuels. [5,6] Compared to conventional power generation systems, DAFCs have higher chemical-to-electrical energy conversion efficiency, higher energy density, and lower greenhouse gas emissions. [1] DAFCs are recognized as reliable, clean, and efficient sustainable energy conversion technologies.…”
