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 fields, such as catalysis, sensors, optics, solar energy, cancer therapy/diagnosis, and bioimaging. 10–16 At the same time, the amount and type of metal atoms in the NPs influence 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).…”
