Influence of complexing agents on the preparation of bimetallic platinum–ruthenium catalysts supported on O-functionalized graphite cloths

Selective synthesis and characterization of metallic cobalt, cobalt/platinum, and platinum microspheres

“…Various methods have been successfully applied to the synthesis of bimetallic nanoparticles and hollow noble metallic materials [15,16,[30][31][32][33][34][35][36][37][38][39]. An alternative route has been reported to prepare hollow noble metal materials with different shapes by a transmetalation reaction in which suitable metal ion nanoparticles react with a sacrificial partner and finally lead to the formation of hollow spheres inheriting the morphology of the sacrificial partner, and urchinlike hollow metallic and bimetallic nanospheres have been synthesized [40][41][42].…”

Preparation, characterization and utilization of (Ni:Cu) bimetallic system loaded on zeolites

“…The use of bimetallic system as a catalyst is recently attracted more interest not only due to the highly synergetic effect of bimetallic systems but also due to the change in the physical properties of the resulted alloy which affects mainly the stability and the durability of the catalysts [15][16][17][18][19][20][21][22][23][24].…”

Methanol, ethanol and ethylene glycol electro-oxidation at Pt and Pt–Ru catalysts electrodeposited over oxidized carbon nanotubes

“…For instance, Tsai et al [11] prepared highly dispersed nano-sized PteRu deposits on CNTs by a potentiostatic pulse technique and reported a high catalytic activity for methanol oxidation. On the other hand, Sieben et al [12] prepared PteRu catalysts supported on oxidized graphite felt from solutions containing different complexants and found that the catalyst prepared using Na 2 H 2 EDTA as a stabilizer had high mass activity for methanol oxidation. Ando et al [13] developed efficient PteRu/C electrocatalysts for methanol oxidation with ultra low content of Pt and Ru using galvanic displacement of Pb by Pt and Ru.…”
