Hydrothermal synthesis of titanium-supported PtIrRu/Ti electrode and its electrocatalytic activity

Sol–gel synthesis of Pt-Ru-Os-Ir based anode electro-catalysts for direct methanol fuel cells

“…Improved anode catalysts can be obtained by synthesizing high surface area Pt-Ru based alloy catalysts combined with engineered proper alloy design by modifying the chemical composition of the alloy, and doping or alloying with other elements onto the catalyst structure [3,7,[10][11][12][13][14][15][16][17][18]. Several researchers have reported significantly improved performance in ternary and quaternary alloys of Pt-Ru-Os, Pt-Ru-Ir, Pt-Ru-Sn, Pt-Ru-Ni, Pt-Ru-P, Pr-Ru-Ni-Zr, PtRu-Os-Ir etc.…”

“…Several researchers have reported significantly improved performance in ternary and quaternary alloys of Pt-Ru-Os, Pt-Ru-Ir, Pt-Ru-Sn, Pt-Ru-Ni, Pt-Ru-P, Pr-Ru-Ni-Zr, PtRu-Os-Ir etc. when compared to pure Pt-Ru alloys [14][15][16][17][18][19][20]. Out of the different multi-component systems, it has been reported that Pt-Ru-Os and Pt-Ru-Os-Ir exhibit superior catalytic activity in comparison to other systems [14][15][16]22,23].…”

“…In addition to alloy development, considerable efforts have also been devoted to synthesize high surface area binary or ternary Pt-Ru based alloy catalysts to achieve higher methanol oxidation activity [7,[10][11][12][13][20][21][22][23][24][25]. Hence, several approaches have been reported for synthesizing high surface area Pt-Ru based binary or ternary alloy nano-particles anode catalysts primarily using halide precursors of the respective components, which inevitably require several follow-up washing treatments to remove the undesired halide secondary residues [7,[10][11][12][13][14][15][16][17][18][19][20][21]. As a result, these processes are cumbersome and cost-inefficient leading to significant loss of the starting noble metal precursors.…”

Hydrothermal Synthesis of Titanium‐Supported Nickel Nanoflakes for Electrochemical Oxidation of Glucose

“…Because of its excellent properties, like corrosion-resistant, high mechanical strength, reasonable cost, wide electrochemical potential windows and good stability, titanium has been applied as a substrate used to fabricate novel and stable electrocatalysts including the well known DSA (RuO 2 -TiO 2 /Ti) electrode [27] and PbO 2 /Ti etc [28,29]. In addition, novel titanium-supported electrodes including nanoporous Pt/Ti [30,31], bimetallic PtIr/Ti [32], PtRu/Ti [33], and ternary PtIrRu/Ti [34] have been prepared and they present significantly high electroactivity towards oxygen reduction reaction, methanol oxidation and formic acid oxidation. In this work, we report on the preparation of novel titanium-supported nickel nanoflakes (nanoNi/Ti) by using the hydrothermal process.…”

Synthesis of highly dispersed platinum nanoparticles on multiwalled carbon nanotubes and their electrocatalytic activity toward hydrogen peroxide

“…On the other hand, transition metal nanoparticles like gold [7], platinum [8], palladium [9], copper [10], nickel [11] and their binary [12][13][14][15][16][17][18] or ternary metals [14,[19][20][21] are widely used to enhance the performances of electrodes because of their high catalytic activity. Particularly, Pt nanoparticles (PtNPs) are demonstrated to lower the H 2 O 2 oxidation/reduction overvoltage efficiently [22][23][24][25], which is very important for biosensors to avoid interference from other co-oxidable substances like ascorbic acid and acetaminophen.…”
