Co-electrodeposited PtPd anodic catalyst for the direct formic acid fuel cells

The origins of formic acid electrooxidation on selected surfaces of Pt, Pd, and their alloys with Sn

“…These oxophilic metals have a lower onset potential for water activation than Pt, facilitating CO* oxidation with higher activity. Various bimetallic alloys such as PtPb, 14 PtBi, 15 PtRu, 7 PtIr, 16 and PtPd 17 have been experimentally investigated and found to enhance FAO activity compared to monometallic Pt, and Pd catalysts. Mavrikakis and co-workers 7 studied P 3 M bimetallic catalyst (P = Pt or Pd, M = Au, Ag, Cu, Pd, Pt, Ir, Rh, Ru, or Re, where P ≠ M) for FAO via DFT calculation and found higher activity for PtRu, PtIr, PdRu, and PdIr than Pt and Pd catalyst.…”

Efficient Electro-Oxidation of 2-Propanol at Platinum- and Gold-Modified Palladium Nanocatalysts

“…To address these concerns, cost-efective, clean, and renewable energy sources that could be used as viable substitutes for fossil fuels are urgently needed [5][6][7][8][9]. Energy storage and conversion devices have received worldwide interest as a key step toward using renewable energy resources as primary energy sources, and it has become necessary to thoroughly examine the various promising energy conversion and storage solutions, such as fuel cells (FCs) [10][11][12][13][14][15][16][17][18][19], and embark on their implementation [3,12]. In this regard, the direct alcohol fuel cells, such as the direct 2-propanol FCs (D2PFCs), appeared as excellent candidates [20][21][22][23][24][25][26].…”
