Combinatorial screening of fuel cell cathode catalyst compositions

Effect of sputtering parameters on surface morphology and catalytic efficiency of thin platinum films

“…A very uniform particle distribution was observed resulting in an increased electrochemically active surface and decreased Pt loading relative to a commercial chemically dispersed Pt catalyst. Cooper [19,20]. The influence of the sputtering parameters however, has not been presented in details.…”

Combinatorial search for oxygen reduction reaction electrocatalysts: A review

“…Composition gradient was generated by depositing Pt, Pd, and Au simultaneously in a specially designed chamber where each target was off-centered so that ternary compositions are produced as each metal is deposited with different ratios at each position. The formation of concentration gradient is well Cooper and McGinn [25] fabricated binary and ternary composition arrays including PteRu, PteCoeTi, PteCoeCu and PteCoeCr by employing plasma sputtering technique. The arrays contained 63 different compositions which were generated using 6 different shadow masks during the sputtering process.…”

Combinatorial Search for Quaternary Methanol Tolerant Oxygen Electro‐Reduction Catalyst

“…Since that study, ) was observed in the Pt(50)Ru(10)Fe(20)Se(10)/C catalyst than for the Pt/C catalyst 6.51 lA cm pt various techniques have been employed for library synthesis (solution dispensing [22], physical vapour deposition [23,24] and electrodeposition [25]) and characterisation (optical screening [21,26], multielectrode half-cell [27,28], multielectrode single cell [29] and scanning electrochemical microscopy [30,31]) [32]. Although, various systems such as PtCo [33], PdCo [34], PtCoCr [35], PtTi [36], PtPdAu [37], RuFe [38], PtRuIr and PtRuPd [39] have been investigated for ORR activity via the combinatorial method, there have been no reports of methanol tolerant ORR catalysts investigated via the combinatorial synthesis and high-throughput screening methods.…”
