Synthesis of nano-sized Pt/C via zeolite-templating method and its application to the cathode catalyst in PEMFC

Experimental study of characteristics of bimetallic Pt–Fe nano-particle fuel cell electrocatalyst

“…So far, the most promising fuel cell electrocatalyst is the high-loading carbon supported Pt [3,4]. In recently studies, zeolite has been used as Pt supported substrate in cathode proton exchange membrane (PEM) fuel cell [5,6] and also as electrode for methanol oxidation, in which the Pt particle size has played an important role in improving the fuel cell electrochemical oxidation and reduction activity [7]. While it was reported that the Pt catalytic activity could be enhanced with increase in Pt surface area [8], there was little understanding on the contribution of protons or auxiliary metal ions (e.g.…”

UV-crosslinkable anthracene-based ionomer derived gas “Expressway” for anion exchange membrane fuel cells

“…4a, where QPPO and PPOAN fills a large number of pores and limits N 2 access to the adsorption sites when mixed with Pt/C while showing the worse adsorption characteristics on the N 2 adsorption isotherms. 58 In the low-pressure adsorption region ( p / p 0 < 0.01), there was virtually no hysteresis, and the pressure increased immediately, which indicated the corresponding micropore volume was very small due to ionomer incorporation. 56 In contrast, CPPOAN@Pt/C possessed better adsorption characteristics, with significant adsorption in the low-pressure adsorption region, representing micropores.…”

An unexpected triammine(oxalato)platinum(II) complex obtained from the aqueous solution of tetraammineplatinum(II) oxalate

“…, have been widely studied and used as the precursors for the manufacture of industrial catalysts [1][2][3][4][5][6][7]. However, [Pt(NH 3 …”
