Abstract

Characterization of High-Surface-Area Electrocatalysts Using a Rotating Disk Electrode Configuration.-The method allows the characterization of the electrocatalytic properties of highly dispersed electrocatalysts by attaching the catalyst powder on a glassy carbon electrode via a thin Nafion film. The electrode kinetics for fuel cell relevant reactions under continuous flow conditions can be measured directly without mathematical modeling. -(SCHMIDT, T. J.; GASTEIGER, H. A.; STAEB, G.

Preparation of high loading Pt nanoparticles on ordered mesoporous carbon with a controlled Pt size and its effects on oxygen reduction and methanol oxidation reactions

“…A glassy carbon disk (geometric surface area: 0.126 cm 2 ) was used as a substrate for the Pt/OMC catalyst and the catalyst ink was prepared using a similar method with that of Schmidt et al [61]. Catalyst suspension of 2 mg cm −3 was produced by ultrasonically dispersing the catalyst in water.…”

CO oxidation on non-alloyed Pt and Ru electrocatalysts prepared by the polygonal barrel-sputtering method

“…H 2 SO 4 (96%, Kanto Chemical) with Millipore water. A working electrode was prepared as follows [31,32]. A prepared sample was dispersed uniformly in a solution of 2-propanol and Millipore water with ultrasonic agitation.…”

Effect of reduction conditions on electrocatalytic activity of a ternary PtNiCr/C catalyst for methanol electro-oxidation

“…A glassy carbon electrode (3 mm dia., BAS Co., Ltd., MF-2012) was used as the working electrode. Catalyst layers were deposited by using a thin film method [22]. The catalyst was dispersed in a mixture of DI water and Nafion ionomer solution.…”
