The stability of a PtRu/C electrocatalyst at anode potentials in a direct methanol fuel cell

open access: yesJournal of Power Sources, 2006
Potential-scan tests were conducted to evaluate the stability of a PtRu/C electrocatalyst at anode potentials in a direct methanol fuel cell (DMFC). The results show that, under normal operating conditions, the anode potential in a DMFC is benign for the

Single‐Atom Electrocatalysts

Angewandte Chemie International Edition, 2017
AbstractRecent years have witnessed a dramatic increase in the production of sustainable and renewable energy. However, the electrochemical performances of the various systems are limited, and there is an intensive search for highly efficient electrocatalysts by more rational control over the size, shape, composition, and structure.

NMR of Electrocatalysts

The Journal of Physical Chemistry B, 2002
It is now possible to investigate in detail metal/liquid interfaces by solid-state NMR under external potentiostatic control, in the presence of an electrolyte, by using the electrochemical NMR (EC NMR) technique. This permits the determination of the electronic properties of electrodes and of adsorbates as well as the study of the surface diffusion of

Characterization of Electrocatalyst

2020
In the process of developing a catalyst, understanding their structure and properties is considered essential as it is obligatory to improve their performance or to resolve a failure issue. Hence, the purpose of this invited chapter is to give a brief summary of various characterization tools specifically, X-ray Diffraction (XRD), Brunauer, Emmett, and
