TLDR
An overview of the recent progress in methanol and ethanol electrocatalysis on platinum-based materials, with special attention focused on the research effort to reduce platinum content is given in this article.Abstract:
Methanol and ethanol, having high energy density, likely production from renewable sources, and ease of storage and distribution, are ideal combustibles for fuel cells wherein their chemical energy can be converted directly into electrical energy. However, the slow, incomplete oxidation of methanol and ethanol on platinum-based anodes as well as the high price and limited reserves of platinum has hampered the practical application of direct alcohol fuel cells. Extensive research efforts have been dedicated to developing high-activity electrocatalysts. This chapter presents an overview of the recent progress in methanol and ethanol electrocatalysis on platinum-based materials, with special attention focused on the research effort to reduce platinum content.read more

Spectroelectrochemical Study of Carbon Monoxide and Ethanol Oxidation on Pt/C, PtSn(3:1)/C and PtSn(1:1)/C Catalysts
TL;DR: The elevated catalytic activity toward the EOR at PtSn-based electrodes is mainly associated with the improved CO tolerance and the incomplete oxidation of ethanol to form acetic acid and acetaldehyde species, causing the formation of a higher amount of both C2 products with the rise of Sn loading.
