A Review of Graphene Supported Electrocatalysts for Direct Methanol Fuel Cells

Abstract

As a fascinating two-dimensional nanomaterial, graphene is attractive for electrocatalytical application in direct methanol fuel cells due to its unique structure and outstanding physical properties. Graphene and its derivatives have been widely used as a support material to improve electrocatalytical activity of catalyst particles for methanol and ethanol oxidations. In this review, discussion is focused on the graphene supported monometallic and bimetallic nanocrystals hybrid materials for electrocatalysts. Additionally, the nitrogen-doped graphene utilized for promising support material in electrocatalysts was also mentioned. We believe that the article will be useful to researchers interested in graphene-based catalyst and related materials for direct methanol fuel cells and provide the present status of the subject.

“…Pt-based materials are regarded as the uppermost MOR catalysts for direct methanol fuel cells. 43 Additionally, the binding energies of CO as well as OH species on catalysts are the descriptors to evaluate MOR performance. 44 As shown in Figure 3C,D, the binding free energies of CO (ΔG ads(CO) ) on the PtNi and PtNi-Se v surface are −2.04 and −1.97 eV, respectively.…”

Preparation and Electrocatalytic Characteristics of PdW/C Catalyst for Ethanol Oxidation

“…Development of novel catalysts with high electrocatalytic activity for ethanol oxidation has received much attention because the electroactivity of anodic materials is one of the main factors influencing the practical application of direct ethanol fuel cells (DEFCs) [1,2]. Palladium (Pd), as one of OPEN ACCESS platinum(Pt) group elements, could hold high electro-oxidation catalytic activity and has larger abundance and lower price compared to Pt [3,4].…”
