Expanded graphite as an electrode material for an alcohol fuel cell

The influence of the crystal structure of TiO2 support material on Pd catalysts for formic acid electrooxidation

“…An active catalyst should be dispersed on a convenient support to stabilize the catalytic nanoparticles, to obtain optimum catalyst utilization, and to reduce the amount of precious metal used, thus reducing catalyst costs [1]. In direct methanol/formic acid fuel cells, highly conductive carbon materials, such as XC-72, expanded graphite [2], graphite nanofibers [3], ordered porous carbon [4][5][6][7][8][9] and carbon nanotubes [10][11], provide a high dispersion of metal nanoparticles and facilitate electron transfer, resulting in better catalytic activity. To further improve the catalytic activity and stability of the catalyst, the carbon support materials were modified with semiconducting oxides, such as WO 3 [12] and TiO 2 [13][14][15][16][17].…”

Investigation of Electrocatalytic Properties of Pt/Mo - Expanded Graphite Composite Derived from Graphite Intercalation Compound

“…Among supports, carbons such as activated carbon, carbon black, graphite and graphitized material are used [1]. Recently, the use of expanded graphite as a catalyst support was also reported [2,3].…”

Modification of expanded graphite resulting in enhancement of electrochemical activity in the process of phenol oxidation

“…A developed porous structure, high adsorption capacity, low density, and high thermal resistivity of EG make possible its application in many technical fields, for example as heavy oil sorbent [1,2] and composite filler [3]. On much less scale EG has found application as a material for the generation and storage of energy in fuel cells [4], supercapacitors [5], and for the hydrogen sorption/desorption [6]. In order to extend the range of the EG potential application, various types of its modification were attempted.…”
