Study of Pt catalyst on graphene and its application to fuel cell

Reduced Graphene Oxide and Its Modifications as Catalyst Supports and Catalyst Layer Modifiers for PEMFC

“…This could be attributed to a poor utilization of the catalyst surface. When graphene-like materials are used as catalyst supports, the method of catalyst synthesis and the type of graphene precursor significantly influences the EASA of the resulted catalysts [32,33,34,35]. For instance, the catalyst utilization can change from 28% to 93% depending on the synthesis procedure for graphene-supported catalysts [32].…”

Polymer fuel cell components modified by graphene: Electrodes, electrolytes and bipolar plates

“…In consequence, improved results appeared in terms of fuel cell performance with a power density of 90 mW cm À 2 , which was higher than Pt/Vulcan -72 mW cm À 2 . This results from the enhanced conductivity, electrochemical surface area and excellent electrocatalytic activity [86].…”

“…In the other work [86] Pt nanoparticles on graphene (PtNPs/ GN) were prepared from graphite oxide. Graphene oxide sheets were synthesized by modified Hummers' and Offeman's method.…”

3D Pt/MoO 3 nanocatalysts fabricated for effective electrocatalytic oxidation of alcohol

“…(NH4) 6 the type of Vulcan XC72R was acquired from CABOT Corp. All the reagents with analytical grade were utilized as purchased. Deionized water was used throughout.…”

“…Based on the alcohols or other organic fuels, direct alcohol fuel cells (DAFCs) have attracted much attention in recent years due to the potential applications as the power sources in portable electronics, fuel cell vehicles, and other usages [1][2][3][4][5]. By the direct injection of the certain liquid alcohol fuels, the difficulties of production, purification and storage of hydrogen will not arise in the DAFCs [6][7][8]. Among small organic molecule fuels, methanol can be oxidized more easily and efficiently, while ethanol is the most promising fuel due to the lower toxicity, higher abundance, and wider convenience in industry [9,10].…”
