Enhanced electrocatalytic activity and durability of Pt nanoparticles decorated on GO-PVP hybride material for methanol oxidation reaction
The alternative energy request is force to find effective electro catalysts used in fuel cell implementations and to enhance the efficiency of existing materials. In this study, graphene oxide (GO) and polyvinylpyrrolidone (PVP) supported shape-controlled platinum nanoparticles (Pt NPs) were newly synthesized with one-pot approach and used as anode materials in the direct methanol fuel cells (DMFCs). The examination for the performance of Pt @GO-PVP NPs was carried out in methanol oxidation reactions (MOR). Pt @GO-PVP catalysts exhibit high stability and activity against the MOR. The methanol oxidation reactions current can reach to 43 mA and can maintain 82.9% of the initial value even after 1000 cycles. The GO-PVP support material provides higher surface area and absorbs more methanol molecules for more efficient oxidation. (C) 2017 Elsevier B.V. All rights reserved.
