Electrochemical potential of poly(viniyl acohol) modified bacterial nanocellulose as platinum nanoparticles support

Abstract

The main objective of this work was to prepare new platinum supported catalyst on BNC/PVA composite as nanoparticles carrier, designed for electrocatalytic applications. For that purpose, BNC/Pt suspension was mixed with 1 wt% PVA solution and BNC/PVA/Pt catalyst in the form of film was successfully synthesized. The structure and thermal properties of catalyst were characterized by ATR-FTIR and TG analysis, respectively, while its crystallinity was investigated by XRD analysis. Electrocatalytic potential of BNC/PVA/Pt catalyst was tested in methanol oxidation reaction. Remarkable catalytic activity of new Pt based catalyst was confirmed. The obtained results for catalyst activity was comparable to those obtained for preferentially used carbon based Pt supports pointing that BNC based composited can be considered as great substitution of carbon based materials with the green one.
