چکیده انگلیسی
Poly(p-phenylene) (PPP) films with good electrochemical activity and good thermal stability were synthesized by a low-potential electrochemical polymerization of biphenyl in pure boron trifluoride diethyl etherate. As-formed PPP film was firstly used as a catalyst support. Pd-Au nanoparticles were successfully electro-deposited on PPP films (namely, Pd-Au/PPP) and used for the electrooxidation of isopropanol in alkaline media. The Pd-Au/PPP composite catalyst shows a high electrochemical active surface area in the hydrogen adsorption potential region. The results for isopropanol oxidation indicate that Pd-Au/PPP have higher catalytic activity and stronger poisoning-resistance than the Pd-Au deposited on the bare electrode. Furthermore, the role of PPP in the composite catalyst and supplemental effect are discussed. The present study evidences that Pd-Au/PPP is a promising choice as a composite catalyst for isopropanol electrooxidation in alkaline medium.
