High efficient electrooxidation of formic acid at a novel Pt-indole composite catalyst prepared by electrochemical self-assembly
Self-assembly of Pt and indole into a novel composite catalyst on a glassy carbon electrode (GC) has been developed by a one-step electrodeposition in the presence of 3.0 mM H-2 PtCl6 and 0.1 mM indole. Compared to Pt/GC and Pt/C, the novel Pt-indole composite catalyst exhibits higher catalytic activity and stronger poisoning tolerance for electrooxidation for formic acid. The adsorption strength of CO on the prepared Pt-indole composite catalyst is greatly weakened as demonstrated by CO stripping voltammograms. Because of its advantageous catalytic activity and poisoning tolerance, the novel Pt-indole composite catalyst is anticipated to find interesting applications in many important fields such as energy and catalysis.
