Abstract
A simple galvanostatic method is reported on the preparation of bimetallic Pt-Sn and trimetallic Pt-Sn-Ni catalysts onto graphite sheet electrode and studied their catalytic activity towards isopropanol (2-Propanol/2-PrOH) and ethanol (EtOH) electro-oxidation. These catalysts have been characterized by SEM, EDX, CV and amperometry. The results indicate that the Pt- Sn-Ni catalyst performs better than the binary Pt-Sn catalyst for both the alcohols. The results are explained in terms of bifunctional effect, electronic effect and strong adsorption of intermediate products.
