Platinum-Tin Anode for Direct Sugarcane Juice Fuel Cell, a Viable Alternative for Bioenergy Systems: Clean Energy without Production of Vinasse

Abstract

In this study, a bioenergy system utilizing sugarcane juice as fuel was developed using PtSn/C as an anode in various atomic compositions. Results showed that the Pt90Sn10/C composition exhibited a high maximum power density 8.7 mW cm− 2 and open circuit potential of 0.75 V. This research suggests that PtSn/C is a promising material for power devices due to its electronic and bifunctional properties. Analysis of XRD results showed that the lattice parameters expanded, indicating the insertion of Sn into Pt. TEM images and histograms also revealed an increase in average particle size and the presence of tin oxide on the material surface, indicating the effect of tin enrichment in the composition. Overall, this study presents a viable alternative for bioenergy systems that eliminate the production of vinasse.
