The Study of Pt-TiO_2 Composite Electrodes for Photo-Assisted Methanol Fuel Cell

摘要

Metal-titanium oxide composite material is one of the emerging research fields in photochemistry. In this study, platinum nanoparticles (NPs) and Pt thin film were coated on TiO_2 NPs by adopting a simple photo deposition approach. The capabilities for photo enhanced methanol oxidation on electrodes with different types Pt coated TiO_2 were investigated. In methanol oxidation test, the oxidation current found on the Pt NPs modified TiO_2 electrode was magnificently boosted by about 50%, comparing to that of Pt thin film coated ones.
