Abstract

We have successfully demonstrated large-area and continuous MoS₂ films grown on indium tin oxide (ITO) substrates by RF sputtering followed by a post-annealing process. Thin Cu layers were prepared on MoS₂/ITO films by thermal evaporation to enhance electron-transfer rates as well as the catalytic activity of hydrazine oxidation. High electrocatalytic activity towards hydrazine oxidation was observed in a Cu/MoS₂/ITO hybrid structure. A large residual current was also observed in the Cu/MoS₂/ITO hybrid due to the combination of MoS₂ and Cu film. The electrocatalytic activity was enhanced with the increase of the MoS₂ film thickness. The observed results showed that the Cu/MoS₂/ITO catalyst is indeed a valuable material for future applications in hydrazine fuel cells.
