Abstract
Pt particles with different nanosizes were loaded on reduced graphene oxides by a hydrothermal synthesis method.The morphology and composite of the products were examined by SEM and XPS.The hydrogen sensing properties of Pt-rGO based gas sensor were measured.The results indicate that the sample with smaller Pt particles has better hydrogen sensing property than that of the larger Pt particles sample in the operating temperature range of 50-150 ℃.The hydrogen sensing property of the Pt-doped reduced graphene oxides with smaller Pt particles (20-40 nm) gas sensor was also investigated at 80 ℃.The results demonstrate that the gas sensor exhibits excellent sensing performances and shows linear response to hydrogen in the range of 0.5％-2％ (volume fraction).All the response time is less than 180 s.The Pt-rGO based gas sensor also exhibits good reproducibility and high recovery ability,which has certain application prospects.关键词
