| Summary: | Developing a bio-sensor for rapid detection of biological hydrogen sulfide (bio-H2S) is of great significance to human health. Metal-oxide-semiconductor heterostructure based sensors have attracted extensive attention due to their large area, order structure, fast response, and high sensitivity. In this study, we prepared the Cu2O/NiO nanoarrays by the two-dimensional electrochemical in-situ assembly deposition method for bio-H2S detection. The sensors based on Cu2O/NiO nanoarrays were measured by a customized test system. The experimental results indicated that the sensor exhibited excellent sensitivity, low detection level and good
selectivity to bio-H2S in the range of 1 ∼ 200 µmol/L. Moreover, we proposed that the superior performance of the nanoarrays was mainly attributed to the synergistic effects of Cu2O/NiO heterostructure as well as vulcanization reaction of Cu2O. The results demonstrate that the Cu2O/NiO nanoarrays based sensor is a potential candidate for high performance bio-H2S sensor. |
