Design optimization Co3O4 nanostructures hydrogen Project Details
| Abstract |
This research investigates the design and optimization of cobalt oxide (Co3O4) nanostructures, specifically thin films, for high-performance hydrogen sulfide (H2S) gas sensing applications. Metal oxide semiconductors, such as Co3O4, are recognized for their intrinsic chemical stability, tunable surface reactivity, and robustness, positioning them as pivotal materials in advanced gas detection. The study details the fabrication of Co3O4 thin films utilizing a scalable and cost-effective spray-coating process, aimed at evaluating their potential as active layers for H2S detection. Characterization of the resulting films revealed a well-defined porous morphology and strong optical absorption, features critical for enhancing surface-gas interactions and optimizing charge transport dynamics within the sensor. The optimized Co3O4 sensors demonstrated
an impressive and reproducible relative response of 17.59 towards H2S, alongside rapid response and recovery times of 20 seconds and 120 seconds, respectively. These performance metrics surpass those of many conventionally processed counterparts, thereby underscoring the efficacy of the spray-coating approach in precisely tailoring material microstructure and surface activity. The findings position spray-deposited Co3O4 thin films as promising candidates for developing next-generation, low-cost, and highly responsive H2S gas-sensing devices, applicable in critical areas such as industrial safety and environmental monitoring.
