This Small Business Innovation Research (SBIR) Phase I project seeks to significantly advanceH2 gas sensing technologies by exploring a novel nanohybrid sensing platform of SnO2nanocrystals supported on carbon nanotubes (CNTs). The high demand of H2 as a clean energysource drives the fast growth of the H2 sensor market. Early detection of H2 is essential to thesafe handling of H2, and ultimately supports the market feasibility of a hydrogen economy.Currently, no single H2 sensor technology exists that can meet the leak detection and safetyfeatures required for the widespread use of H2. Miniaturized resistive sensors based on theproposed SnO2-CNT platform are promising for H2 detection with low cost, low energyconsumption, superior sensitivity at room temperature, and flexibility to realize selectivity.The broader/commercial impacts of this research are that miniaturized H2 sensors to bedeveloped will directly benefit society by enabling secure deployment of hydrogen fuel.Combining the unique properties of novel nanomaterials with rapid progress in microelectronicdevice fabrication promises low-cost, novel electronic device structures that can be readilyfabricated using existing microfabrication infrastructures. The major sensing materials used inthis platform, CNTs and SnO2, are affordable, particularly given the small amount of materialsneeded for each sensor. With a pre-fabricated sensor substrate, the sensor fabrication time is onthe order of minutes. The project will also train UWM graduate and undergraduate students inthe areas of nanomaterials, nanodevices, and green energy.
