sonothermal , microwave and solution methods . However, evaporative/sputtering routes due to their high-energy preparation tend to yield p-type SnO thin films with uncontrolled n-SnO2 surface contaminations . Oxygen-poor environments such as carbothermal preparations or nitrogen-protected synthesis environments yield n-type SnO due to oxygen vacancies . In solution routes interesting and complex morphologies (frames, bowls, pompon, etc. ) of SnO, suitable for VOC detection, have been demonstrated in amine-based and long-chain organic solvents under solvothermal synthesis routes . If SnO is to be adopted as a MOX VOC sensor, its preparation will require controllability, scalability, and green synthesis chemistry. Simple and easily scaled reflux chemistry routes using green solvents to produce SnO particles suitable for VOC detection with reduced energy cost are available with reflux-solvent-controlled particle morphology . This work combines IPA reflux synthesis prepared p-type MOX SnO nanoflowers and additively manufactured conductive LIG to produce novel VOC sensors. This system requires only a low massloading of the SnO nanoflowers to achieve VOC sensitivity at room temperature. The resulting device requires fewer resources to produce and operate and is both sensitive and stable at ambient humidity and room temperature, all essential for application as resource-efficient VOC sensors for future applications, including worker safety.
