Three‐Dimensional SnO₂ Nanowire Networks for Multifunctional Applications: From High‐Temperature Stretchable Ceramics to Ultraresponsive Sensors

Stretchable ceramic networks built from quasi-one-dimensional (Q1D) structures are important candidates for various applications of nanostructures in real-world technologies. A flame transport synthesis approach is developed that enables versatile synthesis of interconnected SnO2 nanowire networks. These SnO2 structures exhibit interesting defects that are very relevant for the oxide material-engineering community. Devices based on Q1D SnO2 structure networks show enormous potential for gas/UV sensing.
