Enhanced Methane Sensing Properties of SnO₂ Nanoflowers With Ag Doping: A Combined Experimental and First-Principle Study

ppb-Level detection of isopropanol based on porous ZnSnO3/Ag through the synergistic effects of Ag and amorphous nanocube structures

“…This sensor outperformed the pure SnO 2 sensor in terms of long-term stability and selectivity. 29 The noticeable improvement in the gas sensing performance of oxide semiconductors can be attributed to the catalytic effect of precious metals. This occurs through two key mechanisms: electronic sensitization and chemical sensitization.…”
