A highly sensitive oxygen sensor operating at room temperature based on platinum-doped In2O3 nanocrystals.

Abstract

Semiconducting In2O3 nanocrystals, synthesised via a nonaqueous sol-gel method and doped with 1 wt% of platinum, have shown to possess a unique high sensitivity to oxygen at room temperature (RT). Consequently, a Pt/In2O3-based oxygen sensor for room temperature operation has been developed showing higher performance compared to the state-of-the-art devices… (More)
