CuO is a multifunctional metal oxide excellent for chemiresistive gas sensors. In this work, we report CuO-based NO2 sensors fabricated via chem. vapor deposition (CVD). CVD allows great control on composition, stoichiometry, impurity, roughness, and grain size of films. This endows sensors with high selectivity, responsivity, sensitivity, and repeatability, low hysteresis, and quick recovery. All these are achieved without the need of expensive and unscalable nanostructures, or heterojunctions, with a technol. mature CVD. Films deposited at very low temperatures (≤350°C) are sensitive but slow due to traps and small grains. Films deposited at high temperatures (≥550°C) are not hysteretic but suffer from low sensitivity and slow response due to lack of surface states. Films deposited at optimum temperatures (350-450°C) combine the best aspects of both regimes to yield NO2 sensors with a response of 300% at 5 ppm, sensitivity limit of 300 ppb, hysteresis of <20%, repeatable performance, and recovery time of ~1 min. The work demonstrates that CVD might be a more effective way to deposit oxide films for gas sensors. In the part of experimental materials, we found many familiar compounds, such as Bis(acetylacetone)copper(cas: 13395-16-9Application of 13395-16-9)
Bis(acetylacetone)copper(cas: 13395-16-9) catalyzes coupling and carbene transfer reactions. Metal acetylacetonates are used as catalysts for polymerization of olefins and transesterification. Application of 13395-16-9
