Synthesis and study of sensor oxide nanofilms in a ZrO2-CeO2 system

Performance of a carbon monoxide sensor based on zirconia-doped ceria

“…Similarly, the fast response of ceria-based carbon monoxide sensors [12] can be improved by adding gold nanoparticles and/or clustering ceria nanoparticles [6]. However, there have been no reports of resistive-type carbon monoxide sensors using zirconia-doped ceria, just a single report [13] outlining the electrical conductivity of zirconia-doped ceria films in air and/or CO + CO 2 for the detection of oxygen levels. To address this shortcoming, resistive-type carbon monoxide sensors were fabricated using zirconia-doped ceria, the sensing properties of which are herein discussed through comparison with the performance of sensors based on non-doped ceria.…”

Review of the Synthesis, Characterization and Application of Zirconia Mixed Metal Oxide Nanoparticles

“…Different characterization techniques were used to analyze the formed nanomaterial and TEM was used in most of the literatures to determine the particle size. Although, Zirconia has been synthesized in combination with other metal oxides (25,(29)(30)41) for various applications there have been few reports on the antibacterial activity of zirconia mixed metal oxide nanoparticles therefore, more work needs to be done to investigate the combination of zirconia with other metal oxide to obtain improved antibacterial activity as zirconia nanoparticles has been reported to have some shortcoming (46) despite having antibacterial property.…”

“…Arsent'ev et al synthesize ZrO2-CeO2 nanoparticles using coprecipitation method (29) and Rossignol et al prepared ZrO2-CeO2 materials by using sol-gel and coprecipitation methods. It was reported that both the structure and the texture of the solids obtained depend on the synthetic route and the precursor used (23) .…”

“…Increasing temperature in hydrothermal process gave positive influence on the structural characteristics and will enhance the nucleation rate and linear growth rates of particle production (34) . Arsent'ev, et al, reported 10-12 nm size diameters for ZrO2-CeO2 synthesized by chemical precipitation with the phase depending on the percentage composition of each of the precursor present in the reaction (29) .…”

“…The application of ZrO2 mixed metal oxide nanoparticles was studied. ZrO2-CeO2 nanoparticles can be used as resistive sensors for the detection of the media with reduced pO2 as the composite has a response time and sensitivity due to the high diffusion coefficient on oxygen which is intrinsic for CeO2 based materials (29) . Other applications include as an antibacterial agent (25) , as a dielectric substance (26) , used in dental treatment (30) , fuel cell (31) and as electrochemical agent (41) .…”
