研究目的
To investigate the effect of the temperature and duration of heat treatment of a [Zn(H2O)(O2C5H7)2] solution in 1-butanol on the properties of ZnO nanoparticles and to test the obtained nanomaterials as a sensitive layer in detecting the most practically important gaseous analytes in air.
研究成果
The study demonstrated the high CO selectivity and sensitivity of ZnO coatings screen-printed using pastes based on nanopowders synthesized by heat treatment at 125°С for 2 and 4 h. The microstructure and particle size of ZnO were significantly influenced by the heat treatment conditions.
研究不足
The study is limited to the synthesis and characterization of ZnO nanoparticles under specific conditions and their application as gas sensors. The response time and sensitivity may vary with different synthesis conditions and gas concentrations.
1：Experimental Design and Method Selection:
The nanocrystalline zinc oxide was synthesized from zinc acetylacetonate hydrate [Zn(H2O)(O2C5H7)2] in 1-butanol under various temperatures (125–185°C) and durations (2, 4, and 6 h). The solid phase was separated by centrifugation, washed with ethanol, and dried.
2：Sample Selection and Data Sources:
The samples were characterized using X-ray powder diffraction, IR spectroscopy, thermal analysis, transmission electron microscopy, scanning electron microscopy, and atomic force microscopy.
3：List of Experimental Equipment and Materials:
Bruker D8 ADVANCE X-ray powder diffractometer, InfraLYuM FT-08 FTIR spectrometer, TA Instruments SDT Q600 simultaneous TGA/DSC analyzer, JEOL JEM-1001 transmission electron microscope, Carl Zeiss NVision 40 focused ion beam scanning electron microscope, Solver Pro-M scanning probe microscope.
4：Experimental Procedures and Operational Workflow:
The precursor solution was heat-treated under specified conditions, the solid phase was separated, washed, and dried. The obtained ZnO nanopowders were characterized and tested as gas sensors.
5：Data Analysis Methods:
The data were analyzed to determine the microstructure, particle size, and gas-sensing properties of the ZnO nanopowders.
