Background:

Microbial volatile organic compounds (MVOCs) pose health risks and serve as disease biomarkers.
Current detection methods for MVOCs are limited, necessitating advanced sensing technologies.
Semiconductor metal oxide (SMO) materials offer potential for sensitive gas detection.

To develop an efficient synthesis method for single-phase cubic ZnCo2O4 nanoparticles.

Main Methods:

Microwave-assisted solvothermal synthesis of ZnCo2O4 nanoparticles.
Calcination at 300 °C to achieve a single-phase cubic structure.
Characterization using X-ray Diffraction (XRD) and Fourier-Transform Infrared Spectroscopy (FTIR).
Gas sensing performance analysis for various volatile organic compounds (VOCs) at different temperatures.

Main Results:

Successfully synthesized pure, single-phase cubic ZnCo2O4 nanoparticles.
The ZnCo2O4 sensor exhibited high selectivity towards 1-pentanol.
Achieved a maximum sensor response of 83.6% to 100 ppm of 1-pentanol at 300 °C.

Conclusions:

An efficient method for producing single-phase cubic ZnCo2O4 nanoparticles was established.
ZnCo2O4 demonstrates enhanced gas-sensing properties for 1-pentanol detection.
This material holds promise for developing sensitive MVOC detection systems.
